Quick answer: The Islamic University of Technology (IUT) in Gazipur, Bangladesh, grades on a 4.00 scale. For undergraduate programmes, A+ (80% and above) is worth 4.00, A (75% to below 80%) is 3.75, A- (70% to below 75%) is 3.50, B+ (65% to below 70%) is 3.25, B (60% to below 65%) is 3.00, B- (55% to below 60%) is 2.75, C+ (50% to below 55%) is 2.50, C (45% to below 50%) is 2.25, D (40% to below 45%) is 2.00, and anything below 40% is F, worth 0.00. You pass a course at 40% aggregate marks, and you pass a semester only when you pass every course in it with a semester GPA of at least 2.00. Your GPA is your total grade points divided by your total credit hours taken. That one sentence is the whole system, and the rest of this guide is about the details that trip students up: the postgraduate table is slightly different, a referred examination is capped at a B grade, and a simple average of your semester GPAs is not your CGPA unless every semester carried the same number of credits.

IUT is not a standard Bangladeshi private university, and that matters for grading. It is a subsidiary organ of the Organisation of Islamic Cooperation (OIC), it sits at Board Bazar, Gazipur, about 30 km north of Dhaka, and its students come from OIC member states as well as Bangladesh. Its handbook is published department by department, and this guide is built from the university’s own August 2025 Electrical and Electronic Engineering (EEE) course structure and contents document, which reproduces the academic rules and regulations for both undergraduate and postgraduate programmes, together with the university’s July 2022 rules and regulations for postgraduate programmes. Where a rule could not be found in those official documents, this guide says so plainly instead of guessing. Always confirm a borderline case with your department or the Registrar, because your transcript, not this article, is the final record.

Check Your IUT GPA With the Calculator

Before you work through the formulas below, get a fast answer. Open the CGPAPro calculator on the homepage and enter each course with its credit hours and its letter grade. There is no separate IUT calculator page on this site, and you should not go looking for one under a guessed address. Use the homepage calculator and select the UGC Bangladesh grading scale. That choice is honest, not a workaround: for undergraduate courses, IUT’s published table matches the UGC Bangladesh table value for value, from A+ at 4.00 down to D at 2.00, so the grade points the calculator applies are exactly the grade points IUT applies. The one place you must be careful is the postgraduate table, where C is 2.00 rather than 2.25, as explained below. If you are a postgraduate student with a C grade, check that one course by hand.

To use the calculator well, enter sessional courses at their real credit values, not at 3.00 by habit. At IUT, a sessional subject taught for three periods a week carries 1.50 credit hours, and one taught for two periods a week carries 1.00 credit hour. Entering a 1.50-credit lab as a 3.00-credit course doubles its weight in your result and gives you a wrong GPA. Enter the credit hours from your course outline, enter the letter grade (not your raw percentage), and compare the calculator result with one hand calculation from the worked examples below. If the two disagree, the credit hours are almost always the cause.

What IUT Is, and Which IUT This Guide Is About

The name causes real confusion, so let us settle it first. This guide is about the Islamic University of Technology (IUT) at Board Bazar, Gazipur, Bangladesh, the OIC institution formerly known as the Islamic Institute of Technology and, before that, the Islamic Centre for Technical and Vocational Training and Research. It is not the Islamic University (IU) at Kushtia, Bangladesh, which is a separate public university with its own regulations. It is not the International Islamic University Chittagong (IIUC), and it is not any institution outside Bangladesh that happens to share the initials IUT. If your admission letter, student ID, or transcript says IUT, Gazipur, or iutoic-dhaka.edu, this is your guide. If it says Kushtia, you need a different guide.

IUT teaches in English, runs semesters of sixteen teaching weeks, and offers undergraduate programmes in engineering and technical education alongside postgraduate programmes in engineering, technical education, and business and technology management. The EEE department, whose handbook this guide draws on, is the university’s largest department, with an annual undergraduate intake of 180 students. The grading rules in section 2.7 of that handbook apply across departments, with one table for undergraduate programmes in engineering and all programmes of technical education, and a separate table for postgraduate programmes in engineering. That split is the single most important structural fact in this guide, because most second-hand summaries online collapse the two tables into one and quietly get the postgraduate C grade wrong. The same caution applies to other universities: the Khulna University grading guide, the Eastern University grading guide, the Green University grading guide, and the IIUC grading guide all use familiar 4.00 bands, but each university’s details differ, so always check the table for your own university.

The Official IUT Grading Table for Undergraduates

Here is the undergraduate table exactly as published in the August 2025 EEE handbook, approved by the 51st Academic Council. Marks are percentages of the total aggregate for the course, and the grade point is what enters your GPA calculation.

Marks obtained (percentage) Letter grade Grade point
80 and above A+ 4.00
75 to below 80 A 3.75
70 to below 75 A- 3.50
65 to below 70 B+ 3.25
60 to below 65 B 3.00
55 to below 60 B- 2.75
50 to below 55 C+ 2.50
45 to below 50 C 2.25
40 to below 45 D 2.00
Less than 40 F 0.00

Three things about this table deserve emphasis. First, the pass mark is 40% aggregate, not 40% in the final examination alone. Your attendance marks, quiz marks, mid-semester marks, and final examination marks are added together, and it is that total that decides your grade. A weak final can still pass if the rest of the semester was strong, and a strong final cannot rescue a semester in which you scored zero on missed quizzes and the mid-semester examination, because the handbook states plainly that a student missing any quiz, the mid-semester examination, or the semester final examination is considered to have got zero in that quiz or examination.

Second, there is no C- grade in the IUT undergraduate table. Some third-party tables floating around online insert a C- between C and D, or shift the C band. Do not use those tables. IUT’s undergraduate ladder goes C+ (2.50), C (2.25), D (2.00), F (0.00). If a calculator or a seniors’ spreadsheet shows you a C-, it is using somebody else’s scale.

Third, the bands are “to below” bands, so the boundary matters. A score of 79.9% is an A (3.75), not an A+, and a score of 74.9% is an A- (3.50), not an A. There is no rounding-up rule published in the handbook sections consulted for this guide, so do not assume that 79.5% becomes 80%. If your department rounds marks, that is a departmental practice you should confirm in writing, not an assumption to build a CGPA plan on.

How the Postgraduate Table Differs

The postgraduate table for engineering programmes looks almost identical to the undergraduate table, and that near-identity is exactly why it causes mistakes. Here it is, from the same handbook and from the July 2022 postgraduate rules:

Marks obtained (percentage) Letter grade Grade point
80 and above A+ 4.00
75 to below 80 A 3.75
70 to below 75 A- 3.50
65 to below 70 B+ 3.25
60 to below 65 B 3.00
55 to below 60 B- 2.75
50 to below 55 C+ 2.50
45 to below 50 C 2.00
Less than 45 F 0.00

The differences are two. There is no D grade at postgraduate level, so the pass floor rises from 40% to 45%: anything below 45% is an F. And a C is worth 2.00 at postgraduate level, not 2.25 as it is for undergraduates. A postgraduate student who copies the undergraduate table will overstate every C grade by 0.25 grade points, which is enough to move a borderline GPA across a threshold on paper while the transcript says something else.

The postgraduate pass standard is also higher in a second sense. The handbook states that the minimum average GPA for a pass at postgraduate level is 2.50, compared with the undergraduate semester-pass requirement of 2.00. And the postgraduate rules state that courses in which a student gets F are not counted towards credit hours earned or towards the GPA calculation, which is different from the undergraduate formula, where the GPA is total grade points divided by total credit hours taken. Postgraduate students should therefore not assume that an F drags their GPA in the same way an undergraduate F does; equally, an F still earns no credit, so it still delays completion. If you are a postgraduate student, confirm the current treatment of F grades with your department, because the interaction between the handbook statement and your semester grade sheet is exactly the kind of detail that is worth one email before you plan around it.

Postgraduate students also have a specific improvement route that undergraduates should not assume applies to them. Under the postgraduate rules, a student who obtains a C+ or C grade may be allowed to improve the grade of the course or courses by retaking the course or courses on payment of the course fee, and the retake is mentioned in the grade sheet. Note the wording: it is a permission (“may be allowed”), not an automatic right, and it is tied to C+ and C grades. Check the fee, the timing, and whether the improved grade fully replaces the old one before you register for a retake.

How Your Marks Become a Grade

For a theory course, or the theoretical part of a course, your aggregate is built from four parts: class attendance at 10% of total marks, class tests or quizzes at 15%, the mid-semester examination at 25%, and the semester-final examination at 50%. Four quizzes are held over the semester, and the best three count. The mid-semester examination covers the syllabus taught by then, and the final covers the entire syllabus. The tutorial part of a course is assessed continuously, and those marks are added to the corresponding theoretical or sessional course.

Attendance marks follow their own small table, and it is worth knowing because attendance is the easiest 10% you will ever earn or lose. Attendance of 95% and above earns the full 10 marks; 90% to below 95% earns 8; 85% to below 90% earns 6; 80% to below 85% earns 4; 75% to below 80% earns 2; and below 75% earns 0. The drop from 95% to 90% attendance costs you 2 marks out of 100, which is rarely the difference between grades on its own, but the drop below 75% costs you all 10 attendance marks, and that can easily be the difference between a C+ and a C, or between a D and an F. Sessional courses are assessed continuously, with a final examination sometimes also conducted.

Two non-grade marks also appear on IUT records and are worth knowing so they do not confuse your calculation. I (Incomplete) is given only when a student is unable to sit for the examination of a course at the end of the semester because of circumstances beyond his or her control. Under the postgraduate rules, the student must apply to the Head of Department through the advisor or supervisor within one week after the examination, and the I must be completed within the next two semesters if other rules permit, otherwise it becomes an F. W (Withdrawn) is given to a student who withdraws in writing from a course four weeks before the completion of the semester, under the postgraduate rules. S (Satisfactory) and U (Unsatisfactory) grades are given for thesis work only. None of I, W, S, or U carries a grade point, so none of them should be entered into a GPA calculator as a number.

Step by Step: How to Calculate Your GPA

The method is the same for every semester, and it is worth doing once by hand even if you normally use a calculator, because doing it once teaches you where the weight really sits.

  1. List every course you took in the semester, with its credit hours and its final letter grade. Leave out audit courses and any course graded S, U, I, or W, because those carry no grade point.
  2. Convert each letter grade to its grade point using the correct table: undergraduate or postgraduate. This is the step where most errors happen, usually by using the wrong table for a C grade or by inventing a C- grade.
  3. Multiply each course’s credit hours by its grade point. That product is the course’s grade points earned.
  4. Add up all the grade points earned. Add up all the credit hours.
  5. Divide total grade points earned by total credit hours. That is your semester GPA.

For your CGPA, do not average your semester GPAs. Instead, add up the grade points earned across all semesters you have completed, add up the credit hours across all those semesters, and divide the first total by the second. Equivalently, multiply each semester GPA by that semester’s credit hours, add those products, and divide by total credit hours. The worked examples below show both the right way and the tempting wrong way, with real numbers, so you can see how large the gap can be.

The Formula

Semester GPA = (sum of credit hours x grade point for each course) / (total credit hours taken in the semester).

CGPA = (sum of grade points earned across all completed semesters) / (total credit hours across all completed semesters).

That is all there is to it. There is no separate weighting for theory versus sessional courses beyond their credit hours, and no bonus for a difficult course. A 3.00-credit theory course at B (3.00) contributes exactly as much as a 3.00-credit course at B in any other subject, and a 1.50-credit sessional course contributes exactly half as much as a 3.00-credit course at the same grade. Credit hours are the only weights.

Worked Example 1: One Semester, Five Courses

Imagine a first-semester undergraduate student with this result:

Course Credit hours Grade Grade point Grade points earned
Mathematics 3.00 A 3.75 3.00 x 3.75 = 11.25
Physics (theory) 3.00 A- 3.50 3.00 x 3.50 = 10.50
Physics (sessional) 1.50 B+ 3.25 1.50 x 3.25 = 4.875
English 3.00 B 3.00 3.00 x 3.00 = 9.00
Workshop practice 1.50 A+ 4.00 1.50 x 4.00 = 6.00

Total credit hours = 3.00 + 3.00 + 1.50 + 3.00 + 1.50 = 12.00. Total grade points earned = 11.25 + 10.50 + 4.875 + 9.00 + 6.00 = 41.625. Semester GPA = 41.625 / 12.00 = 3.46875, which is reported as 3.47. This student has passed every course and is comfortably above the 2.00 semester-pass floor, so the semester is passed. Notice how the two sessional courses together contribute 10.875 of the 41.625 points: small courses matter, but only in proportion to their credits. If this student had entered both sessional courses as 3.00 credits by mistake, the calculator would have returned a different GPA and the student would have planned the next semester around a fiction.

Worked Example 2: Two Semesters Combined Into a CGPA

Now extend the story. In the first semester, the student completes 15 credit hours with total grade points of 52.50. First-semester GPA = 52.50 / 15 = 3.50. In the second semester, the student completes 15 credit hours with total grade points of 48.00. Second-semester GPA = 48.00 / 15 = 3.20. The CGPA after two semesters is not a guess and not a feeling; it is (52.50 + 48.00) / (15 + 15) = 100.50 / 30 = 3.35.

Because both semesters carried the same number of credits here, the simple average of the two GPAs happens to give the same answer: (3.50 + 3.20) / 2 = 3.35. That coincidence is dangerous, because it teaches students a shortcut that fails the moment credit loads differ, which they almost always do. The next example shows the failure.

Worked Example 3: The Plain-Average Trap

Consider a student whose first semester is heavy and strong, and whose second semester is light and weak. First semester: 18 credit hours, GPA 3.80, so grade points earned = 18 x 3.80 = 68.40. Second semester: 12 credit hours, GPA 2.50, so grade points earned = 12 x 2.50 = 30.00. The tempting calculation is the plain average: (3.80 + 2.50) / 2 = 3.15. The correct calculation is the credit-weighted one: (68.40 + 30.00) / (18 + 12) = 98.40 / 30 = 3.28.

The gap is 0.13, which is large enough to matter. The plain average understates this student, because it gives the weak 12-credit semester the same weight as the strong 18-credit semester, when in reality the strong semester represents more work. The error runs the other way for a student whose weak semester was the heavy one: the plain average would flatter them. Either way, the transcript does not use a plain average, so your planning should not either. If you ever catch yourself adding semester GPAs and dividing by the number of semesters, stop and multiply by credits first.

The same trap appears in a smaller form inside a single semester. Averaging letter grades, or averaging grade points without weighting by credits, gives the same kind of error. A 1.50-credit sessional A+ does not cancel a 3.00-credit theory C in a plain average of grade points, because the theory course carries twice the weight. Always multiply by credits before you add.

Worked Example 4: A Referred Examination, Capped at B

This is the example that most IUT students actually need, and it is the one most online summaries get wrong by omitting the cap. Suppose an undergraduate student finishes a 15-credit semester with these grades: a 3.00-credit course at A (3.75) gives 11.25 points; a 3.00-credit course at B+ (3.25) gives 9.75 points; a 3.00-credit course at B (3.00) gives 9.00 points; a 3.00-credit course at C+ (2.50) gives 7.50 points; and a 3.00-credit theory course failed with F (0.00) gives 0.00 points. Total grade points = 11.25 + 9.75 + 9.00 + 7.50 + 0.00 = 37.50. Semester GPA before any referred examination = 37.50 / 15 = 2.50. The student has not passed the semester, because passing requires passing every course, even though the GPA is above 2.00.

The student has failed only one theory course, which is within the handbook’s limit: a student failing in not more than two theoretical courses may sit for a referred examination, normally held within two weeks of the commencement of the next semester, covering the entire syllabus. Suppose the student passes the referred examination. The grading for a subject passed this way is capped at a maximum of B grade, whatever marks the student actually scores in the referred examination. So the failed course now counts as B (3.00), giving 3.00 x 3.00 = 9.00 points instead of 0.00. The new total is 37.50 + 9.00 = 46.50, and the revised semester GPA = 46.50 / 15 = 3.10.

Two lessons follow. First, the referred examination is genuinely valuable: it lifts this student from an unpassed semester at 2.50 to a passed semester at 3.10. Second, the cap is real money left on the table by design: even a brilliant referred performance cannot earn an A or A+ for that course. If you are deciding how much revision time to give a referred course versus your new semester’s courses, that cap should shape the decision. The referred examination gets you to a B and to a passed semester; the new semester’s courses are where A grades are still available. If the student fails the referred examination, the handbook says he or she may sit for a backlog examination as per the rules, and the details of that backlog route are one of the items marked UNVERIFIED below, because the handbook sections consulted do not spell out its full procedure.

GPA Versus CGPA, in Plain Language

Your semester GPA describes one semester. Your CGPA describes everything completed so far, weighted by credits. A single bad semester lowers your CGPA but does not define it, because every completed course stays in the credit-weighted total, which is why early semesters matter more than students expect.

It also explains why “I need a 3.75” is an incomplete plan. A target CGPA only becomes a plan when you combine it with your completed credits, your completed grade points, and your remaining credits. The arithmetic is: required average in remaining courses = (target CGPA x total credits at graduation – grade points already earned) / remaining credits. If that required average comes out above 4.00, the target is mathematically impossible on the remaining courses, and it is better to learn that now than in your final semester. If it comes out at, say, 3.60, you know exactly what standard your remaining courses must meet. Work it out on paper once, then use the calculator to test different grade combinations for the coming semester.

One more distinction matters at IUT specifically. The handbook uses “GPA” for the semester figure (total grade points divided by total credit hours taken) and “CGPA” for the cumulative figure, and it uses CGPA, not a separate honours calculation, for class and medal decisions. Your class at graduation is decided by your final CGPA, as set out below, not by your best semester or your final-year average.

Referred, Backlog, and Retake Rules

Pulling the rules together in one place, because they are scattered across the handbook: an undergraduate student who fails in not more than two theoretical courses may sit for referred examinations, normally within two weeks of the commencement of the next semester, covering the entire syllabus of each course. A pass in a referred examination is graded under the normal grading system but capped at a maximum of B. A failure in the referred examination leads to a backlog examination as per the rules. A student is declared to have passed a semester examination when he or she passes all courses of the semester with a minimum GPA of 2.00 for undergraduate programmes.

For postgraduate students, the corresponding rules are: the minimum average GPA for a pass is 2.50; F courses earn no credit and are excluded from the GPA calculation under the postgraduate rules; a C+ or C grade may be improved by retaking the course on payment of the course fee, with the retake mentioned in the grade sheet; and an I grade must be completed within the next two semesters or it becomes an F. Withdrawal in writing four weeks before the completion of the semester earns a W grade at postgraduate level.

What the handbook sections consulted do not clearly settle for undergraduates is a general improvement retake for a low passing grade (as opposed to the referred route for failed courses, and as opposed to the postgraduate C+/C improvement rule). Many students assume they can retake any C or D to raise their CGPA. That assumption is UNVERIFIED for IUT undergraduates from the sources used here. Before you pay a fee or plan a semester around an undergraduate improvement retake, confirm with your department whether it exists, what the fee is, whether the new grade replaces the old one, and whether any cap applies, as it does for referred examinations. The same caution applies to backlog examination procedure, which the handbook mentions but does not fully detail in the sections consulted.

Class, Honours, and Gold Medals

IUT classifies its awards as First Class with Honours, First Class, and Second Class, except that no class is awarded in the case of the Master of Technical Education. The thresholds, from the handbook, are: a student securing a CGPA of 3.75 and above is placed in First Class with Honours; a student securing a CGPA of 3.00 and above is placed in First Class; and other successful candidates are placed in Second Class. Note the consequence: a graduating CGPA of 3.74 is First Class, not First Class with Honours, however close it feels. The 3.75 line is a cliff, not a slope, and students sitting just below it in their final year should know exactly how many grade points stand between them and the line, using the target calculation in the GPA-versus-CGPA section above.

Two medals sit above the class system. The IUT Gold Medal is awarded department-wise to the student who gets the highest CGPA at the end of the programme, provided that CGPA is not less than 3.80 out of 4.00, among programmes of each department having a duration of two years or more. The OIC Gold Medal is awarded to a student who secures at least a CGPA of 3.90 out of 4.00 at the end of the programme and tops the list of all successful students of all programmes of all departments. A student who becomes eligible for both medals receives only the OIC Gold Medal. These are programme-end awards based on final CGPA and ranking, not semester prizes, so a single strong semester does not earn them and a single weak early semester does not necessarily rule them out.

Students often ask about a Dean’s List at IUT. No Dean’s List rule or threshold was found in the handbook sections consulted, so this guide does not claim one exists; if your department publishes one, follow its notice. The same applies to undergraduate probation: the sections read state the semester-pass standard (pass all courses, GPA at least 2.00) but no general probation ladder. Do not import another university’s probation rule and act on it.

Common Mistakes IUT Students Make

  • Using the postgraduate C value (2.00) for an undergraduate course, or the undergraduate C value (2.25) for a postgraduate course. Check which table you are in before you calculate.
  • Inventing a C- grade. IUT’s undergraduate table has no C-. If a spreadsheet shows one, the spreadsheet is wrong for IUT.
  • Averaging semester GPAs instead of weighting by credits. The plain-average trap in Worked Example 3 costs up to 0.13 in a realistic case, and more when credit loads differ further.
  • Entering sessional courses at 3.00 credits. A three-period sessional course is 1.50 credits, and a two-period one is 1.00 credit. Wrong credits give a wrong GPA even when every grade is right.
  • Assuming a referred examination can earn an A+. It cannot: the grade is capped at B, however well you perform.
  • Treating 40% as a final-examination pass mark. It is a 40% aggregate pass mark for undergraduates (45% at postgraduate level). Missed quizzes and mid-semester examinations count as zero and drag the aggregate down before the final is even sat.
  • Assuming attendance marks do not matter. Below 75% attendance, the attendance component is zero out of 10, which can be the whole gap between a pass and a fail.
  • Confusing IUT Gazipur with Islamic University, Kushtia, or IIUC, and applying the wrong university’s table, retake rule, or calculator to an IUT transcript.
  • Converting a 5.00-scale school GPA into a 4.00-scale university CGPA by simple multiplication. The two scales measure different stages of education and are not convertible that way; scholarship and credential evaluators look at the underlying marks and grades, not at a multiplied number.
  • Planning around an unverified improvement retake for an undergraduate passing grade. Confirm the rule exists for your programme before you count on it.

Tips to Protect and Raise Your CGPA

First, protect the cheap marks. Attendance at 95% or above is 10 marks for showing up and paying attention, and the best-three-of-four quiz rule means one bad quiz day does not have to hurt you, provided you do not miss quizzes altogether. A missed quiz is a zero that the best-three rule cannot remove if you have already used your discard, and a missed mid-semester examination is a quarter of the course gone.

Second, weight your revision by credits, not by worry. An hour spent on a 3.00-credit theory course moves your GPA twice as much as an hour spent on a 1.50-credit sessional course at the same grade improvement, and an hour spent lifting a course across a grade boundary (say, from 74% to 75%, A- to A) is worth 0.25 grade points times the course’s credits, while an hour spent lifting a course from the middle of one band to the top of the same band is worth nothing in GPA terms. Aim revision at boundaries first.

Third, know your number before each semester starts. Write down your completed credits, your completed grade points, and your current CGPA. Then, before registration, work out what average you need in the coming semester to hold your CGPA, to reach 3.00, or to reach 3.75. That one calculation turns vague pressure (“I must do well”) into a concrete standard (“I need an average of 3.60 across 15 credits, which means mostly A- and above”). It also tells you early when a target is out of reach, so you can reset the target instead of discovering the fact in your final semester.

Fourth, treat the referred examination as a safety net with a ceiling, not as a second full attempt. If you are at risk in more than two theory courses, the referred route does not cover you at all, because it is limited to not more than two failed theory courses. That is the point at which talking to your advisor early, rather than after results, matters most. And if you do sit a referred examination, remember the B cap when you divide revision time between the referred course and the new semester.

Frequently Asked Questions

Is IUT’s grading system the same as the UGC Bangladesh grading system?

For undergraduates, the bands and grade points match the UGC Bangladesh table exactly, from A+ at 4.00 down to D at 2.00, with F below 40%. That is why the homepage calculator’s UGC Bangladesh scale gives correct undergraduate grade points. The match is not total, though: IUT’s postgraduate table differs at C (2.00, not 2.25) and at the pass floor (45%, not 40%), and IUT’s referred-examination cap and class thresholds are IUT’s own rules, not UGC rules. Use the UGC scale for undergraduate arithmetic, and IUT’s own rules for everything else.

What is the pass mark at IUT?

For an undergraduate course, 40% of the total aggregate marks. For a postgraduate course, 45%. Passing a course is not the same as passing a semester: an undergraduate passes a semester only by passing every course in it with a semester GPA of at least 2.00, and a postgraduate needs a minimum average GPA of 2.50.

What CGPA do I need for First Class with Honours at IUT?

A final CGPA of 3.75 or above. A CGPA of 3.00 or above gives First Class, and other successful candidates are placed in Second Class. No class is awarded for the Master of Technical Education.

Does an F grade count in my GPA?

At undergraduate level, the published formula divides total grade points by total credit hours taken, and an F contributes 0.00 grade points for its credits, so it drags the GPA down until the course is passed through the referred or backlog route. At postgraduate level, the postgraduate rules state that F courses are not counted towards credit hours earned or towards the GPA calculation. The two levels differ, so do not apply one level’s rule to the other, and confirm the treatment on your own grade sheet if anything looks inconsistent.

Can I improve a low grade by retaking the course?

It depends on your level and on the grade. A failed theory course (up to two of them) can be addressed through a referred examination, capped at B. At postgraduate level, a C+ or C grade may be improved by retaking the course on payment of the course fee, subject to permission, with the retake noted on the grade sheet. A general undergraduate improvement retake for a passing grade is UNVERIFIED from the handbook sections consulted: confirm with your department before you plan around it.

What happens if I fail the referred examination?

The handbook states that a student who fails the referred examinations may sit for a backlog examination as per the rules. The full backlog procedure (timing, fee, grade cap, and how many attempts are allowed) is UNVERIFIED from the sections consulted for this guide, so ask your department for the current backlog notice rather than assuming the referred rules carry over unchanged.

Is IUT the same as Islamic University (IU), Kushtia?

No. IUT is the OIC institution at Board Bazar, Gazipur. Islamic University, Kushtia, is a separate Bangladeshi public university, and IIUC (International Islamic University Chittagong) is a third, separate institution. They have different regulations, different handbooks, and different administrative offices. Make sure any table, calculator setting, or seniors’ advice you use is for IUT Gazipur specifically.

Can I convert my IUT CGPA to a percentage?

There is no official IUT percentage-conversion formula published in the handbook sections consulted, so this guide does not offer one. The common shortcut of multiplying CGPA by 25 (so that 4.00 becomes 100%) is not an IUT rule and should not be written on an application as if it were. If a scholarship, employer, or credential evaluator asks for a percentage, give them your actual marks and grades and let their own conversion apply, or ask the Registrar for an official conversion or transcript note.

Conclusion

IUT’s grading system rewards students who understand two things: the table, and the weight. The table is a familiar 4.00 ladder with two traps in it, the postgraduate C value and the missing C- grade. The weight is credit hours, and every CGPA mistake in this guide comes from forgetting that weight. Add the referred-examination cap at B, the 40% undergraduate and 45% postgraduate pass floors, the 2.00 undergraduate semester-pass standard and the 2.50 postgraduate average, and the class thresholds at 3.00 and 3.75, and you have the complete working picture. Check your numbers with the homepage calculator, verify them once by hand, and when a rule is marked UNVERIFIED here, confirm it with your department before you act on it.
