Quick answer: BAIUST grades on the UGC uniform 4.00 scale: 80% and above is an A+ worth 4.00, 75% is an A worth 3.75, and the scale runs down to D at 2.00 for 40-44%, with anything below 40% an F worth 0.00. Your semester GPA is the credit-weighted average of your grade points, and your CGPA is the credit-weighted average of your semester GPAs. What makes BAIUST different from most private universities is not the scale. It is what happens when you fail: a three-stage ladder of referred exams, backlog exams and term repeats, with its own rules for improvement, withdrawal and honours. This guide covers the full table, the formulas with worked examples, and every one of those rules, taken from BAIUST’s own published policy.
What BAIUST Is
The Bangladesh Army International University of Science and Technology, usually shortened to BAIUST, is an army-run private university in Cumilla. Its permanent campus sits at Syedpur in Adarsha Sadar, Cumilla, and the university celebrated its 11th founding anniversary in 2026, which puts its founding in 2015. The Vice-Chancellor is Brigadier General Md Kamal Uddin Komol, and the campus runs on a disciplined, army-administered model that students notice from their first week: structured routines, close mentoring and a strong emphasis on attendance and conduct.
BAIUST teaches Outcome-Based Education, usually called OBE. In practice that means every course states what a student should be able to do by the end of it, and the assessment is built around those outcomes rather than around memorised notes. The CSE department, for example, designed its courses for accreditation from the Board of Accreditation for Engineering and Technical Education (BAETE), and its OBE-based curriculum has applied to all students admitted from Spring 2022 onwards.
The undergraduate programmes and their approved seats are:
- BSc in Computer Science and Engineering (CSE) – 100 seats, 4 years, 154 credit hours
- BSc in Electrical and Electronic Engineering (EEE) – 100 seats, 4 years
- BSc in Civil Engineering (CE) – 50 seats, 4 years
- Bachelor of Business Administration (BBA) – 100 seats, 4 years
- BA (Hons) in English – 50 seats, 4 years
- LLB (Hons) – 50 seats, 4 years
Admission is through BAIUST’s own admission test and viva, run from admission.baiust.ac.bd. The grading rules in this guide apply across all of these programmes, because BAIUST publishes one general academic policy for the whole university rather than a separate rulebook per department.
Check Your BAIUST GPA With the Calculator
BAIUST does not publish its own official CGPA calculator, and our site does not yet have a dedicated BAIUST calculator page either. The honest workaround is the homepage calculator on cgpacalculatorpro.com, which runs on the exact same UGC 4.00 scale BAIUST uses, so the number it gives you is the number BAIUST’s own table gives.
To use it, add one row per course, pick the letter grade from the dropdown, type the credit hours for that course, and read your semester GPA from the result. Add a second semester the same way and it gives you the cumulative figure too. Two things to get right: enter the credits exactly as they appear on your course outline, because a 3-credit course counts three times as much as a 1-credit lab, and use the letter grade from your result sheet, not the percentage, because the grade point comes from the letter.
The worked examples later in this guide use the same numbers the calculator produces, so you can check your own calculation against them line by line.
The BAIUST Grading Table
BAIUST follows the UGC uniform 4.00 grading scale used across Bangladesh. One point needs stating plainly: BAIUST’s website publishes its examination, retake and withdrawal rules in detail, but it does not publish a standalone grade table of its own. The table below is the UGC scale as listed for BAIUST by the BAIUST-specific CGPA calculator at Smart Study Box, and it matches the UGC scale published by BAUET and every other university in this cluster. If your department handbook ever shows a different band, the handbook wins. Check it before you dispute a grade.
| Marks (%) | Letter Grade | Grade Point | What it means |
|---|---|---|---|
| 80 and above | A+ | 4.00 | Outstanding |
| 75 to 79 | A | 3.75 | Excellent |
| 70 to 74 | A- | 3.50 | Very good |
| 65 to 69 | B+ | 3.25 | Good |
| 60 to 64 | B | 3.00 | Satisfactory |
| 55 to 59 | B- | 2.75 | Above average |
| 50 to 54 | C+ | 2.50 | Average |
| 45 to 49 | C | 2.25 | Below average |
| 40 to 44 | D | 2.00 | Pass |
| Below 40 | F | 0.00 | Fail |
Three things about this table decide most students’ results. First, D is the minimum passing grade: 40% earns you the credit, 39% earns you nothing. Second, the bands are five marks wide, which means a single mark can move you a full grade. A 74% is an A- at 3.50; a 75% is an A at 3.75. That one mark is worth 0.25 grade points on that course. Third, the F is worth 0.00, but an F does not simply sit in your average the way a low grade does. An F has to be cleared through the referred, backlog or retake route explained below, and until it is cleared, the course contributes no earned credit.
BAIUST also uses three non-numerical grades that never carry grade points. W means Withdrawn, given when a student withdraws from a term on approved medical grounds after missing more than 40% of classes. I means Incomplete, given when a term registration is cancelled after more than 40% absence without notification and prior approval. And an F is given to a student who attended more than 60% of classes but did not sit the examination after collecting the admit card. None of these three enters the GPA calculation as a number, but all three affect whether you are allowed to continue, which is covered in the withdrawal section.
How to Calculate Your Semester GPA
Semester GPA is the credit-weighted average of the grade points you earned in that term. The formula is:
GPA = total of (grade point x credit hours) for every course, divided by total credit hours
Here is a full worked example, using a realistic first-term CSE load of five courses and 14 credits. Every number below follows the table above.
| Course | Marks | Grade | Grade Point | Credits | Points |
|---|---|---|---|---|---|
| CSE 101 | 82% | A+ | 4.00 | 3 | 12.00 |
| EEE 102 | 76% | A | 3.75 | 3 | 11.25 |
| MATH 103 | 71% | A- | 3.50 | 3 | 10.50 |
| PHY 104 | 66% | B+ | 3.25 | 3 | 9.75 |
| HUM 105 | 58% | B- | 2.75 | 2 | 5.50 |
| Total | 14 | 49.00 |
GPA = 49.00 / 14 = 3.50.
Notice what the weighting does. The B- in HUM 105 looks like the weak result, but it is only a 2-credit course, so it costs 5.50 points out of 49.00. If that same B- had been in a 3-credit course, it would have cost 8.25 points and the GPA would have dropped to 3.42. This is why students who protect their heavy courses first, and treat a 1-credit lab as a free grade, usually end up with the higher GPA. It is also why you should never average your grade points without the credits. A plain average of 4.00, 3.75, 3.50, 3.25 and 2.75 is 3.45, which is wrong. The correct, credit-weighted answer is 3.50.
How to Calculate Your CGPA
CGPA is the credit-weighted average of your semester GPAs across every term you have completed. The formula is:
CGPA = total of (semester GPA x semester credits) for every term, divided by total credits earned
Continuing the same student: Term 1 ended at GPA 3.50 over 14 credits, which is 49.00 grade points. Suppose Term 2 ends at GPA 3.25 over 15 credits, which is 48.75 grade points. Then:
CGPA = (49.00 + 48.75) / (14 + 15) = 97.75 / 29 = 3.37.
That 3.37 is the number that appears on the transcript, decides scholarship eligibility and is the first thing an employer or a foreign university reads. A single good term cannot rescue a weak start quickly, because the CGPA is dragged by every credit you have ever taken. That is also the reason the improvement rules in this guide matter so much: they are the only way to change a grade that is already pulling your CGPA down.
One calculation students ask about constantly is target-setting: what GPA do I need next term to reach a CGPA I want? Take the same student, sitting at 97.75 points over 29 credits (CGPA 3.37), who wants a 3.50 after Term 3. Term 3 carries 15 credits, so the total will be 44 credits. A 3.50 CGPA over 44 credits needs 154.00 points in total. The student already has 97.75, so Term 3 must produce 56.25 points. 56.25 / 15 = 3.75. The answer is a 3.75 GPA next term: every course at A or better, on average. Run the same calculation with your own numbers before a term starts, and you will know exactly what you are aiming at instead of guessing.
GPA vs CGPA: The Difference That Matters
| GPA | CGPA | |
|---|---|---|
| Covers | One term only | Every term completed so far |
| Changes | Fresh every term | Moves slowly, term by term |
| Decides | Promotion to the next term, referred-exam eligibility | Graduation, honours, gold medal, Dean’s and VC’s Lists |
| Can you fix it? | Only by doing better next term | By improving old grades and earning strong new ones |
At BAIUST the distinction has a practical edge. Promotion and the referred-exam route run off the term result, while the serious consequences, withdrawal from the programme and the honours lists, run off the CGPA. A student can have a bad term and still be safe overall, or a decent term and still be in trouble overall. Always check both numbers after every result.
What Happens If You Fail: BAIUST’s Three-Stage Ladder
This is the section no other guide covers, because it comes from BAIUST’s own published general policy. BAIUST does not treat all failures the same way. It runs a ladder, and which rung you are on decides what you are allowed to do next.
Stage 1: The Referred Examination
If you fail a maximum of two theoretical courses in the final examination of a term, you are promoted to the next term, and you are allowed to sit a referred examination, also called a re-examination, on the failed course or courses at the end of that term, as per the academic schedule. The re-examination is normally conducted from the third week of the following semester.
Three details make this stage generous. First, when you sit the re-examination for a course you previously failed, you are eligible to get the grade as earned. There is no cap. If you earn an A in the re-examination, you get an A. That is a real difference from some other army universities, where a re-examination grade is capped at B or B+. Second, you must apply to appear, pay the prescribed fee, and take the recommendation of your mentor or student advisor before you sit. Third, if you fail a sessional course, the rule is different: you must attend the sessional classes and examinations again to clear it in one of the next consecutive terms, and your performance is evaluated under the sessional marks distribution policy. A sessional failure cannot be cleared by a written re-examination alone.
Stage 2: Backlog
If you fail, or are absent again, in the referred examination of a failed course in the immediate semester, that course is termed a backlog course. A backlog student is allowed to appear at the re-examination of the backlog course in the following term only, and must clear it in that backlog examination. If the course is not cleared then, the student has to retake the course in one of the subsequent semesters.
Two limits apply at this stage. A student is allowed to appear at the re-examination of a maximum of four theoretical courses, or 12 credits, in a single-term re-examination programme. And registration for a retake course is done through IUMSS at the beginning of each term or semester, just like any other new course, with a scheduled fee and the mentor’s recommendation.
Stage 3: Term Repeat
If you fail three or more theoretical courses in the term final examination, you repeat the same term, with registration. This is the hard rung of the ladder, and it is where BAIUST’s system differs most from a simple repeat-a-course model.
Students repeating a term may seek exemption for the course or courses they passed in the previous term. If the exemption is granted, the previous grade of that course is carried forward for the onward GPA and CGPA calculation, which means the student does not attend classes or appear at class tests or examinations for the exempted course in the repeat term. If a student repeats a term, for example Level 1 Term 1, and fails again in three or more theoretical courses in that term, the case requires approval from the Academic Council for further consideration.
| Failed theory courses in the term final | What happens |
|---|---|
| 1 to 2 | Promoted; referred examination at the end of the term, grade as earned |
| Failed the referred exam too | Course becomes backlog; one re-examination chance next term, then retake |
| 3 or more | Repeat the whole term; passed courses can be exempted with grades carried forward |
| 3 or more again in the repeated term | Academic Council approval required to continue |
Grade Improvement: How to Raise an Old Grade
BAIUST allows improvement, and the rule is more generous than most students expect. If you obtain a grade of B or below B in a course, you are allowed to appear for the re-examination only once for that course for the purpose of grade improvement, and you are eligible to get the grade as earned. A student can appear in the improvement examination for a particular subject within the next three consecutive semesters, and can appear for a maximum of six courses in a four-year graduation programme. The improved grade is shown in the transcript, and the better grade, the higher grade, is considered as the final grade for the GPA calculation of that term. As with every other re-examination, the student must take the recommendation of the mentor or student advisor.
Worked example: a student finishes a 15-credit term at GPA 3.20, which is 48.00 points. One 3-credit course sits at B, worth 9.00 points. The student improves it to A-, worth 10.50 points. The term total becomes 49.50 points, and the term GPA becomes 49.50 / 15 = 3.30. One improvement, properly used, lifted the whole term by 0.10.
Because the allowance is only six courses across the whole degree, spend it where it pays. Improving a 3-credit B to an A- gains 0.75 points per course; improving a 1-credit course gains almost nothing. And because the window is the next three consecutive semesters, do not let an improvable grade drift past its deadline. A B that could have become an A- in your second year is gone by your fourth.
Term Withdrawal and Programme Withdrawal
BAIUST’s withdrawal rules are strict, and they are the part of the policy students most often discover too late.
Term withdrawal. In the case of severe sickness that leads to missing more than 40% of classes, supported by the requisite medical documents, a student may be allowed to withdraw the term and repeat the whole term with re-registration in the regular term of the next academic session, subject to approval of the Academic Council. The student gets a W grade in that case. If a student does not attend more than 40% of classes without notification and prior approval, the term registration is cancelled and the courses are treated as Incomplete. The student must repeat the term with re-registration in the next academic session, subject to Academic Council approval, and gets an I grade. If a student attends more than 60% of classes but does not appear in the examination after collecting the admit card, the student gets an F grade. If a student does not attend classes for two consecutive terms without prior approval and wishes to continue from the next academic session, the student is penalised for each term and may be allowed to repeat the term with re-registration, subject to Academic Council approval, and gets an F grade in that case.
Programme withdrawal. Failure to secure a minimum CGPA of 2.25 in two consecutive levels also leads to withdrawal from the programme. If a student does not attend classes for two consecutive terms without notification and prior approval, the student is permanently withdrawn from the programme. And every student must complete the whole undergraduate programme within seven academic years from the date of registration, or be withdrawn. The mentor or student advisor must recommend any such withdrawal.
The 2.25 rule deserves attention. The commonly quoted graduation minimum for BAIUST is a CGPA of 2.00, but 2.25 is the line that actually ends a degree: two consecutive levels below 2.25 and the programme withdraws you. Treat 2.25, not 2.00, as the real floor, and treat the seven-year limit as a hard deadline. A student who repeats terms and accumulates backlogs can run out of years faster than expected.
Honours, Gold Medal, and the VC’s and Dean’s Lists
BAIUST recognises strong performance in three ways, all of them based on the final CGPA.
- Degree with Honours: a candidate for a bachelor’s degree is awarded the degree with honours if the overall CGPA is 3.75 or better.
- Gold Medal: awarded to all students earning a CGPA of 4.00 at the end of the entire programme, and to the first position holder in each department earning a minimum CGPA of 3.80.
- VC’s List and Dean’s List: certificates awarded to graduating students based on their earned CGPA, considering the results of the entire programme from Level 1 to Level 4.
One honest gap: the exact CGPA thresholds for the VC’s List and the Dean’s List are not published in readable form. BAIUST’s policy page states that the lists exist and that they are based on the whole-programme CGPA, but the threshold table on that page is an image file that is currently offline, so the numbers cannot be verified. Ask the Controller of Examinations for the current thresholds before you plan around them. The honours and gold medal figures above, by contrast, are stated in the policy text itself and are verified.
BAIUST vs BAUET vs BAUST: Do Not Mix Them Up
The three army universities are the single biggest source of confusion in search results, and even the BAUST guide on this site has to disambiguate them. All three are army-run, all three use the UGC 4.00 scale, and all three have similar names. They are different universities in different cities with different rules.
| BAIUST | BAUET | BAUST | |
|---|---|---|---|
| Full name | Bangladesh Army International University of Science and Technology | Bangladesh Army University of Engineering and Technology | Bangladesh Army University of Science and Technology |
| Location | Cumilla (Syedpur) | Qadirabad, Natore | Saidpur, Nilphamari |
| Focus | Science, technology, business, law | Engineering and technology | Science and technology |
| Re-exam grade | As earned, no cap | Check the BAUET guide | Capped at B, B+ or B depending on exam type |
| Improvement | B or below, once per course, max 6 courses | Check the BAUET guide | B+ cap on improvement |
The row that matters most is the re-examination grade. At BAIUST you keep the grade you earn in a re-examination, with no cap. At BAUST the grade is capped. If you are reading a BAUST rule and applying it to BAIUST, you are underestimating what a good re-examination can do for your CGPA.

Common Mistakes BAIUST Students Make
Assuming the referred exam is capped. It is not. BAIUST lets you earn the full grade in a re-examination. Students who sit a referred exam half-heartedly because they think the best they can get is a B are leaving grade points on the table.
Treating an F as a number in the average. An F is 0.00, but the real cost is not the zero. It is the missing credit and the ladder it triggers: referred exam, then backlog, then retake, then possibly a term repeat. Clear an F immediately. Every term you delay it, the ladder gets longer.
Missing the improvement window. Improvement is allowed only within the next three consecutive semesters, once per course, and only six courses in the whole degree. A B from your first year cannot be improved in your fourth year.
Forgetting the mentor’s recommendation. Referred exams, backlog exams, improvement exams and withdrawals all require the recommendation of your mentor or student advisor. Students who skip that step find their application is not processed, and the term moves on without them.
Confusing 2.00 with safety. A 2.00 CGPA may be the quoted graduation minimum, but two consecutive levels below 2.25 ends the programme. If your CGPA is sitting between 2.00 and 2.25, you are not safe. You are one level away from withdrawal.
Averaging grade points without credits. A plain average of your grades is not your GPA. The 3-credit courses count three times as much as the 1-credit ones. Always multiply by credits first, then divide by total credits.
Tips to Keep Your BAIUST CGPA High
Protect the 40% attendance line. Missing more than 40% of classes without approval cancels your term registration. The grade you lose is not the problem. The lost term is.
Attack referred exams at full effort. Because the grade is uncapped, a referred exam is the cheapest CGPA repair available to you. A failed 3-credit course cleared at A- returns 10.50 points. The same course cleared at a capped B would return only 9.00.
Spend your six improvement slots on 3-credit courses at B or B-. Improving a 3-credit B to an A- gains 0.75 points. Improving a 1-credit course gains a quarter of that. Save the slots for the heavy courses.
Run the target calculation before every term. If you want a 3.50 CGPA after next term, work out the exact term GPA you need, then work out which courses must hit which grades to get there. Students who do this stop being surprised by their results.
Keep the mentor in the loop early. Every re-examination, backlog, improvement and withdrawal needs the mentor’s recommendation. A mentor who hears about a problem in week two can help. A mentor who hears about it after the deadline cannot.
Frequently Asked Questions
What is the grading system of BAIUST?
BAIUST uses the UGC uniform 4.00 scale: A+ 4.00 for 80% and above, A 3.75, A- 3.50, B+ 3.25, B 3.00, B- 2.75, C+ 2.50, C 2.25, D 2.00 for 40-44%, and F 0.00 below 40%. D is the minimum passing grade.
What CGPA do I need to graduate from BAIUST?
The commonly quoted minimum is a CGPA of 2.00. But BAIUST’s own policy withdraws a student who fails to reach a CGPA of 2.25 in two consecutive levels, so 2.25 is the practical floor. Aim comfortably above it, and confirm the graduation figure in your current department handbook.
I failed one course. Do I have to repeat the term?
No. If you fail one or two theoretical courses, you are promoted and you sit a referred examination at the end of the term. You keep the grade you earn, with no cap. You only repeat the term if you fail three or more theoretical courses.
Can I improve a B grade at BAIUST?
Yes. If you obtain a grade of B or below, you can sit an improvement re-examination once for that course, within the next three consecutive semesters. You can do this for a maximum of six courses in a four-year programme, and the better grade counts.
What happens if I fail the referred exam?
The course becomes a backlog course. You get one re-examination chance in the following term, and you must clear it then. If you do not, you have to retake the course in a subsequent semester, registering through IUMSS like a new course.
Is there an official BAIUST CGPA calculator?
No. BAIUST does not publish an official calculator. Use the homepage calculator on cgpacalculatorpro.com, which runs on the same UGC 4.00 scale, and check the result against the worked examples in this guide.
What CGPA earns honours or a gold medal at BAIUST?
A degree with honours needs an overall CGPA of 3.75 or better. The gold medal goes to students finishing with a CGPA of 4.00, and to the first position holder in each department with a minimum CGPA of 3.80. The VC’s List and Dean’s List are also awarded on whole-programme CGPA, but their exact thresholds are not published in readable form, so ask the Controller of Examinations.
Conclusion
BAIUST’s grading system is the familiar UGC 4.00 scale on the surface, and a distinct set of rules underneath. The scale decides what each mark is worth. The rules decide what happens when things go wrong, and at BAIUST those rules are unusually detailed: an uncapped referred examination, a one-chance backlog system, a term repeat with exemption carry-forward, a six-course improvement allowance, and a 2.25 withdrawal line that is stricter than the quoted graduation minimum. Learn the scale in your first week and the ladder in your first term, and you will never be surprised by a result sheet.
