Quick answer
If you study at International Standard University in Dhaka, this guide explains the international standard university grading system in full, with the university’s own published table, its marks split, and worked examples you can check line by line. ISU grades on a 4.00 scale. An A+ is worth 4.00 and needs 80 percent or above, an A is 3.75 for 75 to below 80 percent, an A- is 3.50 for 70 to below 75 percent, and the scale runs down through B+, B, B-, C+, C and D (2.00 for 40 to below 45 percent) to F (0.00 for below 40 percent). Your course mark is built from class attendance and participation (10 marks), class tests (10), assignment and presentation (10), the semester midterm (20) and the semester final (50), for a total of 100. Your semester GPA is the credit-weighted average of your grade points, and your CGPA is the same calculation across every completed semester.
Two warnings belong right at the top. First, ISU publishes two different graduation floors that do not agree: the general rules say a minimum CGPA of 2.00, while the BBA, CSE, Textile Engineering and BA in English programme pages each require 2.50. Until the Registrar confirms which floor governs your programme, plan to 2.50, so either version leaves you safe. Second, no dedicated ISU Dhaka grading guide could be found anywhere else on the web: search results are dominated by Iowa State University and Illinois State University, both also called ISU, and by calculators built for those American universities. Do not use an American ISU scale for a Dhaka transcript.
ISU is a private university in Mohakhali, Dhaka, approved by the University Grants Commission (UGC) under the Private University Act 2010. It was established on 3 June 2018 and began operating the following year from the Civil Engineers Bhaban at 69 Mohakhali C/A, Dhaka-1212, where its campus still sits. The university is run by the International Standard University Trust, backed by Standard Group, and its Vice-Chancellor is Professor Dr Abdul Awal Khan. It now runs five faculties and eight departments, including Business Studies (BBA, MBA), Engineering and Technology (CSE, Textile Engineering, Apparel Merchandising and Management), Humanities and Social Sciences (BA Hons in English, MA in English Literature and Cultural Studies, LLB Hons), Advanced Science and Computing and Health Sciences. Programme credit totals differ a lot: the BBA requires 132.0 credits, BA Hons in English requires 141.0, the LLB requires 140, CSE requires 154.0, and Textile Engineering requires 162.0. Check your own programme page for your total.
First, make sure you have the right ISU
The letters ISU are a genuine search trap, and it is the single most common reason students land on the wrong grading table. Three universities share the initials, and their scales are not interchangeable. International Standard University, Dhaka, Bangladesh, is the subject of this guide: a UGC-approved private university on a 4.00 scale where A is 3.75 and A+ is 4.00. Iowa State University, in Ames, Iowa, USA, is a large American public university whose scale gives A 4.00, A- 3.67, B+ 3.33, B 3.00, B- 2.67, C+ 2.33, C 2.00, C- 1.67, D+ 1.33, D 1.00, D- 0.67 and F 0.00. If you applied the Iowa scale to a Dhaka result, an A- worth 3.50 at ISU Dhaka would be scored as 3.67, and a B- worth 2.75 would be scored as 2.67, so every GPA you calculated would be wrong in both directions. Illinois State University, in Normal, Illinois, USA, is a third ISU, also on a 4.0 scale but with its own plus and minus values and its own academic-standing rules. A fourth near-miss is Sylhet International University, also in Bangladesh, which shares the word International in its name but is a different institution in a different city, and it has its own grading guide. Whenever a page or calculator says ISU without naming city and country, stop and check: Ames, Cyclones, Normal or Redbirds means it is not your university. Mohakhali, Dhaka, the UGC and A at 3.75 means it is.
Check your ISU GPA with the calculator
There is no dedicated calculator page for ISU on this site, and this guide will not pretend otherwise. Use the site homepage calculator with the UGC-scale values from the table below, exactly the values ISU publishes in its own academic rules. Open the CGPA calculator homepage and work through your courses one by one. For each course, enter the credit hours from your programme sheet (most ISU theory courses carry 3 or 4 credits) and select the letter grade earned. The calculator converts each letter to ISU’s grade point, multiplies by credits, adds those products, and divides by total credits. The worked examples below let you verify it against hand arithmetic first.
Follow these steps for a semester GPA. First, list every course you completed that semester, including any course you failed, with credit hours from your registration record, not from memory. Second, convert each final mark to a letter using ISU’s table, not a school or HSC table: at university level 80 percent is an A+, while SSC and HSC marks sat on a different 5.00 scale, and the two must never be mixed. Third, multiply each grade point by that course’s credits. Fourth, add all the products. Fifth, divide by the total credits, rounding only at the very end to two decimal places, as ISU’s own worked example does. For a CGPA, repeat the same steps across all completed semesters, or weight each semester GPA by its credits and divide by total credits, as shown below. If your result differs from your transcript by more than 0.01, the usual causes are a wrong credit value, a missed F course, or an improvement grade not yet processed.
ISU’s official grading table
ISU does publish its own grade table, in Section 20 of its Academic Rules and Regulations on the official site. The table is presented there as an image rather than searchable text, which is probably why many students believe no table exists: a text search finds nothing, but the table is there, and its bands and points are identical to the UGC uniform scale. Here it is, transcribed exactly:
| Numerical grade | Letter grade | Grade point |
|---|---|---|
| 80% or above | A+ | 4.00 |
| 75% to less than 80% | A | 3.75 |
| 70% to less than 75% | A- | 3.50 |
| 65% to less than 70% | B+ | 3.25 |
| 60% to less than 65% | B | 3.00 |
| 55% to less than 60% | B- | 2.75 |
| 50% to less than 55% | C+ | 2.50 |
| 45% to less than 50% | C | 2.25 |
| 40% to less than 45% | D | 2.00 |
| Less than 40% | F | 0.00 |
Read the bands carefully, because boundaries are where marks change value. Exactly 80 percent is an A+, but 79 percent is an A, and that single mark is worth 0.25 grade points per credit, or 0.75 points on a 3-credit course. Exactly 75 percent is an A, not an A-, and exactly 70 percent is an A-, not a B+. The lowest passing grade is D at 2.00: a student who earns a minimum D is credited and promoted in that course, so D passes, even though it drags a GPA down hard. Below 40 percent is an F at 0.00, which must be dealt with through the re-sit or retake route below.
The same section gives the marks split for a theory course, also as an image. The final examination is only half the course:
| Component | Marks |
|---|---|
| Class attendance and participation | 10 |
| Class tests | 10 |
| Assignment and presentation | 10 |
| Semester midterm | 20 |
| Semester final | 50 |
| Total | 100 |
Put numbers on that split and the strategy becomes obvious. A student who scores 9 out of 10 for attendance and participation, 8 out of 10 in class tests, 9 out of 10 for assignment and presentation, 16 out of 20 in the midterm and 38 out of 50 in the final has 9 + 8 + 9 + 16 + 38 = 80, exactly the A+ boundary. Conversely, a student who scores a strong 44 out of 50 in the final but only 4, 4 and 5 out of 10 in the coursework components plus 12 out of 20 in the midterm has 4 + 4 + 5 + 12 + 44 = 69, a B+, not the A the final alone seemed to promise. The 30 coursework marks and the 20 midterm marks are decided before the final week, and they are the cheapest grade points in the degree. ISU’s rules also record three status grades that are not grade points: I for an incomplete course, AB for absence in the final examination, and E for expulsion from a midterm or final examination. GPA is computed without those grades: an AB course contributes no points and no credits to that semester’s GPA until resolved, but it does not vanish from your record.
ISU’s own worked example, printed in the same section, is a useful check. Five courses with credits 3, 3, 3, 2 and 1 and grades A+, B, A, B+ and A- give 3 x 4.00 + 3 x 3.00 + 3 x 3.75 + 2 x 3.25 + 1 x 3.50 = 12.00 + 9.00 + 11.25 + 6.50 + 3.50 = 42.25 points over 12 credits, and 42.25 / 12 = 3.5208, reported as 3.52. If your hand calculation reproduces 3.52, your method is right; if not, re-check the credits first.
Cross-checking matters here, because ISU’s table is not an outlier. The identical bands and points appear in the published grading tables of other Bangladeshi universities, including the International Islamic University Chittagong academic system page and the Islamic University of Technology assessment and grading page, both of which print the same UGC uniform scale. When three independent published tables agree to the mark, and ISU’s own rules image agrees with them, you can use the table with confidence. The trap to avoid is the other direction: some well-known private universities use a different scale entirely, with A at 4.00 for 90 percent or above, and students who borrow a friend’s calculator settings from one of those universities will miscalculate every ISU result.
What ISU has not published online: the unverified box
The following points could not be verified from ISU’s own published pages at the time of writing, and they are presented as open questions with the peer norm alongside, never as ISU facts. If any of them decides your next semester, confirm it in writing with the Registrar before you act: Mohakhali campus, 69 Mohakhali C/A, Dhaka-1212, email info@isu.ac.bd, phones 01313-037070, 01313-037071, 01313-037078 and 01313-400600.
- The graduation floor conflict (2.00 versus 2.50). Both figures are published by ISU itself, in different places: Section 15 of the general rules requires a minimum CGPA of 2.00, while the BBA, CSE, Textile Engineering and BA in English programme pages each require 2.50, and the LLB page requires 2.00. What is unverified is which document wins for a given student. Peer norm: several Bangladeshi private universities set the programme floor at 2.50 even where a general rule mentions 2.00, and the safe plan is to treat 2.50 as your target until the Registrar confirms otherwise.
- Attendance below 70 percent. Section 3 of the rules is explicit that at least 80 percent attendance is required to sit final examinations, and that students with 70 percent to below 80 percent may sit them with a fine of Tk. 500 per course. It states no route for attendance below 70 percent. Whether such a student is barred outright, must repeat the course, or may appeal on medical grounds is not published. Do not assume a fine will fix attendance below 70 percent.
- How an F counts in the GPA denominator. ISU’s formula divides by total credit hours completed, and GPA is computed without I, AB and E grades, but the rules do not spell out whether a failed course’s credits stay in the denominator. The F-cost example below states its assumption openly: it counts the failed course’s credits in the denominator, the standard credit-weighted treatment.
- GPA rounding. ISU’s own example rounds 3.5208 to 3.52, but no rounding rule is published in text. Differences of 0.01 between a calculator and a transcript are usually rounding, not error.
- Practical and sessional mark splits. The published 10-10-10-20-50 split is stated for theory courses, but no separate split for laboratory or sessional work is published. Lab-heavy CSE and Textile students should confirm their department’s split at the start of the semester.
- Programme totals for newer programmes. Credit totals and graduation floors for the BSc in Artificial Intelligence and Data Science, MBA, MA in English and Master of Public Health are not all stated on the programme pages checked. Use the totals quoted here only for the five programmes named.
Step-by-step calculation
Work in this order. Step one: write down every course from the semester, with credit hours from your registration slip. Include failed courses, and keep I, AB and E courses on a separate line, because ISU computes GPA without those status grades. Step two: turn each final mark out of 100 into a letter with ISU’s table, using the exact boundaries: 80 is A+, 79 is A, 75 is A, 74 is A-, 70 is A-, 69 is B+, 65 is B+, 64 is B, 60 is B, 59 is B-, 55 is B-, 54 is C+, 50 is C+, 49 is C, 45 is C, 44 is D, 40 is D, 39 is F. Step three: multiply each grade point by the course’s credits. Step four: add all the grade points, and separately add all the credits. Step five: divide total grade points by total credits, rounding to two decimal places only at the end. Never average grade points without weighting by credits, and never average percentages and then convert.
For a CGPA, pool every completed course from every semester, multiply, add, divide. The shortcut is identical: multiply each semester GPA by that semester’s credits, add those products, and divide by total credits. Use unrounded semester GPAs where you have them, because rounding each semester first can shift the CGPA by 0.01 or 0.02, enough to matter at a scholarship or graduation boundary.
The formula
ISU prints its formula as GPA equals the sum of (credit hours x grade point) divided by the sum of credit hours. In plain form:
Semester GPA = (sum of grade point x credits for each course) / (total credits)
CGPA = (sum of grade point x credits for every completed course) / (total credits completed)
Equivalently, CGPA = (sum of semester GPA x semester credits) / (total credits). Both forms give the same answer, and the second is the one to use when you only have semester GPAs. Credits are the weights: a 4-credit core course moves your GPA more than a 1-credit lab or viva.
Worked example: a semester GPA of exactly 3.50
Take a realistic ISU semester of five 3-credit courses, 15 credits in total, with grades A+, A, A-, B+ and B. The arithmetic, course by course, is:
| Course | Grade | Grade point | Credits | Grade points |
|---|---|---|---|---|
| Course 1 | A+ | 4.00 | 3 | 12.00 |
| Course 2 | A | 3.75 | 3 | 11.25 |
| Course 3 | A- | 3.50 | 3 | 10.50 |
| Course 4 | B+ | 3.25 | 3 | 9.75 |
| Course 5 | B | 3.00 | 3 | 9.00 |
| Total | 15 | 52.50 |
Semester GPA = 52.50 / 15 = 3.50. A 3.50 semester does not require straight A grades: with equal credits, the simple average of the five grade points (4.00 + 3.75 + 3.50 + 3.25 + 3.00 = 17.50, and 17.50 / 5 = 3.50) agrees with the weighted result. That agreement only holds when every course carries the same credits. Change Course 1 to 4 credits and Course 5 to 2 credits, keeping the same grades, and the total becomes 16.00 + 11.25 + 10.50 + 9.75 + 6.00 = 53.50 over 15 credits, giving 53.50 / 15 = 3.5667, or 3.57. Same grades, different GPA, purely because the credits moved.
Worked example: CGPA across semesters
Suppose the student above follows that 3.50 semester (15 credits, 52.50 points) with a second semester of 15 credits at a lower GPA, and suppose the two semesters together sit on top of earlier work. The cleanest CGPA illustration uses semester totals. Say a student has already completed 30 credits with a CGPA of 3.20, which represents 30 x 3.20 = 96.00 grade points. The student then completes the 15-credit semester from the previous example, adding 52.50 points. The new totals are 96.00 + 52.50 = 148.50 points over 30 + 15 = 45 credits, and CGPA = 148.50 / 45 = 3.30. The new semester at 3.50 pulled the CGPA up from 3.20 to 3.30, but only by 0.10, because it is only one third of the total credits. A student with 90 credits at 3.20 (288.00 points) who scores 3.50 in a 15-credit semester moves to (288.00 + 52.50) / 105 = 340.50 / 105 = 3.2429, or 3.24, a gain of only 0.04. The earlier you fix a weak semester through a legitimate re-sit or improvement, the more it is worth.
What one F costs
Take the same 3.50 semester and change only Course 5 from a B to an F. Course 5 now contributes 3 x 0.00 = 0.00 instead of 9.00, so the total falls from 52.50 to 43.50, and the GPA becomes 43.50 / 15 = 2.90. One failed 3-credit course in a 15-credit semester costs 0.60 of GPA, dropping 3.50 to 2.90, below the 3.00 line many employers and scholarship panels use as a first filter. The same F also counts toward promotion: a student who fails more than three courses is not promoted to the next semester.
ISU gives a failed course two distinct routes back, and confusing them is costly. The first is the re-sit examination under Section 19: for an F grade, a student may re-sit two weeks after the commencement of the following semester. The re-sit carries 50 marks, equal to the usual final allocation, and continuous-assessment and midterm marks remain unchanged. The student must apply to the Controller of Examinations through the department Chairperson within one week of the publication of final results, and the fee is Tk. 2000 per course, for a maximum of three F courses. If the student fails the re-sit, they must re-register the course within the next two consecutive semesters. The second route is the retake and improvement policy under Section 14: a student may repeat a course once, for improvement of any grade up to A-, within the next two consecutive semesters, with written permission from the Chairperson and a copy to the Controller within seven days of publication of results. The better grade is accepted, the previous grade is marked R (repeated) and excluded from GPA computation, and registration carries no waiver. A student who already holds an A or A+ cannot improve that course. Dismissal is the hard edge: semester GPA below 2.00 for two consecutive semesters, or failing a particular course up to the fourth attempt, or admission on fake information or breach of regulations.
Target planner: what average do you actually need next semester?
Do the arithmetic instead of aiming vaguely for “all A grades”. Multiply your current credits by your current CGPA to get your current points, multiply your planned total credits by your target CGPA to get the points you will need, subtract to find the points the next semester must supply, and divide by the next semester’s credits. Suppose you have completed 60 credits with a CGPA of 3.20, which is 60 x 3.20 = 192.00 points. You want 3.30 after one more 15-credit semester, a total of 75 credits. You will need 75 x 3.30 = 247.50 points, so the next semester must supply 247.50 – 192.00 = 55.50 points, and 55.50 / 15 = 3.70, a demanding but achievable mix of A and A- grades: three A grades plus two A- grades give 33.75 + 21.00 = 54.75 points, slightly short, so one A- would need to rise to an A. Now test the limit: straight A+ grades give 15 x 4.00 = 60.00 points, for (192.00 + 60.00) / 75 = 252.00 / 75 = 3.36. So from 3.20 on 60 credits, no single 15-credit semester can reach 3.50. Two 15-credit semesters at 3.70 give (192.00 + 55.50 + 55.50) / 90 = 303.00 / 90 = 3.3667, or 3.37, still short of 3.50. Recovery to 3.50 from 3.20 takes more than two strong semesters, which is why improvement work should start in the very next window.
GPA vs CGPA: the distinction that decides scholarships and jobs
Semester GPA describes one semester only; CGPA describes your whole degree so far. Employers, BCS guidance quoted on ISU’s own English programme page, and scholarship panels almost always ask for the CGPA, not the best single semester: the English page notes that a student who passes with a CGPA of 3.0 or above has a fair chance to qualify for BCS and other competitive jobs. A single brilliant semester does not erase a weak first year, and a single weak semester does not ruin a strong record, because the CGPA weights every credit equally across time. Two further distinctions matter. First, the SSC and HSC GPA on a 5.00 scale is a different instrument from the university CGPA on a 4.00 scale: never convert one to the other by multiplying by 4/5; report each on its own scale. Second, a transcript CGPA and a calculator CGPA can differ by 0.01 or 0.02 for legitimate reasons: rounding, an R-marked improvement not yet processed, or an I, AB or E course excluded from the calculation. If the gap is larger than 0.02, something structural is wrong, usually credits or a missed course, and the Controller of Examinations is the place to resolve it.
For comparison, the same UGC 4.00 scale and credit-weighted method appear in the other guides in this series: the UITS grading guide and the UCTC grading guide use the same national reference scale, while the RSTU grading guide shows how another university’s attendance and retake detail differs even when the grade points match. The scale travels; the local rules do not.
Common mistakes ISU students make
- Using an American ISU scale. Iowa State’s A- is 3.67 and its B+ is 3.33; ISU Dhaka’s A- is 3.50 and its B+ is 3.25. A transcript built on the wrong scale will not match the university’s record.
- Mixing the 5.00 school scale with the 4.00 university scale. An HSC GPA of 5.00 is not a university CGPA of 4.00 by conversion, and an admission requirement quoted as a combined SSC and HSC CGPA of 6.00 (as on the LLB page) is a school-scale figure, not a university CGPA. Keep the scales in separate columns.
- Averaging grades instead of weighting by credits. Grades do not average to their simple mean unless every course carries the same credits. A 4-credit A+ and a 2-credit C give (16.00 + 4.50) / 6 = 20.50 / 6 = 3.4167, or 3.42, not the simple mean of 3.13. Only the credit-weighted answer is used.
- Ignoring the 30 coursework marks and the 20 midterm marks. Students who treat the final as the whole course throw away half the marks before the final week. The attendance, tests, assignment and midterm components are the most controllable marks in the degree.
- Missing the seven-day and one-week windows. Improvement permission must reach the Controller of Examinations within seven days of the publication of results, and a re-sit application must be made within one week of the publication of final results. Both clocks run from publication, not from when you happen to read the result. A day late can cost a whole semester.
- Assuming an F disappears. An F contributes 0.00 points and, on the treatment used in this guide’s example, keeps its credits in the denominator until resolved through the re-sit or retake route. It also counts toward the promotion bar and the fourth-attempt dismissal rule. Deal with an F in the next window, not in the final year.
- Treating 2.00 as safe for every programme. The general rules say 2.00, but four programme pages say 2.50. A BBA, CSE, Textile or English student who plans to 2.00 and stops there may graduate under one document and fail under the other. Plan to 2.50.
- Forgetting the attendance fine trap. Attendance of 70 percent to below 80 percent is not free: it costs Tk. 500 per course to sit the final, and the rules publish no paid route below 70 percent at all. Attendance is a grade input (10 marks) and a gate to the examination, twice over.
Tips that actually move an ISU CGPA
Protect the attendance marks first: they are 10 percent of every theory course and the gate to the final examination. At 80 percent you sit the final with no fine; at 70 to below 80 percent you pay Tk. 500 per course; below 70 percent the published rules offer no route, so treat 80 percent as your floor. Treat class tests and assignments as seriously as the midterm: together they are 20 marks, the same weight as the midterm. A student with full coursework and midterm marks (50 out of 50) needs only 30 out of 50 in the final to reach 80 and an A+, while a student with 30 out of 50 before the final needs a perfect 50.
Use ISU’s deadlines as a calendar. Diary the result-publication date the day results appear, because the seven-day improvement window and the one-week re-sit window both run from it. Improvement is capped: only grades up to A-, only once per course, only within the next two consecutive semesters, with the better grade replacing the old one and the old grade marked R. If you hold an F, apply for the re-sit within the week, pay Tk. 2000 per course, and note that the re-sit covers only the 50 final marks while coursework and midterm marks stand. If you believe a script was mis-marked, re-evaluation is a written application to the Controller within seven days of publication, at Tk. 1000 per course, non-refundable. And note the merit-scholarship line: semester scholarships for first, second and third positions on GPA (ties broken by total marks percentage, then the fourth digit of GPA, then SSC and HSC results) require a full load of 15 credit hours, a class of at least 10, and a minimum GPA of 3.50. At ISU, 3.50 is the published scholarship threshold, which is another reason the worked example here lands exactly there.
Finally, verify your record every semester against the transcript, not a calculator alone. Check that improvement grades show the new grade with the old one marked R and excluded, that I, AB and E courses are absent from the GPA computation, and that your credit total matches your programme requirement (132 for BBA, 141 for English, 140 for LLB, 154 for CSE, 162 for Textile). Raise any difference with your Chairperson and the Controller promptly, while the windows are still open.
Frequently asked questions
Which ISU does this guide cover?
International Standard University, Dhaka, Bangladesh, at Mohakhali, approved by the UGC. It does not cover Iowa State University in Ames, Iowa, or Illinois State University in Normal, Illinois, which publish different scales, nor Sylhet International University, a different Bangladeshi institution. If a source mentions Ames, Cyclones, Normal or Redbirds, it is not your university.
What is ISU’s grading scale?
ISU’s own published scale, identical to the UGC uniform scale, is A+ 4.00 (80 percent or above), A 3.75 (75 to below 80 percent), A- 3.50 (70 to below 75 percent), B+ 3.25 (65 to below 70 percent), B 3.00 (60 to below 65 percent), B- 2.75 (55 to below 60 percent), C+ 2.50 (50 to below 55 percent), C 2.25 (45 to below 50 percent), D 2.00 (40 to below 45 percent) and F 0.00 (below 40 percent). D is the lowest passing grade.
Is the graduation CGPA 2.00 or 2.50?
Both figures are published by ISU. The general rules require 2.00, while the BBA, CSE, Textile Engineering and BA in English programme pages each require 2.50, and the LLB page requires 2.00. Until the Registrar confirms which document governs your programme, treat 2.50 as your target: it satisfies either version. The Registrar’s contact details are in the unverified box above.
How much attendance do I need to sit the final examination?
At least 80 percent attendance is required. Students with 70 percent to below 80 percent may sit the final with a fine of Tk. 500 per course. The published rules state no route below 70 percent, so do not plan on one. Attendance also contributes 10 of the 100 marks in every theory course.
What happens if I fail a course?
An F is worth 0.00 grade points. ISU offers a re-sit two weeks after the commencement of the following semester, covering the 50 final marks, with coursework and midterm marks unchanged; apply within one week of publication of final results and pay Tk. 2000 per course, for a maximum of three F courses. If you fail the re-sit, re-register the course within the next two consecutive semesters. Separately, the improvement policy lets you repeat a course once, for grades up to A-, within the next two consecutive semesters, with the better grade counting and the old grade marked R. Failing more than three courses blocks promotion, and failing a course up to the fourth attempt is a ground for dismissal.
Can I improve a grade I already passed?
Yes, within limits. You may repeat a course once for improvement of any grade up to A-, within the next two consecutive semesters, with written permission from your department Chairperson and a copy to the Controller of Examinations within seven days of the publication of results. The better grade is accepted and the previous grade is marked R and excluded from GPA computation. You cannot improve an A or A+ under this policy, and registration for the repeat carries no waiver.
How do I convert my ISU CGPA for applications abroad?
Report your CGPA on its own 4.00 scale with the ISU grading key attached to your transcript, and do not convert it by formula. Foreign universities and credential evaluators read the original letter grades and marks against their own tables; a home-made conversion will misstate your record. If a form forces a 4.0 entry, enter your ISU CGPA as printed, and attach the grading key so the reader can see that your A is 3.75 and your A+ is 4.00. See also the SIU grading guide and the FIU grading guide.
Conclusion
ISU’s system rewards students who understand its weights and its windows. The grade table is the national UGC scale, published by ISU itself, and the marks split gives you 50 marks before the final examination even begins: coursework, tests, assignments and the midterm are half of the grade, not preparation for it. The worked examples give you three anchors to test any calculator against: a 15-credit semester of A+, A, A-, B+ and B gives 52.50 / 15 = 3.50; a 30-credit record at 3.20 plus that semester gives 148.50 / 45 = 3.30; and a single F in that semester drops it to 43.50 / 15 = 2.90. The risks are equally concrete: attendance below 80 percent costs money or the examination itself, improvement and re-sit windows close seven days and one week after results, more than three failures block promotion, and the graduation floor is ambiguous between 2.00 and 2.50, so plan to the higher figure. Work the numbers every semester, and confirm anything marked unverified with the Registrar before it becomes urgent.
