Notre Dame University Bangladesh Grading System 2026: GPA & CGPA Guide

Quick answer: how NDUB grades work

Notre Dame University Bangladesh (NDUB) grades on a 4.00 scale that matches the University Grants Commission (UGC) uniform scale used across Bangladeshi universities: 80% and above is an A+ worth 4.00, 75% is an A worth 3.75, and the scale runs down through A- (3.50), B+ (3.25), B (3.00), B- (2.75), C+ (2.50), C (2.25) and D (2.00), 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 same calculation stretched across every semester you have completed. D is a pass, not a fail. But passing every course is not the same as graduating: NDUB’s UGC-reviewed LLB curriculum sets the minimum CGPA for graduation at 2.50, and the scholarship rules add a second, higher bar of 3.00. This guide gives you the official table, the exact formulas, three hand-checked worked examples, and the retake, waiver, supplementary-exam and attendance rules that no other NDUB guide collects in one place. Where NDUB does not publish a rule, we say so plainly instead of inventing one.

First, make sure you mean the right “Notre Dame”

Three different institutions share this name, and search engines mix them up constantly. This guide is about only one of them:

• Notre Dame University Bangladesh (NDUB), Dhaka – this guide. A private, non-profit, Catholic university in Motijheel, Dhaka, founded by the Congregation of Holy Cross, government approval 29 April 2013, classes from fall 2014. Official site: ndub.edu.bd. Uses the UGC Bangladesh 4.00 scale in this article.
• University of Notre Dame, Indiana, USA – a completely different university in another country. Its Registrar scale is A 4.000, A- 3.667, B+ 3.333, B- 2.667, C+ 2.333, C- 1.667, D 1.000. It has no A+ grade and no 3.75 or 3.50 values. If you use an American “Notre Dame GPA calculator” for NDUB courses, every grade except B and F comes out wrong.
• Notre Dame College, Dhaka – the famous boys’ college in Motijheel, run by the same Congregation of Holy Cross. It teaches classes 11 and 12 (Higher Secondary), not university degrees, and its results run on the SSC/HSC 5.00 scale, not the university 4.00 scale. Its students are not NDUB students, and NDUB’s grading rules do not apply to them.

A useful identity check: if the page you are reading does not end in ndub.edu.bd, and does not mention Motijheel and the UGC scale, it is probably about one of the other two. Check the domain before you trust a number.

Check your NDUB GPA with the calculator

The fastest way to check your numbers is the CGPAPro calculator on the homepage. Here is the honest part: there is no separate NDUB calculator page, so use the homepage calculator and select the UGC Bangladesh scale. That scale is identical to NDUB’s official table value for value (A+ 4.00 down to D 2.00, F 0.00), so no conversion is needed and the result matches NDUB’s own arithmetic:

1. Open the CGPAPro GPA calculator and select the UGC Bangladesh grading system.
2. For each course, type its credit hours exactly as they appear on your registration, and choose the letter grade you earned.
3. The calculator multiplies each grade point by its credit hours, adds up the quality points, and divides by total credits. That is your semester GPA.
4. For your CGPA, repeat this for every semester and combine them with the credit-weighted CGPA formula in the worked examples below. Do not average your semester GPAs directly; that shortcut is wrong whenever your semesters carry different credit loads, and Example 2 below proves it with numbers.

One warning before you trust any other online calculator: most generic calculators use the American scale, where A is 4.00 and A- is 3.67. At NDUB, A is 3.75 and A- is 3.50. A calculator that does not let you pick the UGC Bangladesh scale will silently inflate your GPA, and you will only discover the error when the official result sheet disagrees with it.

What NDUB is

NDUB is a private, non-profit, Catholic university located at 2/A, Arambagh, Motijheel, Dhaka 1000. It was founded by the Congregation of Holy Cross and received government approval on 29 April 2013; academic activities began in fall 2014. Its motto is “The Competence to See and the Courage to Act”. The university runs six departments across five faculties: Business Administration, Computer Science and Engineering, English Language and Literature, Economics, Law, and Microbiology (approved by the UGC in June 2024). Programs are UGC-approved, and the academic year runs in three sessions: Spring (January to April), Summer (May to August), and Fall (September to December). Admission to undergraduate programs requires a minimum GPA of 2.5 in both SSC and HSC individually, and graduate admission requires a minimum CGPA of 2.5 out of 4.00 in the bachelor’s degree.

The official NDUB grading table (2026)

NDUB’s own website describes the system in words: a student’s total performance in a course comes from continuous assessment (in-course work, assignments, class attendance and participation) plus a semester final examination, and “a Letter Grade with a specified number of Grade Points is awarded in each course”. Program pages confirm the scale is a “four (4) point grade”. The full letter-grade table with marks bands is published in NDUB’s UGC-reviewed Outcome-Based Curriculum for the LLB program, and it matches the grading-policy table for NDUB published elsewhere band for band. Here it is:

Three things about this table catch students out every year. First, the bands are strict: 79% is an A (3.75), not an A+, and 74% is an A- (3.50), not an A. There is no rounding up into the next band. Second, D is a pass: 40% earns 2.00 and clears the course, though a transcript full of D grades will drag your CGPA toward the 2.50 graduation floor. Third, there is no C- or D+ at NDUB. The scale jumps from C (2.25) straight to D (2.00). If a calculator offers you a “C- 1.75”, that is not NDUB’s scale.

A note on sourcing, because it matters: NDUB’s public website states the four-point system but does not print this letter table as readable text on its main academics pages, so this article takes the table from NDUB’s own UGC-reviewed curriculum document, cross-checked against the published NDUB grading policy. If your department handbook prints a different band for any grade, your handbook wins for your program: confirm it with your department office and treat this table as the university standard, not a substitute for your handbook.

How your 100 marks are built

Before the grade table can touch you, your 100 marks have to be assembled. NDUB’s Microbiology program page publishes the split for a standard course:

• Class attendance: 10 marks
• Presentation: 10 marks
• Assignment or homework: 10 marks
• Quiz or class tests (minimum 2): 10 marks
• Mid-term examination (1 hour): 20 marks
• Final examination (2 hours): 40 marks
• Total: 100 marks

Two pass bars hide inside that split, and students who do not know them get surprised. You need 40% of the 40 in-course marks (that is, 16 marks from attendance, presentation, assignment and quizzes) to pass the in-course part, and 40% of the 60 mid-term plus final marks (that is, 24 marks) to pass the exam part. In other words, the final exam is only 40% of your grade. A student who ignores everything until finals week is defending 40 marks while 60 are already decided. Sessional (lab and practical) courses are assessed differently: by observation of your classwork and by viva-voce.

How to calculate your NDUB GPA, step by step

NDUB’s curriculum document defines GPA as the weighted average of grade points over the courses passed or completed in a semester. Follow these steps:

1. List every course with its credit hours and your letter grade.
2. Convert each letter grade to its grade point using the official table above.
3. Multiply each grade point by the course’s credit hours. This is the course’s quality points. A 3-credit A (3.75) gives 3 x 3.75 = 11.25 quality points.
4. Add up all the quality points.
5. Add up all the credit hours.
6. Divide total quality points by total credits. Round to two decimals. That is your semester GPA.

Semester GPA = sum of (grade point x credit hours) / sum of credit hours

CGPA = total quality points across all semesters / total credit hours across all semesters

The second formula is the important one. Your CGPA is not the average of your semester GPAs. It is the credit-weighted total. A 19-credit semester counts more than a 15-credit one, and Example 2 shows the difference in hard numbers.

Worked example 1: one semester’s GPA (3.50)

Take a first-semester BBA-style load: five courses, 3 credits each. Every number here is checked by hand:

GPA = 52.50 / 15 = 3.50 exactly. Notice what decided it: the A+ in Computer Fundamentals contributed 12.00 points while the B in English Composition contributed only 9.00, a 3.00-point swing from one course. When every course carries the same credits, the GPA is just the average of the grade points, but that is a coincidence of equal credits, not the rule. The rule is always credit-weighted, and Example 3 shows why that matters.

Worked example 2: CGPA across two semesters (3.36)

Now add a second, slightly weaker semester of 16 credits:

Second semester GPA = 51.75 / 16 = 3.234375, which rounds to 3.23. Now the true CGPA: total quality points 52.50 + 51.75 = 104.25 over total credits 15 + 16 = 31. CGPA = 104.25 / 31 = 3.3629, which rounds to 3.36.

Now watch the trap. If you average the two semester GPAs directly, you get (3.50 + 3.23) / 2 = 3.365, which rounds to 3.37. That is wrong: the true CGPA is 3.36. The simple average overweights the lighter 15-credit semester and underweights the heavier 16-credit one. The gap is small here and grows whenever your semesters carry very different loads, for example a 12-credit semester next to a 19-credit one. Weight by credits, always.

The same arithmetic answers the question every NDUB student asks after a weak semester: what average do I need next semester to reach a target? Suppose the student above wants a CGPA of 3.50 after one more 16-credit semester. Target total points = 3.50 x (31 + 16) = 3.50 x 47 = 164.50. Points already banked = 104.25. Points still needed = 164.50 – 104.25 = 60.25 over 16 credits, which is 60.25 / 16 = 3.7656, so an average of about 3.77 next semester. That is a concrete plan, not a vague “study harder”: roughly an A- average across the whole next semester, with no grade below B+ in a heavy course.

Worked example 3: what a retake repair is actually worth (3.10 to 3.40)

Take a student with four courses totalling 10 credits:

GPA = 31.00 / 10 = 3.10. Now the student retakes the 3-credit core course and improves the C to a B+ (3.25). NDUB’s rule is that the best grade of a course counts for CGPA, so the course now contributes 3 x 3.25 = 9.75 instead of 6.75. New total = 31.00 – 6.75 + 9.75 = 34.00 over the same 10 credits. New GPA = 34.00 / 10 = 3.40. One 3-credit repair moved the GPA by 0.30. But read the price tag in the retake section below before you celebrate: that same retake disqualifies the student from any tuition waiver in the following semester, and the waiver decision would still use the original C grade even if waivers were available. A retake is a CGPA tool, not a free lunch.

GPA vs CGPA: what each number actually does at NDUB

Your semester GPA measures one term. Your CGPA measures your whole degree so far. At NDUB the two numbers pull different levers:

• Semester GPA decides your merit waiver for the following semester. The published tiers (which vary by program) reward a single strong semester: for MBA, EMBA and M.Sc. CSE students, a 4.00 earns a 30% tuition waiver, 3.94 to 3.99 earns 22%, and 3.88 to 3.93 earns 15%, each for one following semester. LLM and ELT students have lower bands: 30% at 3.80 and above, 22% at 3.75 to 3.79, 15% at 3.70 to 3.74.
• CGPA decides scholarship eligibility in general (minimum 3.00 on the 4.00 scale, or the waiver is revoked) and, per the LLB curriculum document, graduation itself (minimum 2.50). Graduate admission elsewhere also reads your CGPA: NDUB itself requires a 2.5 CGPA for entry to its own graduate programs.
• CGPA moves slowly once you have banked many credits. After 31 credits at 3.36, one more 16-credit semester at a perfect 4.00 would give (104.25 + 64.00) / 47 = 168.25 / 47 = 3.58. Even perfection moves the number by only 0.22. Early semesters are where a CGPA is made; late semesters are where it is defended.

Retakes, improvement, incomplete, supplementary exams, and withdrawal

This is the section no generic calculator page gives you, and at NDUB every line of it is published. Read it before you need it:

• Failed course (F): retake is mandatory. A student who gets an F in the semester final must retake the course, and should contact the Registrar’s office immediately after results so arrangements can be made. A course may be registered as many times as wished within the stipulated six-year completion window; from the second registration it counts as a retake. For CGPA, the best grade of the course is counted. An F (or I) grade turns to “R” on retake, and R counts as a neutral grade in the final transcript GPA calculation. But for waiver decisions, the originally obtained grades are used, not the retake grade.
• Grade improvement has a ceiling. You may make up GPA deficiencies in later semesters with better grades, but the improved grade may not exceed 65-69%, which is letter grade B+ (3.25). No matter how well you perform in the improvement attempt, B+ is the cap. And a course that was previously retaken cannot be taken for grade improvement at all. Plan accordingly: you get one repair mechanism per course, not two.
• Incomplete (I) is a countdown, not a pause. An I may be given for genuine reasons if your continuous assessment and mid-term marks are reasonable. You then sit a make-up final in the following semester and the I is replaced by the legitimate grade. If you do not resolve it, the I turns into an F in the next semester, and no I grade appears on your final transcript.
• There is no make-up exam after the semester final. If you miss the final exam for any reason, you repeat the whole course in the following semester with full payment. The only exception NDUB publishes is a sick-bed during finals week for a student who falls sick during the exams. For mid-terms the rule is different: a make-up is possible for serious or valid reasons, but you must bring your parents to meet the Registrar to verify the reason, and you pay Tk. 2,000 per course.
• Supplementary exams are a narrow window, not a general second chance. Only students who secured an F because of low marks (between 15 and 27) in the written part (out of 30 + 40 = 70) are permitted to write a supplementary exam. Only the published list of such students may apply, a student may write supplementary exams for at most two F courses, the rest must be repeated, and the fee is Tk. 4,000 per supplementary exam. If your F came from marks outside that 15-27 window, or you failed three courses, supplementary exams are not your route: retakes are.
• You cannot add or drop courses. NDUB’s curriculum document states that students have no option to add or drop courses from their registration list; departments decide how many courses are offered in each semester. If you are struggling with a load, the route is your student adviser and department chair, not a drop form.
• Semesters can be paused and resumed. A student who drops a semester or multiple semesters for valid reasons may resume with a different batch, and may apply to the Department Chair for total withdrawal from a semester at any time. Note the scholarship cost of a break, though: waiver rules require continuous study without leaves or breaks and completion in the normal four-year period, with medical gaps allowed on a doctor’s confirmation.

Scholarships and waivers: the rules that turn CGPA into money

NDUB’s financial aid page, verified live for this guide, sets the following conditions. Every one of them is a CGPA or attendance rule in disguise:

• CGPA floor 3.00. The scholarship candidate’s CGPA must be a minimum of 3.00 (B) on a scale of 4. Waivers and scholarships are revoked if a recipient’s grade falls below 3.00.
• Attendance floor 85%. A student with lower than 85% attendance is not eligible for a waiver or scholarship. This is a different, higher line than the 70% needed to sit final exams (see below). You can be perfectly eligible to sit your exams and still lose your waiver on attendance.
• Any retake kills the next waiver. Any student who repeats or retakes a course is not eligible for a tuition fee waiver for the following semester. If you took a retake in the previous semester, you are not eligible for a waiver or scholarship in the current semester. This is the single most expensive rule in this article: the retake that lifts your CGPA by 0.30 in Example 3 costs you a full semester of waiver.
• Failing or slipping disqualifies you too. If you fail any subject or drop below the required CGPA in a semester, you are not considered for a tuition fee waiver for the following semester, and a recipient with a pattern of failing classes is discontinued.
• Incomplete grades mean pay first, refund later. A student with an incomplete or pending grade must still pay for all courses in full. If the required CGPA is obtained after make-up or grade submission, the excess fees are reimbursed or adjusted in the following semester.
• Caps. A student is eligible for a maximum of two scholarship or waiver categories, and a maximum of 80% scholarship or waiver in total. Waivers apply to tuition fees only, not admission, semester, or club fees.
• Admission waivers are separate. First-semester and whole-degree waivers also exist for SSC/HSC results: 50% for GPA 5 in both SSC and HSC (first semester), 20% for Golden GPA 5 in both (whole four-year), 10% for SSC and/or HSC from Christian Missionary schools or colleges, up to 40% for a second sibling and up to 75% for a third sibling, up to 70% for physically challenged students, and up to 50% for offspring or siblings of full-time NDUB employees. Apply before the semester begins; late applications are not considered.

The merit tiers quoted in the GPA vs CGPA section (30/22/15%) are published on NDUB’s program pages and differ by program. Always check your own program’s page: quoting another program’s band is how students overestimate their waiver by a full tier.

Attendance: two different lines, do not confuse them

NDUB has two attendance thresholds and they do different jobs:

• 70% to sit your finals. Per the UGC-reviewed curriculum document, a student needs 70% class attendance to qualify to write the semester final examinations; below 70%, you must obtain permission from the Registrar’s office. The attendance marks ladder in the same document awards 5 marks at 90% and above, 4 at 85% to below 90%, 3 at 80% to below 85%, 2 at 75% to below 80%, 1 at 70% to below 75%, and 0 below 70%.
• 85% to keep a waiver or scholarship. Per the financial aid page, a student with lower than 85% attendance is not eligible for a waiver or scholarship. The gap between 70% and 85% is where students lose money while staying academically eligible: you can sit every exam with 78% attendance and still watch your waiver disappear.

Graduation: the 2.50 floor and the six-year clock

Per NDUB’s LLB curriculum document, the minimum CGPA required for graduation is 2.50, and the maximum academic years for completion is 6. The same document requires a minimum number of earned credits for the degree; for the Microbiology program the published figures are 135 total credits with a minimum of 130 to be completed in eight semesters. Two cautions. First, the 2.50 floor is documented in the LLB curriculum; other programs publish their own handbooks, so confirm your program’s floor with your department office before your final year, especially if you are sitting between 2.00 and 2.50 and assuming you are safe. Second, NDUB publishes no general probation rule on its public site, and no Dean’s List cutoff was found anywhere in the sources opened for this guide. Any page that quotes you an NDUB probation threshold or a Dean’s List CGPA is guessing; this guide will not. What is documented is sharper and more useful: the 70% exam line, the 85% waiver line, the 3.00 scholarship floor, the 2.50 graduation floor, and the six-year completion clock.

Common mistakes NDUB students make

1. Using the wrong scale. The American Notre Dame scale (A 4.00, A- 3.667, B+ 3.333) and generic 4.0 calculators give wrong answers for NDUB. At NDUB, A is 3.75, A- is 3.50, B+ is 3.25, and there is no C- or D+. Always confirm the calculator is on the UGC Bangladesh scale.
2. Mixing up the 5.00 and 4.00 scales. Your SSC and HSC GPA ran on a 5.00 scale (A+ 5.00). Your university CGPA runs on a 4.00 scale (A+ 4.00). A “3.50” means something completely different in each system. Never compare them directly, and never enter SSC grades into a university calculator.
3. Averaging grade points instead of weighting by credits: the credit-weighting trap. Take four grades: A+ (4.00) in a 1-credit viva, C (2.25) in a 3-credit core course, B (3.00) in a 3-credit theory course, and A (3.75) in a 3-credit theory course. The plain average of the four grade points is (4.00 + 2.25 + 3.00 + 3.75) / 4 = 13.00 / 4 = 3.25. The true GPA weights by credits: (1 x 4.00) + (3 x 2.25) + (3 x 3.00) + (3 x 3.75) = 4.00 + 6.75 + 9.00 + 11.25 = 31.00 over 10 credits, which is 31.00 / 10 = 3.10. The plain average overstates your GPA by 0.15, because it lets a 1-credit A+ count as much as a 3-credit C. The same error in reverse makes students panic over a bad grade in a light course that barely moves anything. Weight by credits, every time.
4. Thinking a retake erases everything. A retake improves your CGPA (best grade counts), but it does not erase the original grade for waiver purposes, and any retake in the previous semester disqualifies you from a waiver in the current semester. Retake for the CGPA, but budget for the lost waiver.
5. Thinking D is a fail, or that passing is graduating. D (2.00) passes the course. But a transcript of D grades sits below the 2.50 graduation floor, so you can pass every course and still not graduate. “Passing” and “safe” are different words at NDUB.
6. Assuming a missed final can be made up. It cannot. There is no make-up exam after the semester final at NDUB; a missed final means repeating the whole course with full payment. The supplementary exam is only for F grades with written marks between 15 and 27 out of 70, at most two courses, at Tk. 4,000 each.
7. Treating an I grade as a pause button. An Incomplete converts to an F in the next semester if you do not sit the make-up final. Clear it in the following semester or it becomes a fail that needs a full retake.
8. Entering marks instead of credits in calculators. The calculator divides by credit hours. Typing “100” (your marks) in the credit column produces nonsense. Credits at NDUB are typically 3 for theory courses, 1 to 2 for labs and viva-voce; check your registration, not your memory.

Tips to protect (and raise) your NDUB CGPA

• Guard your 3-credit courses first. One B- in a 3-credit course hurts three times as much as the same grade in a 1-credit viva. Allocate study time by credit weight, not by fear.
• Bank the 60 marks before the final. Attendance, presentation, assignment, quizzes and the mid-term are 60 of your 100 marks. A strong in-course total means the final only has to defend your band, not rescue it.
• Watch the band edges. Since bands do not round up, a 79 is as far from an A+ as a 75 is. Know which band you are sitting in before finals week and push the borderline courses first; one mark at a band edge is worth 0.25 grade points per credit.
• Protect the 85% attendance line, not just the 70% one. If you hold a waiver, 85% is your real floor. Missing classes costs you twice: once in the 10 attendance marks, and once in the waiver itself.
• Plan retakes like a budget. Rank candidate courses by grade-point gain multiplied by credits (the Example 3 method), and remember the waiver cost: a retake this semester means no waiver next semester. Sometimes the rational move is to accept a C and protect the waiver.
• Recover early, not late. CGPA inertia means a strong first year is worth far more than the same effort in the final year. If your CGPA dipped, front-load the recovery while your credit base is still small.
• Keep a running spreadsheet. Track each semester’s quality points and credits yourself. It takes five minutes per result day and removes all surprise at graduation audit time.
• Compare yourself only with NDUB students. The same UGC scale is used by many Bangladeshi universities, so guides for Green University, World University of Bangladesh, BAUET, BAUST and IIUC use the same table, but their retake, waiver and graduation rules are their own. Never copy another university’s rules onto your NDUB transcript.

Frequently asked questions

What is the NDUB grading scale?

NDUB uses the UGC Bangladesh uniform 4.00 scale: A+ 4.00 (80-100%), A 3.75 (75-79%), A- 3.50 (70-74%), B+ 3.25 (65-69%), B 3.00 (60-64%), B- 2.75 (55-59%), C+ 2.50 (50-54%), C 2.25 (45-49%), D 2.00 (40-44%), F 0.00 (below 40%). The scale is published in NDUB’s UGC-reviewed LLB curriculum document and matches the published NDUB grading policy.

Is D a passing grade at NDUB?

Yes. D (40-44%, 2.00 grade points) clears the course. But it contributes only 2.00 points per credit, so a transcript heavy in D grades will sit below the 2.50 graduation floor documented in the LLB curriculum. Passing a course and qualifying for the degree are two different tests.

What CGPA do I need to graduate from NDUB?

NDUB’s LLB curriculum document sets the minimum CGPA for graduation at 2.50, with a maximum of six academic years for completion. Other programs publish their own handbooks, so confirm your program’s floor with your department office; do not assume a lower number you saw on a forum.

What CGPA do I need to keep my scholarship or waiver?

A minimum CGPA of 3.00 (B) on the 4.00 scale, plus at least 85% attendance, continuous study without breaks, and no fail, retake or repeat in the relevant semester. Merit waiver tiers for one following semester vary by program: for example, MBA, EMBA and M.Sc. CSE students get 30% at 4.00, 22% at 3.94-3.99 and 15% at 3.88-3.93, while LLM and ELT students get 30% at 3.80 and above, 22% at 3.75-3.79 and 15% at 3.70-3.74.

Does a retake replace my old grade at NDUB?

For CGPA, yes: the best grade of the course is counted, and an F or I turns to a neutral R on retake. For waivers, no: waiver decisions use the originally obtained grades, and any retake or repeat in the previous semester disqualifies you from a waiver in the current semester. Grade improvement is also capped at B+ (65-69%), and a previously retaken course cannot be improved.

What happens if I miss my final exam?

There is no make-up exam after the semester final at NDUB. You must repeat the whole course in the following semester with full payment. The only published exception is a sick-bed during finals for a student who falls sick during the exams. Supplementary exams are a separate, narrow route: only for F grades with written marks between 15 and 27 out of 70, at most two courses, at Tk. 4,000 each.

Is NDUB the same as the University of Notre Dame in the USA?

No. NDUB is a private Catholic university in Motijheel, Dhaka, founded by the Congregation of Holy Cross in 2013, using the UGC Bangladesh 4.00 scale. The University of Notre Dame in Indiana, USA, uses a different scale (A 4.000, A- 3.667, B+ 3.333, no A+ grade). Notre Dame College Dhaka is a third, separate institution: an HSC college, not a university. Use only NDUB’s own rules and the UGC scale for your NDUB results.

Conclusion

NDUB’s grading system is simple at its core and sharp at its edges. The core is the UGC 4.00 table and the credit-weighted formula, and both are easy to check on the homepage calculator once you select the right scale. The edges are where NDUB students actually lose money and time: a retake that lifts your CGPA but kills your waiver, a missed final that cannot be made up, an Incomplete that quietly becomes an F, a supplementary window that only opens for F grades with written marks between 15 and 27, and two attendance lines (70% for exams, 85% for waivers) that punish different mistakes. Learn those edges now, track your quality points and credits every semester, and confirm the two items NDUB does not publish (a Dean’s List cutoff and a general probation rule) with your department handbook rather than a forum post. Your CGPA is a weighted average, not a mystery: every course, every credit, every band edge is a number you can compute yourself, and this guide has shown you exactly how.
