UIU Grading System 2026: Grades, GPA & CGPA Guide

If you’re studying at United International University, you’ve probably heard the warnings from seniors: “UIU grading is brutal — you need 90 just for an A, and there’s no A+ to save you.” It’s true, and it’s deliberate. This guide explains exactly how UIU’s grading system works in 2026: the official grade table, how your GPA and CGPA are calculated, what happens when you retake a course, and the probation rules almost nobody reads until it’s too late.

The Short Answer

• UIU uses a 4.00 scale with no A+. The highest grade is a plain A, worth 4.00, and it starts at 90 marks.
• A- is 86–89 (3.67), B+ is 82–85 (3.33), B is 78–81 (3.00). Every band is a few marks higher than what most Bangladeshi universities ask for.
• D (55–57, 1.00) is the lowest passing grade. Anything below 55 is an F, earns zero credit, and must be retaken.
• Term GPA = Σ (course credits × grade points) ÷ Σ credits for one trimester. CGPA = the same calculation across every course you’ve completed.
• 2.00 is the magic number. Drop below a 2.00 CGPA and you’re on academic probation; stay there and you can be dismissed.
• UIU runs on trimesters — three terms a year — so probation clocks and retakes move faster than at semester-system universities.

Calculate Your UIU CGPA the Fast Way

The quickest way to know where you stand is to punch your courses into a calculator built for UIU’s exact scale. CGPAPro’s UIU CGPA calculator already uses the official UIU grade points — A- counts as 3.67, B+ as 3.33, and so on — so you don’t have to translate anything yourself:

Screenshot: the CGPAPro UIU calculator with the worked example from this article — five courses, 16 credits, trimester GPA 3.25. Add your own courses the same way.

To use it: pick your grades from the dropdown, type each course’s credit hours, and your GPA appears instantly. The rest of this guide shows you the math behind it, so you can double-check anything by hand.

The Official UIU Grade Table (2026)

This is the table from UIU’s own Grading & Performance Evaluation page. If any third-party calculator shows you something different, this table wins:

Three things jump out. First, there is no A+ — an A at 90 is the ceiling, and it’s worth the same 4.00 that an A+ earns elsewhere. Second, the bands are narrow: most grades cover just 3–4 marks, so a single bad quiz can genuinely move your letter grade. Third, the fail line sits at 55, lower than NSU’s 60 — UIU is harsh at the top but gives you a slightly longer runway at the bottom.

UIU also uses two administrative grades that carry no grade points: I (Incomplete) and W (Withdrawn). An I can be assigned by your course teacher in special circumstances, and you must clear it within 15 days of the following trimester — otherwise it automatically becomes an F.

Warning: Some “UIU CGPA Calculators” Use the Wrong Scale

This is worth saying plainly because it costs students real CGPA points on paper. Several popular student-built UIU calculator tools floating around GitHub use outdated or simply wrong grading tables — one uses A- at 85–89 and B+ at 80–84, another applies a generic UGC-style scale with an A+ that UIU has never used. If you calculate your CGPA with the wrong table, you’ll walk into advising with a number that doesn’t match your transcript.

The rule is simple: the table on uiu.ac.bd is the only one that counts. A at 90, A- at 86–89 worth 3.67, no A+. The CGPAPro UIU calculator linked above follows the official table.

How UIU Calculates Your GPA and CGPA

UIU’s official formula is the standard weighted average, and it applies at two levels:

• Term (trimester) GPA = total grade points earned this trimester ÷ total credits taken this trimester.
• CGPA = total grade points earned in all courses completed so far ÷ total credits completed so far.

In symbols: GPA = Σ (C_i × G_i) ÷ Σ C_i, where C_i is the credit hours of course i and G_i is its grade point.

The steps, in order:

1. For each course, multiply its credit hours by the grade point of the letter grade you earned.
2. Add all those products together — that’s your total grade points.
3. Add up all the credit hours.
4. Divide total grade points by total credits. That’s your GPA.

One detail that matters: a D or higher counts as earned credit hours. An F earns zero grade points and zero earned credits — and you must retake the course.

Worked Example: One Trimester, Five Courses

Let’s walk through a real trimester for a fictional CSE student, Rahim. He takes five courses:

Total grade points = 12.00 + 11.01 + 9.99 + 12.00 + 6.99 = 51.99.
Total credits = 3 + 3 + 3 + 4 + 3 = 16.
Trimester GPA = 51.99 ÷ 16 = 3.25.

Notice how expensive that C+ was: EEE 111 dragged the whole trimester down by nearly a tenth of a point, even though Rahim aced CSE 111. With bands this narrow, one weak course per trimester is the difference between a 3.5 and a 3.2 — which is exactly why UIU seniors obsess over retakes.

Retake at UIU: The Exact Math (and What the Official Page Doesn’t Say)

This is the question every UIU student asks, and the answer has two layers. The official grading page says: “Students may select to retake a course if he or she thinks grade improvement is possible. Students who wish to retake a course must register for the course again and will have to pay tuition and other applicable fees.” That’s it — no formula.

In practice, every student-built UIU calculator implements the same math, and it matches how the registrar’s office treats retakes: the new grade replaces the old one in your CGPA, and the credits are not counted twice. I have to be honest with you, though: this replacement formula is student practice, confirmed by every UIU tool in use — it is not spelled out on the official page. If your situation is unusual (scholarship conditions, graduation audit), confirm with your department office.

Here’s the retake math, step by step, using Rahim again. Suppose before this trimester Rahim had completed 30 credits with 87 total grade points:

CGPA before retake = 87 ÷ 30 = 2.90.

One of those old courses was a 3-credit F (0 points) that he’s now retaking. He scores a B (3.00) this time:

• Remove the old contribution: 87 − (3 × 0.00) = 87
• Add the new contribution: 87 + (3 × 3.00) = 96
• Credits stay at 30 — the course is not double-counted
• New CGPA = 96 ÷ 30 = 3.20

One successful retake lifted him from 2.90 to 3.20. That’s the entire UIU retake game: find your lowest grade-point courses, retake them, and never let the credits double-count in your own spreadsheet. A common mistake is adding the retaken credits to your total (making it 33 credits), which silently deflates your CGPA.

Repeat vs Retake: Two Different Words at UIU

You’ll hear both words on campus, and they don’t mean the same thing — though, again, this distinction is commonly reported rather than published on the official grading page:

• Repeat = you got an F. The course is mandatory to take again, with full tuition payment, because you earned no credit.
• Retake = you passed but want a better grade. It’s optional, you re-register, and you pay tuition and applicable fees again.

Either way, budget for it: retaking means paying for those credits a second time, and student reports indicate tuition waivers and scholarships generally don’t cover retaken courses. Treat the fee as confirmed only by your accounts office — but plan for it.

UIU Runs on Trimesters, Not Semesters

One structural fact that shapes everything else: UIU’s academic year is divided into trimesters — three terms per year — and the official grading page consistently refers to “trimester final examinations.” (A few department course-plan pages describe a 20-week “semester” format, so you’ll see both words around campus, but the grading and probation machinery runs on trimesters.)

Why does this matter? Three reasons:

• Probation is counted in trimesters. “Three consecutive probations” means three terms — roughly one calendar year, not a year and a half.
• You get three shots a year at fixing your CGPA instead of two. A bad Spring can be repaired by Fall without waiting a full year.
• An Incomplete (I) must be cleared within 15 days of the following trimester — the clock is shorter than it looks.

How Your Final Marks Are Actually Built

UIU grades continuously through the trimester — your final mark isn’t decided by one exam. The official breakdown includes quizzes and in-course tests, class participation, attendance, homework and assignments, case studies, mid-trimester exams, and the trimester final. The exact split varies by department:

• Computer Science & Engineering example: attendance 5%, assignment 5%, class tests 20%, mid-term 30%, final 40%.
• English / Pharmacy / EDS example: attendance + assignment 10%, quizzes 10%, mid-term 30%, final 50%.

And there’s a hard floor: minimum 80% attendance is required. With grade bands only 3–4 marks wide, the attendance and quiz components aren’t padding — they’re often the difference between an A- and a B+. Students who treat class tests as throwaway quizzes are donating grade points every single week.

Probation Policy 2025: The Clauses Nobody Reads Until It’s Too Late

In 2025, UIU’s Registrar issued a formal Probation Policy that applies to all existing and new students. Almost no student guide covers it in detail. Here it is, clause by clause:

• The trigger is CGPA 2.00. Fall below 2.00 at any point and you’re placed on Academic Probation. A 2.00 is also the minimum CGPA required to graduate — for both undergrad and graduate programs.
• Three consecutive notices, then dismissal. Undergraduates with fewer than 60 completed credits get a maximum of three consecutive probation notices (one per trimester). If your CGPA isn’t back at or above 2.00 within that window, you’re dismissed.
• The safety valve: if your term GPA is 2.00 or higher during a probation trimester — even if your CGPA hasn’t recovered yet — probation continues as long as your term GPA stays at 2.00+. But the moment your term GPA dips below 2.00 during this extension, you’re dismissed. So: keep every single trimester above 2.00 while you’re climbing out.
• 60+ credits: the same three-notice structure, but departments may grant continued probation in exceptional cases with Academic & Admin Committee approval.
• Graduate students: the same structure at the 15-credit line — strict dismissal below 15 credits, possible committee exception at 15+.
• Minimum 6 credits per trimester while on probation (undergrads). You can’t hide from the problem by taking one easy course.
• No department change while on probation. Thinking of escaping a tough major mid-probation? Not allowed.
• Your parents get notified — a copy of the probation notice plus a transcript marked “PROBATION.” And probation students must attend mandatory counseling and special improvement classes. Skip the improvement programs, and you’re capped at three notices before dismissal.
• The counter resets: once you exit probation, any future probation starts counting from zero again.
• Dismissed students can return — but only through the regular admission test, treated as a new student. Courses where you previously earned a D or above can be waived.

The practical takeaway: probation at UIU is a three-trimester countdown with exactly one escape hatch (term GPA ≥ 2.00 every time). If your CGPA slips under 2.00, your very next trimester is the most important one of your degree — plan it like your enrollment depends on it, because it does.

Is UIU Grading Too Strict? The University Answered — With Data

Here’s something almost no grading guide mentions: UIU students formally proposed making the grading scale easier, and the university actually investigated it. According to an official notice from the UIU authorities, an expert committee reviewed the proposal and the university decided to keep the strict scale. Their reasoning, backed by their own numbers:

• Universities with lower mark thresholds for an A tend to mark more stringently — an easier-looking scale doesn’t mean easier grades.
• Relaxing the scale risked branding UIU graduates as sub-standard with employers.
• The data: about 22% of students earn an A in a given course, over 60% reach a B, and only ~6% land on a D.
• Among roughly 13,000 graduates, about 25% finished with a CGPA above 3.5 and over 60% above 3.0. The scale is strict, but a quarter of graduates still clear 3.5.
• Employment tracked across 7,689 graduates: ~63% formal employment for below-3.0 CGPA holders vs ~75% for higher CGPA holders.

So the official answer to “is UIU too strict?” is: yes, it’s strict on purpose, and the university defends it as a signal of quality to employers. Whether you agree, the practical move is the same — the scale isn’t changing, so learn to play it: protect your A- bands (86–89), retake your lowest courses early, and never let attendance marks slip.

UIU vs NSU, AIUB, BRACU, IUB: The Same 85%, Five Different GPAs

This is where UIU’s strictness becomes concrete. Take a student scoring 85% — a strong result anywhere. Here’s what it earns at five Bangladeshi private universities (from each university’s official table):

The same 85% is worth 3.33 at UIU and 3.75 at AIUB — a 0.42 gap per course, which compounds across a degree. UIU students carry the heaviest “marks tax” in the country alongside NSU. The flip side, straight from UIU’s own data: employers know it. A 3.4 from UIU signals something different than a 3.4 from a university where 85% buys an A — which is precisely the argument the expert committee made for keeping the scale.

For the full three-way breakdown, see our NSU vs IUB vs BRACU comparison, and for the rest of the Bangladesh cluster, the AIUB grading guide and DIU grading guide.

GPA vs CGPA at UIU — Don’t Mix Them Up

Students use the two interchangeably, and it causes real confusion at advising time:

• Trimester GPA covers one trimester only. It’s the number that decides whether your probation continues or ends (the 2.00 safety valve runs on term GPA).
• CGPA covers your entire academic history. It’s the number on your transcript, the one employers ask about, and the one that must be ≥ 2.00 for graduation and good standing.

A single great trimester can save you from dismissal (term GPA ≥ 2.00 keeps probation alive) while barely moving your CGPA. Both numbers matter, for different reasons — track them separately.

6 Mistakes UIU Students Make With Grading

1. Using a generic UGC-scale calculator. The standard Bangladesh UGC scale has an A+ and different bands. UIU doesn’t use it. Always use UIU’s official table — or the UIU-specific calculator.
2. Double-counting retake credits. When you retake a 3-credit course, your credit total stays the same. Adding 3 more credits deflates your CGPA on your own spreadsheet and hides real progress.
3. Treating class tests as throwaway. With 3–4 mark bands, the 20% class-test component (or 10% quizzes) routinely decides your letter grade. An 85 vs an 86 is the difference between B+ and A-.
4. Letting attendance slide. Below 80% attendance is a policy problem, and the 5–10% attendance marks are the cheapest grade points in the whole system.
5. Ignoring the Incomplete deadline. An I becomes an F automatically 15 days into the next trimester. Set a reminder the day you receive it.
6. Discovering probation rules during probation. The three-notice countdown starts whether you’ve read the policy or not. If your CGPA is anywhere near 2.2, read the probation section of this guide twice.

7 Tips: Playing UIU’s Scale to Your Advantage

1. Defend the 86 line. A- (3.67) vs B+ (3.33) is a 0.34 swing per course. When you’re at 84–85 with one assessment left, that’s where your study hours go.
2. Retake early, retake once. Your lowest grade-point courses are the highest-ROI retakes. One F→B conversion moved our example student from 2.90 to 3.20.
3. Front-load attendance and quizzes. These marks are nearly free and they’re banked before finals pressure hits.
4. Count in trimesters. Plan CGPA repair across three terms a year, not two. A bad Spring doesn’t have to define your year.
5. Know your D-line. At 55–57, a D earns credit and keeps you moving. If you’re failing a course beyond rescue, salvaging a D beats an F and a mandatory repeat.
6. Keep term GPA above 2.00 no matter what. Even in a bad trimester, crossing 2.00 for the term keeps the probation safety valve open.
7. Verify with the official table every time. Grading pages get updated; third-party tools don’t. When in doubt, uiu.ac.bd wins.

FAQs: UIU Grading System

Does UIU have A+?

No. UIU’s highest grade is a plain A (90–100), worth 4.00. Several third-party UIU calculators incorrectly include an A+ — ignore them.

How many marks are needed for an A at UIU?

90. The A band is 90–100 (4.00), A- is 86–89 (3.67). These are among the highest A thresholds of any private university in Bangladesh.

What is the minimum CGPA to graduate from UIU?

2.00 — for both undergraduate and graduate programs. The same 2.00 line triggers academic probation if you fall below it.

How does a retake affect my CGPA at UIU?

The official page only says you may re-register for a course and pay the fees again. In practice — as implemented by every UIU student calculator — the new grade replaces the old one and credits are not double-counted. Confirm unusual cases with your department.

What happens if my CGPA drops below 2.0 at UIU?

You’re placed on academic probation. Undergrads with under 60 credits get a maximum of three consecutive probation notices (one per trimester) to climb back to 2.00, with a safety valve: keep your term GPA at 2.00+ and probation continues. Fail that and you’re dismissed — though you can re-enter through the regular admission test.

Is UIU grading harder than NSU or BRACU?

At the top end, yes — UIU needs 90 for an A with no A+ available, while NSU needs 93 for an A and BRACU’s A+ starts at 97. UIU’s own expert committee reviewed a proposal to soften the scale and decided to keep it, arguing the strict scale signals quality to employers.

Does UIU use semesters or trimesters?

Trimesters — three terms per year. The grading and probation rules are written in trimester terms, which means probation clocks and retake opportunities move faster than at semester-system universities.

Final Word

UIU’s grading system is strict by design: 90 for an A, no A+, narrow 3–4 mark bands, and a probation policy with real teeth. But it’s also fully legible — one official table, one formula, and a trimester rhythm that gives you three chances a year to fix things. Learn the table, protect your A- bands, retake your weakest courses early, and keep every trimester above 2.00. Do that, and you’ll be in the quarter of graduates who clear a 3.5 — on a scale employers respect.
