Calculate your NUST GPA the way the Examination Branch does — on NUST's official 8-grade relative scale (A = 4.00 down to D = 1.00, no minus grades). This page gives you three tools: a semester GPA calculator, a CGPA tracker, and a standing checker that tells you whether you're clear, on warning, on probation, or meeting your programme's graduation floor. Free, no sign-up, works on any device.
Add every course you took this semester with its credit hours and the letter grade from your result. D+ and D are undergraduate grades (1.50 / 1.00); F earns 0.00 and no credit.
Now add this semester's courses (same letter-grade entry as above):
How to use the NUST GPA calculator
Semester GPA
List every course from the semester, enter its credit hours, and pick the letter grade exactly as it appears on your transcript. The calculator multiplies each course's credit hours by its grade point, adds those quality points up, and divides by total credit hours. The per-course breakdown table shows every multiplication, so you can cross-check against your own result.
CGPA tracker
Enter the credit hours you have already completed and your CGPA before this semester, then add this semester's courses. The tracker converts your old CGPA back into quality points, adds the new semester's, and divides by the new total — the same running-average method the Examination Branch uses.
Standing checker
Enter your CGPA, this semester's GPA, your semester number, and your school group. The checker applies NUST's actual rules: probation only when CGPA falls below 2.00 (never in the first semester), a warning for a semester GPA below 2.00 or any F/XF grade, and the 2.00 vs 2.50 graduation floor by school group.
The official NUST grading scale
NUST's undergraduate grade set has eight letter grades — there are no minus grades (no A−, B−, or C−). The grade points are fixed across all 21 constituent institutions, from SEECS in Islamabad to PNEC in Karachi. Sourced from the NUST Undergraduate Student Handbook (Revised 2025), available on nust.edu.pk.
| Letter grade | Grade points | Meaning |
|---|---|---|
| A | 4.00 | Outstanding |
| B+ | 3.50 | Very good |
| B | 3.00 | Good |
| C+ | 2.50 | Average |
| C | 2.00 | Satisfactory |
| D+ | 1.50 | Pass (undergraduate only) |
| D | 1.00 | Pass (undergraduate only) |
| F | 0.00 | Fail — earns no credit |
Administrative grades also exist: I (Incomplete), W (Withdrawn/Dropped), Q (Qualified), T (Transfer), and XF — an F awarded for shortage of attendance, worth 0.00 grade points. To earn a course's credit hours you must score at least 1.0 grade points (a D).
Why there are no percentage bands (relative grading, explained)
It is NUST policy to work out GPA by awarding relative grading on a scale of 1.00–4.00. In plain terms: your instructor compares your performance with your class cohort (the distribution-gap method) and assigns letter grades from that comparison, rather than from fixed percentage cut-offs. The percentage that earns an A in one section can earn a B+ in another — but the grade points attached to each letter are identical everywhere.
This is exactly why percentage-based "NUST calculators" are fiction: no fixed table of "85–89% = A" exists in the handbook. Enter letter grades, never percentages. If a tool asks for your marks to compute a NUST GPA, it is guessing your grades for you — and guessing wrong.
The formulas
Semester GPA = total quality points ÷ total credit hours, where each course's quality points = credit hours × grade points.
CGPA = (previous quality points + new quality points) ÷ (previous credit hours + new credit hours). Previous quality points = previous credit hours × previous CGPA.
Graduation rule: minimum CGPA 2.00 for most undergraduate programmes; minimum CGPA 2.50 for Business & Management and Social Sciences programmes (with at least C+ in project work for BBA). Probation rule: CGPA below 2.00 puts you on probation — except in the first semester, where it cannot apply. A semester GPA below 2.00, or any F/XF grade, triggers an academic warning instead.
Worked examples (every step shown)
Example 1 — a strong semester: 3.30
| Course | Cr. hrs | Grade | Grade pts | Quality pts |
|---|---|---|---|---|
| CS101 | 3 | A | 4.00 | 12.00 |
| MA101 | 3 | B+ | 3.50 | 10.50 |
| PH101 | 3 | B | 3.00 | 9.00 |
| EE101 | 4 | C+ | 2.50 | 10.00 |
| HU101 | 2 | A | 4.00 | 8.00 |
Total quality points = 12.00 + 10.50 + 9.00 + 10.00 + 8.00 = 49.50. Total credit hours = 15. Semester GPA = 49.50 ÷ 15 = 3.30.
Example 2 — a rough semester with an F: 1.46 and a warning
| Course | Cr. hrs | Grade | Grade pts | Quality pts |
|---|---|---|---|---|
| CS201 | 3 | C | 2.00 | 6.00 |
| MA201 | 3 | D+ | 1.50 | 4.50 |
| EE201 | 4 | F | 0.00 | 0.00 |
| HU201 | 2 | B+ | 3.50 | 7.00 |
Total quality points = 6.00 + 4.50 + 0.00 + 7.00 = 17.50. Total credit hours = 12 (the failed course's hours still count in the denominator). Semester GPA = 17.50 ÷ 12 = 1.46. The F also means zero credit earned for EE201, and the semester GPA below 2.00 triggers an academic warning.
Example 3 — CGPA after a new semester: 3.30
Previously completed: 30 credit hours at CGPA 3.20 → previous quality points = 30 × 3.20 = 96.00. New semester: 16 credit hours at GPA 3.50 → new quality points = 16 × 3.50 = 56.00. New CGPA = (96.00 + 56.00) ÷ (30 + 16) = 152.00 ÷ 46 = 3.30.
Example 4 — the 2.50 graduation floor is unforgiving
A final-year BBA student has completed 124 credit hours at CGPA 2.42 → quality points = 124 × 2.42 = 300.08. The Business school needs 2.50, i.e. 310 quality points over 124 hours — a deficit of 9.92. With 6 credit hours left, even straight A's add only 6 × 4.00 = 24.00: (300.08 + 24.00) ÷ 130 = 324.08 ÷ 130 = 2.49 — still below 2.50. This student cannot graduate on grades alone and needs to discuss options (extra coursework, per school rules) with their academic adviser now, not at the end.

Frequently asked questions
Does NUST use relative or absolute grading?
Relative. University policy is to award grades on a 1.00–4.00 scale by comparing each student's performance with the class cohort (the distribution-gap method). The letter grade floats with the class; the grade points per letter are fixed.
What is the minimum passing grade at NUST?
You need at least 1.0 grade points — a D — to earn a course's credit hours. An F is worth 0.00 and earns no credit, though its hours still count in the GPA denominator.
Does NUST have A−, B− or C− grades?
No. The official undergraduate set is A, B+, B, C+, C, D+, D and F — eight grades, no minus grades. Any table showing minus grades is not NUST's scale.
What CGPA do I need to graduate from NUST?
Minimum CGPA 2.00 for most undergraduate programmes. Students in the Business & Management and Social Sciences schools need a minimum CGPA of 2.50.
When does NUST put a student on probation?
When CGPA falls below 2.00 — and this does not apply in the first semester. A semester GPA below 2.00, or an F/XF grade, triggers an academic warning instead of probation.
Can I convert my percentage marks into a NUST grade?
Not with any official table — NUST does not publish fixed percentage bands because grading is relative to your cohort. Use the letter grades from your transcript in the calculator above.
What is an XF grade?
XF is an F awarded for shortage of attendance. Like a regular F it carries 0.00 grade points, earns no credit, and triggers an academic warning.
Are D+ and D available in graduate programmes?
D+ and D are undergraduate-only grades in the handbook's scale. Graduate programmes operate on their own (higher) thresholds — check your school's graduate handbook.
