Pakistan's Higher Education Commission (HEC) grading system is a uniform semester system built on a 0.00–4.00 grade-point scale. Each course grade maps to a grade point (A = 4.00 down to F = 0.00); your semester GPA (SGPA) is the credit-hour-weighted average of those points, and your CGPA is the same average across every semester. HEC publishes the framework; each university then sets its exact marks-to-grade cut-offs within it.
The HEC 4.0 grade scale
HEC's fractionalized grading table maps each letter grade to a range of grade points and an equivalent percentage under the semester system:
| Grade | Grade points | Percentage (semester system) |
|---|---|---|
| A | 3.67 – 4.00 | 85 and above |
| A- | 3.34 – 3.66 | 80 – 84 |
| B+ | 3.01 – 3.33 | 75 – 79 |
| B | 2.67 – 3.00 | 71 – 74 |
| B- | 2.34 – 2.66 | 68 – 70 |
| C+ | 2.01 – 2.33 | 64 – 67 |
| C | 1.67 – 2.00 | 61 – 63 |
| C- | 1.31 – 1.66 | 58 – 60 |
| D+ | 1.01 – 1.30 | 54 – 57 |
| D | 0.10 – 1.00 | 50 – 53 |
| F | 0.00 | Below 50 |

HEC also assigns each CGPA a percentage using the same band table — a rule that surprises many students because it is not a flat "CGPA × 25". We cover it in full in CGPA to percentage in Pakistan.
Semester system vs the annual system
Pakistan runs two parallel grading traditions, and knowing which one your transcript uses matters:
- Semester system (HEC 4.0). Continuous assessment across a semester — quizzes, assignments, midterms and a final — produces a letter grade per course, an SGPA per semester, and a cumulative CGPA on the 0–4.0 scale. This is the standard HEC set for degree-awarding universities.
- Annual system. The older model, still used by some affiliated colleges and for BA/BSc-pass streams, evaluates you on year-end exams and reports a raw percentage plus a division: First Division at 60% and above, Second Division 45–59%, and Third Division 33–44%.
Division bands per the credential-evaluation reference for Pakistan: Scholaro — Grading System in Pakistan. If your result shows a division rather than a CGPA, you are on the annual system, and the 4.0 table above does not apply directly.
How each university applies the framework
Because HEC only recommends the framework, every university fixes its own exact marks-to-grade cut-offs and grade-point values within it. The scale is uniform; the numbers on the boundaries are not:
- COMSATS (CUI) uses A = 4.00, A− = 3.66, B+ = 3.33.
- FAST-NUCES rounds to 3.67 / 2.67 / 1.67 at the band tops.
- NUST uses a coarser table — B+ = 3.50, and no minus grades at all.
So the same 78% can be a B+ worth 3.33 at one university and a different grade point at another. For a result that matches your transcript, use your own institution's calculator: browse Pakistan university GPA calculators or the full list of supported universities — each has its official scheme built in.

How your SGPA and CGPA are calculated
Every HEC-compliant university uses the same credit-hour-weighted average — credit hours are the weights:
CGPA = Σ(credit hours × grade point) across all semesters ÷ total credit hours
Formula per the HEC Policy Guidelines (§14).
Worked example — three courses in one semester:
- Calculus (3 credit hours, A = 4.00) → 3 × 4.00 = 12.0 quality points
- Programming (3 credit hours, B+ = 3.33) → 3 × 3.33 = 9.99
- Physics (4 credit hours, B = 3.00) → 4 × 3.00 = 12.0
- Total quality points = 33.99; total credit hours = 10 → SGPA = 33.99 ÷ 10 = 3.40
Add the next semester's quality points and credit hours to the running totals and re-divide — that cumulative figure is your CGPA. You can do this automatically in the CGPA Calculator for Pakistan.
Passing, probation, and graduation minimums
HEC sets the only hard floors; everything above them is a university convention:
- Per course: D (grade point 1.00, ≈50%) is the minimum passing grade.
- To graduate: a minimum 2.00 CGPA is required to complete a BS degree, and 2.50 for MS/MPhil.
- Probation: a CGPA below 2.00 places a student on academic probation, usually with a limited window to recover.
Minimums per the HEC Policy Guidelines (§15).
