How to Calculate GPA in Nigeria
Most Nigerian Universities and Polytechnics use the NUC 5.0 Grading System. Calculating your GPA involves two main numbers: your Total Grade Points and your Total Units.
The Formula
GPA = Total Grade Points (TGP) ÷ Total Units (TNU)
Note: Grade Points are calculated by multiplying your Score Grade (e.g., A=5) by the Course Unit.
Standard Grading Scale:
- A (70-100%) = 5 pts
- B (60-69%) = 4 pts
- C (50-59%) = 3 pts
- D (45-49%) = 2 pts
- E (40-44%) = 1 pt
- F (0-39%) = 0 pts
Example Calculation:
Imagine a student taking 3 courses in a semester. Here is how their result is calculated:
| Course Code | Score | Grade | Point (A) | Unit (B) | Total Points (A × B) |
|---|---|---|---|---|---|
| MTH 101 | 75 | A | 5 | 3 | 15 |
| ENG 102 | 65 | B | 4 | 2 | 8 |
| PHY 103 | 58 | C | 3 | 3 | 9 |
| TOTALS: | 8 Units | 32 Points | |||
Final Step: Divide Points by Units
GPA = 32 (Points) ÷ 8 (Units) = 4.00
This result means the student is on a Second Class Upper (2:1) standing for this semester.
How to Calculate CGPA in Nigeria
Your Cumulative Grade Point Average (CGPA) is the average of all your semesters combined. It determines your final class of degree (First Class, Second Class, etc.).
The CGPA Formula
CGPA = Total Grade Points (All Semesters) ÷ Total Units (All Semesters)
Tip: You cannot just add your GPAs together and divide by 2. You must weight them by the Units taken.
Example Calculation:
Let’s calculate the CGPA for a student moving into their second year (Year 2, Semester 1):
| Semester | Total Units (A) | Semester GPA (B) | Total Points (A × B) |
|---|---|---|---|
| Year 1 – Sem 1 | 15 | 4.00 | 60.0 |
| Year 1 – Sem 2 | 18 | 3.50 | 63.0 |
| Year 2 – Sem 1 | 17 | 4.20 | 71.4 |
| CUMULATIVE: | 50 Units | — | 194.4 Points |
Step 1: Sum of Total Points = 60 + 63 + 71.4 = 194.4
Step 2: Sum of Total Units = 15 + 18 + 17 = 50
Step 3 (Final Result):
CGPA = 194.4 ÷ 50 = 3.89
(Rounded to 2 decimal places)
🎉 Verdict: With a CGPA of 3.89, this student is firmly in the Second Class Upper (2:1) division.
