What is GPA and CGPA?
GPA stands for Grade Point Average, and it measures your academic performance for a single semester. CGPA, or Cumulative Grade Point Average, is the average of all your GPAs across multiple semesters in the university.
Nigeria’s 5.0 GPA Grading Scale
This grading system is commonly used across Nigerian universities like Bayero University, Kano (BUK), University of Ibadan (UI), UNILAG, UNN, FUTA, and many others:
| Score (%) | Grade | Grade Point |
|---|---|---|
| 70–100 | A | 5.00 |
| 60–69 | B | 4.00 |
| 50–59 | C | 3.00 |
| 45–49 | D | 2.00 |
| 40–44 | E | 1.00 |
| 0–39 | F | 0.00 |
Example: First Semester GPA Calculation
Let’s say you’re a first-year student with the following results:
| Course | Credit Unit | Grade | Grade Point | Quality Points (CU × GP) |
|---|---|---|---|---|
| MTH101 | 3 | A | 5 | 15 |
| PHY101 | 3 | B | 4 | 12 |
| GNS101 | 2 | C | 3 | 6 |
| CHM101 | 3 | A | 5 | 15 |
| GST101 | 2 | A | 5 | 10 |
Total Grade Points = 15 + 12 + 6 + 15 + 10 = 58
Total Credit Units = 3 + 3 + 2 + 3 + 2 = 13
GPA = 58 ÷ 13 = 4.46
Example: Second Semester GPA Calculation
| Course | Credit Unit | Grade | Grade Point | Quality Points (CU × GP) |
|---|---|---|---|---|
| MTH102 | 3 | B | 4 | 12 |
| PHY102 | 3 | C | 3 | 9 |
| GNS102 | 2 | D | 2 | 4 |
| CHM102 | 3 | B | 4 | 12 |
| GST102 | 2 | D | 2 | 4 |
Total Grade Points = 12 + 9 + 4 + 12 + 4 = 41
Total Credit Units = 13
GPA = 41 ÷ 13 = 3.15
How to Calculate CGPA in Nigeria
CGPA = Total Grade Points of All Semesters ÷ Total Credit Units of All Semesters
From our examples:
- Total Grade Points = 58 (semester 1) + 41 (semester 2) = 99
- Total Credit Units = 13 + 13 = 26
CGPA = 99 ÷ 26 = 3.81
