🎓 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
