How to Calculate CGPA in Nigerian Universities (Simple Guide with Examples)
Many students hear about CGPA from their first day in school, but not everyone truly understands how it works. Some only realize its importance when results come out, and by then mistakes may have already affected their performance.
This guide explains everything in a simple and clear way, based on the Nigerian university system. No complicated words. Just straight explanation you can understand and use.
What is CGPA?
CGPA means Cumulative Grade Point Average.
It is the overall average of all your academic performance from your first semester up to your current level. It shows how well you are doing in school and determines your final class of degree.
Difference Between GPA and CGPA
- GPA – your result for one semester
- CGPA – your total result from beginning till now
So CGPA is the full picture of your academic journey.
Nigerian Grading System (5.0 Scale)
| Grade | Score (%) | Grade Point |
|---|---|---|
| A | 70 – 100 | 5.0 |
| B | 60 – 69 | 4.0 |
| C | 50 – 59 | 3.0 |
| D | 45 – 49 | 2.0 |
| E | 40 – 44 | 1.0 |
| F | 0 – 39 | 0.0 |
What Are Course Units?
Each course has a unit (credit load). Some courses carry more units than others.
- GST courses → 2 units
- Core courses → 3–4 units
- Technical courses → up to 5 units
The higher the unit, the more it affects your CGPA.
CGPA Formula
CGPA = Total Quality Points ÷ Total Course Units
What is Quality Point?
Quality Point = Grade Point × Course Unit
Example: A in a 3-unit course → 5 × 3 = 15
---Example 1: Simple Semester Calculation
| Course | Unit | Grade | Grade Point |
|---|---|---|---|
| GST 101 | 2 | A | 5 |
| MTH 101 | 3 | B | 4 |
| PHY 101 | 3 | C | 3 |
| CHM 101 | 3 | B | 4 |
| CSC 101 | 4 | A | 5 |
Step 1: Quality Points
| Course | Unit | Grade Point | Quality Point |
|---|---|---|---|
| GST 101 | 2 | 5 | 10 |
| MTH 101 | 3 | 4 | 12 |
| PHY 101 | 3 | 3 | 9 |
| CHM 101 | 3 | 4 | 12 |
| CSC 101 | 4 | 5 | 20 |
Total Quality Points = 63
Total Units = 15
GPA = 63 ÷ 15 = 4.20
---Example 2: Impact of a High-Unit Course
| Course | Unit | Grade | Grade Point |
|---|---|---|---|
| Course A | 2 | A | 5 |
| Course B | 2 | A | 5 |
| Course C | 3 | B | 4 |
| Course D | 5 | F | 0 |
Total Quality Points = 32
Total Units = 12
GPA = 32 ÷ 12 = 2.67
This shows how one failed 5-unit course can damage your result.
---Example 3: CGPA for Two Semesters
First Semester: GPA = 3.50, Units = 18 → Quality Points = 63
Second Semester: GPA = 3.00, Units = 20 → Quality Points = 60
Total Quality Points = 123
Total Units = 38
CGPA = 123 ÷ 38 = 3.24
---Example 4: Improving Your CGPA
First Semester: GPA = 2.50 (20 units) → 50 points
Second Semester: GPA = 3.50 (20 units) → 70 points
Total = 120 points ÷ 40 units
CGPA = 3.00
This shows improvement is possible.
