What is CGPA?

Grading System at University of Ibadan
Before calculating CGPA, you need to understand UI’s grading system. In UI, grades are assigned based on your performance in a course. Each grade has a corresponding Grade Point (GP), which is used to compute your GPA and CGPA.
Here is the University of Ibadan’s grading system:
| Score (%) | Grade | Grade Point (GP) |
|---|---|---|
| 70 – 100 | A | 5.0 |
| 60 – 69 | B | 4.0 |
| 50 – 59 | C | 3.0 |
| 45 – 49 | D | 2.0 |
| 40 – 44 | E | 1.0 |
| 0 – 39 | F | 0.0 |
Each course you take has a specific number of Credit Units (CU), which also plays a role in CGPA calculation.
Step-by-Step Guide to Calculating GPA
Before calculating CGPA, let’s first understand how to compute GPA (Grade Point Average) for a single semester.
Formula for GPA: GPA=Total Grade PointsTotal Credit UnitsGPA = \frac{Total\ Grade\ Points}{Total\ Credit\ Units}
Example:
Assume you took the following courses in a semester:
| Course Code | Credit Units (CU) | Score (%) | Grade | Grade Point (GP) |
|---|---|---|---|---|
| MAT101 | 3 | 72 | A | 5.0 |
| PHY102 | 2 | 65 | B | 4.0 |
| CHM103 | 3 | 50 | C | 3.0 |
| BIO104 | 2 | 45 | D | 2.0 |
| GST105 | 1 | 80 | A | 5.0 |
Now, we calculate the Total Grade Points: (3×5.0)+(2×4.0)+(3×3.0)+(2×2.0)+(1×5.0)(3 × 5.0) + (2 × 4.0) + (3 × 3.0) + (2 × 2.0) + (1 × 5.0) =15+8+9+4+5=41= 15 + 8 + 9 + 4 + 5 = 41
Total Credit Units: 3+2+3+2+1=113 + 2 + 3 + 2 + 1 = 11
Now, calculate GPA: GPA=4111=3.73GPA = \frac{41}{11} = 3.73
How to Calculate CGPA in University of Ibadan
CGPA is the cumulative measure of all your GPAs from your first semester till your final semester.
Formula for CGPA: CGPA=Total Grade Points of All SemestersTotal Credit Units of All SemestersCGPA = \frac{Total\ Grade\ Points\ of\ All\ Semesters}{Total\ Credit\ Units\ of\ All\ Semesters}
Example:
Assume you have completed three semesters with the following GPAs and credit units:
| Semester | GPA | Total Credit Units (CU) |
|---|---|---|
| 1st | 3.50 | 15 |
| 2nd | 3.75 | 17 |
| 3rd | 3.80 | 16 |
To find the Total Grade Points: (3.50×15)+(3.75×17)+(3.80×16)(3.50 × 15) + (3.75 × 17) + (3.80 × 16) =52.5+63.75+60.8= 52.5 + 63.75 + 60.8 =177.05= 177.05
Total Credit Units: 15+17+16=4815 + 17 + 16 = 48
Now, calculate CGPA: CGPA=177.0548=3.69CGPA = \frac{177.05}{48} = 3.69
This means your CGPA is 3.69, which is close to a Second Class Upper (2:1) classification.
