A CGPA of 3.90 on the 4.0 scale is a First Class. This is the highest class of degree.
Where 3.90 sits on the 4.0 scale
| Class | CGPA |
|---|---|
| First Class | 3.50 to 4.00 |
| Second Class Upper (2:1) | 3.00 to 3.49 |
| Second Class Lower (2:2) | 2.00 to 2.99 |
| Third Class | 1.00 to 1.99 |
| Below pass mark | 0.00 to 0.99 |
Your CGPA would fall to Second Class Upper (2:1) if it dropped below 3.50.
What grades give a 3.90 CGPA
A CGPA of 3.90 sits between grade B (3 points) and grade A (4 points). For example, about 90% of your credit units at A and 10% at B gives this figure.
| Grade | Score | Points |
|---|---|---|
| A | 70 to 100 | 4 |
| B | 60 to 69 | 3 |
| C | 50 to 59 | 2 |
| D | 40 to 49 | 1 |
| F | 0 to 39 | 0 |
Why the same number means a different class on the 5.0 scale
The two scales do not convert one to one. On the 5.0 scale an A is worth 5 points, and the class limits are different:
| Class | CGPA on the 5.0 scale |
|---|---|
| First Class | 4.50 to 5.00 |
| Second Class Upper (2:1) | 3.50 to 4.49 |
| Second Class Lower (2:2) | 2.40 to 3.49 |
| Third Class | 1.50 to 2.39 |
| Pass | 1.00 to 1.49 |
| Below pass mark | 0.00 to 0.99 |
If a form or school asks for your CGPA on a scale you did not study on, give the class of degree as well as the number, and ask the school how they convert it.
What this class means for applications
Many graduate trainee programmes, banks and scholarships ask for at least a Second Class Upper, so this class meets that common requirement. Postgraduate programmes in Nigeria usually accept it too. Always read the exact requirement in each advert.
Requirements differ by employer and school, so check the advert before you apply.
