Frequently Asked Questions
What scale do Nigerian universities use?
Most Nigerian federal universities (UI, UNILAG, OAU, UNIBEN, ABU, UNN) use the 5-point scale. A few, especially private universities like Covenant University and American-model institutions, use the 4-point scale. Check your student handbook to confirm which scale your university uses.
What CGPA do I need for a First Class in Nigeria?
On the 5.0 scale: First Class requires CGPA of 4.50 and above. On the 4.0 scale: First Class requires CGPA of 3.50 and above. These thresholds may vary slightly between universities, so confirm with your institution.
How is CGPA calculated in Nigerian universities?
CGPA = Total Quality Points ÷ Total Credit Units. Quality Points for a course = Grade Point × Credit Units. Then sum all quality points across all semesters and divide by total credit units taken.
Can a bad semester ruin my CGPA?
Yes, but it can be recovered. Since CGPA is cumulative, one poor semester has less impact as you progress. Aim to progressively improve your grades. Some universities allow retaking courses to replace poor grades, though policies vary.
What degree class corresponds to a 3.2 CGPA on 5.0?
On the 5.0 scale: 3.2 falls in Second Class Lower (2:2), which requires 2.50–3.49. While respectable, most employers and postgraduate programs prefer Second Class Upper (3.50+) or First Class.
