Question 1

How do I calculate my CGPA in Nigeria?

Accepted Answer

Multiply each course’s units by the points for your grade (on the 5.0 scale A is 5, B 4, C 3, D 2, E 1, F 0), add those up for every semester so far, then divide by the total units you have taken. A semester on its own gives your GPA; all semesters together give your CGPA.

Question 2

What is the difference between GPA and CGPA?

Accepted Answer

GPA is for one semester. CGPA (cumulative grade point average) covers every semester since you started, weighted by units, so a 3-unit course counts three times as much as a 1-unit course.

Question 3

What CGPA is a First Class?

Accepted Answer

On the 5.0 scale most Nigerian universities use, a First Class is 4.50 to 5.00, Second Class Upper 3.50 to 4.49, Second Class Lower 2.40 to 3.49, Third Class 1.50 to 2.39 and Pass 1.00 to 1.49. On the 4.0 scale a First Class starts at 3.50. Check your school’s handbook: a few use slightly different lines.

Question 4

Which scale does my school use, 5.0 or 4.0?

Accepted Answer

Most Nigerian universities and colleges of education use the 5.0 scale. Polytechnics (ND and HND) and some universities use the 4.0 scale, where there is no E and a polytechnic diploma is graded Distinction, Upper Credit, Lower Credit or Pass.

Question 5

How do carry-over courses affect my CGPA?

Accepted Answer

A failed course adds its units with zero points, which pulls your CGPA down. When you retake it, most schools count the new grade as well, so the units are counted twice. Add both attempts in the calculator to see where you stand.

Question 6

Can I still make a First Class?

Accepted Answer

Use “What do I need?” under your result: enter your target CGPA and next semester’s units, and it tells you the GPA you need and a mix of grades that gets you there, or the best CGPA you can still reach.

Question 7

Do I need an account to use the calculator?

Accepted Answer

No. It works without signing up and keeps your courses on this device. If you start free on MyUnit, your semesters come with you and your CGPA updates itself every semester.
