How do I calculate CGPA at a Nigerian university?

CGPA is the sum of (grade points earned Ã— course credit units) for every course you have taken, divided by the total credit units. On the standard Nigerian 5.0 scale, A=5, B=4, C=3, D=2, E=1, F=0. UI uses a 7.0 scale and polytechnics/COEs use a 4.0 scale. This calculator handles all three.

What is the difference between GPA and CGPA?

GPA (Grade Point Average) is your average for a single semester. CGPA (Cumulative GPA) is the running average across every semester you have taken, weighted by credit units. Both use the same grade-point conversion at your institution.

What CGPA scale does my polytechnic use?

Nigerian polytechnics use the NBTE-prescribed 4.0 grading scale with intermediate grades (AB, BC, CD). This calculator includes the full NBTE conversion table. Select your polytechnic for the calibrated calculator.

How do I improve my CGPA from a Third Class to a Second Class?

You need to maintain higher grade points in your remaining semesters. CampusTutor's GPA Forecast projects your final CGPA from your current mastery, identifies the courses where extra effort will lift your classification fastest, and tells you the minimum grades required in your remaining courses.

How Nigerian CGPA Calculation Works

CGPA (Cumulative Grade Point Average) is the weighted mean of every course grade you have earned in your programme. The weighting comes from the credit units assigned to each course — a 6-unit MTH 101 affects your CGPA twice as much as a 3-unit GST 101.

On the standard Nigerian 5.0 scale, the conversion is: A = 5, B = 4, C = 3, D = 2, E = 1 and F = 0. A first class typically requires a CGPA of 4.50 or above; a Second Class Upper sits between 3.50 and 4.49; a Second Class Lower between 2.40 and 3.49; a Third Class between 1.50 and 2.39; and below 1.50 is a Pass.

The University of Ibadan uses a distinctive 7-point scale. Nigerian polytechnics use the NBTE-prescribed 4.0 scale with intermediate grades (AB, BC, CD) — and Colleges of Education use the NCCE-mandated 4.0 scale. This calculator handles all three; select your institution for the calibrated version.
