Question: how to convert cgpa to percentage in nigeria?
Answer: Your total Course Unit for 100 first semester and the second semester 11 + 9 = 20.
Your total Quality Unit for 100 first semester and the second semester 35 + 43 = 78.
Divide your Cumulative Quality point by Cumulative Course Unit.
That is, 78 / 20 = 3.9 (100 level CGPA)
