Frequently Asked Questions
What is WAEC aggregate and how is it calculated?
WAEC aggregate is the sum of your five best grades from your O'Level subjects. Each grade is converted to a point (A1=1, B2=2, etc.), and the five lowest point values are added. A First Class aggregate is 5-9 points, Credit is 10-15, Pass is 16-20, and anything above 20 is considered a Fail.
How do universities use JAMB and O'Level scores?
Most Nigerian universities require both a good JAMB score and a strong O'Level aggregate. The JAMB score is typically weighted 40%, while O'Level is 60% in the final admission score. Different programs at different universities have different cut-off marks, which this calculator helps you check.
What's the difference between WAEC and NECO?
Both WAEC and NECO are Nigerian examination bodies that conduct O'Level exams. They use the same grading system (A1-F9) and point conversions. Most universities accept both equally. The main difference is in which exams you take, but universities typically accept either or both.
Can I use this calculator for Ghana's WASSCE?
Yes! Ghana's WASSCE uses the same grade system as Nigerian WAEC (A1-F9), but with different aggregate calculations (best 6 subjects instead of best 5) and university-specific cut-offs. We've included a dedicated Ghana tab for this purpose.
