What Is WAEC Aggregate?

WAEC aggregate is calculated from your five best subject grades. Each grade earns points — A1=1, B2=2, B3=3, C4=4, C5=5, C6=6, D7=7, E8=8, F9=9 — and the five lowest (best) point totals are added. A perfect aggregate of 5 means five A1 grades. A score of 9 or below is First Class; 10–15 is Credit; 16–20 is Pass. Lower is better.

Two Input Modes

Enter Scores — type your raw score (0–100) and the grade is calculated automatically. Useful when you remember your percentage score.
Enter Grades — select your grade (A1 through F9) directly from a dropdown. Useful when you have your result slip in hand.

WES GPA Conversion

The GPA conversion uses the World Education Services (WES) scale — the standard used when Nigerian O'Level results are evaluated for Canadian and US university applications or immigration purposes. A1=4.0, B2=3.7, B3=3.3, C4=3.0, C5=2.7, C6=2.3, D7=2.0, E8=1.3, F9=0.0. The calculator shows the average GPA across your best five subjects.

Course Eligibility Checker

Select any course from the dropdown to see whether your current O'Level results meet the subject requirements. The checker matches your entered subjects against the compulsory subjects for each course — for example, Medicine requires Biology, Chemistry, Physics, Mathematics and English all at Credit level (C6 minimum). The result shows each required subject and whether your grade qualifies.

WAEC vs NECO vs GCE

All three use the identical A1–F9 grading scale and the same credit/pass/fail definitions. Nigerian universities accept results from all three boards equally. The board toggle at the top does not change the calculation — it is for labelling purposes when you want to note which exam your results are from.

Frequently Asked Questions

WAEC aggregate is the sum of grade points for your five best subjects. Each grade carries a point value: A1=1, B2=2, B3=3, C4=4, C5=5, C6=6, D7=7, E8=8, F9=9. The five subjects with the lowest point totals (your best grades) are selected and added together. The minimum possible aggregate is 5 (five A1 grades). An aggregate of 5-9 is considered First Class, 10-15 is Second Class/Credit, and 16-20 is Pass.
Most Nigerian universities require a minimum of five credits (grades A1 to C6) at one sitting or two sittings, including English Language and Mathematics for most courses. Some courses have additional requirements — Medicine requires credits in Biology, Chemistry, Physics, Mathematics and English. Law at many institutions requires English at C4 or above. Always check the specific requirements for your target university and course.
Using the WES (World Education Services) scale used for international applications: A1 = 4.0, B2 = 3.7, B3 = 3.3, C4 = 3.0, C5 = 2.7, C6 = 2.3, D7 = 2.0, E8 = 1.3, F9 = 0.0. This scale is used when Nigerian O'Level results are evaluated for Canadian or US university admission and immigration purposes.
Yes. NECO (National Examinations Council) results are accepted by all Nigerian universities equally with WAEC results. Both use the identical A1–F9 grading scale with the same credit/pass/fail boundaries. A C6 from NECO and a C6 from WAEC are treated identically by admissions offices. JAMB also accepts both. Some students sit both WAEC and NECO to improve their subject combination.
Yes. Most Nigerian universities accept O'Level results from a maximum of two sittings. You can combine subjects from your first sitting with additional subjects or improved grades from a second sitting. However, you cannot use the same subject from two different sittings — if you have Biology in both, only the better grade is used. Some highly competitive courses and universities require all credits at one sitting — verify with your target institution.
For Medicine and Surgery at Nigerian universities, you need credits in: English Language, Mathematics, Biology, Chemistry and Physics — all at C6 minimum, and most universities require C5 or better. Dentistry has the same requirements. Pharmacy requires Biology, Chemistry and Mathematics. Engineering requires Mathematics, Physics and Chemistry. Computer Science requires Mathematics and Physics at most universities.
