How WASSCE Aggregates Work
Your aggregate score is the single most important number in your university application. Here is exactly how it is calculated.
The Formula
Your aggregate is the sum of your best 3 core subject grades plus your best 3 elective grades — 6 subjects total.
Aggregate = (best 3 core grades) + (best 3 elective grades)
Each grade is assigned a numerical value. Lower numbers are better:
| Grade | Points | Label |
|---|---|---|
| A1 | 1 | Excellent |
| B2 | 2 | Very Good |
| B3 | 3 | Good |
| C4 | 4 | Credit |
| C5 | 5 | Credit |
| C6 | 6 | Credit |
| D7 | 7 | Pass |
| E8 | 8 | Pass |
| F9 | 9 | Fail |
Example Calculation
Suppose you scored:
- English Language: B2 (2)
- Core Mathematics: B3 (3)
- Integrated Science: C5 (5)
- Social Studies: A1 (1)
Best 3 core subjects: A1 + B2 + B3 = 1 + 2 + 3 = 6
Suppose your best 3 elective grades are B2 (2), B3 (3), C4 (4):
Elective contribution = 2 + 3 + 4 = 9
Total aggregate = 6 + 9 = 15
An aggregate of 15 is considered very competitive and qualifies you for most programmes.
What is a Good Aggregate?
| Aggregate range | Classification | Typical access |
|---|---|---|
| 6 – 12 | Excellent | Medicine, Law, Pharmacy at UG/KNUST |
| 13 – 18 | Very Good | Engineering, Nursing, Accounting |
| 19 – 24 | Good | Education, Business, Arts at most universities |
| 25 – 36 | Average | Limited options — some distance programmes |
Elective Requirements
An aggregate alone is not enough. Many programmes also require specific elective subjects. For example:
- Medicine requires Biology, Chemistry, and Physics
- BSc Computer Science requires Elective Mathematics
- BSc Pharmacy requires Biology, Chemistry, and Elective Mathematics
If you do not have the required elective, you will not be admitted regardless of your aggregate. AdmitGH automatically checks both your aggregate and your electives when showing you matches.
