Understanding how your WASSCE grades are being converted into aggregates is important, especially for SHS graduates aiming for university or college admission in Ghana.
If you’re an SHS graduate or currently awaiting your WASSCE results and you are looking to know how to calculate your WASSCE aggregate score, then grab a pen and paper because this article will show you exactly how to do that.
We will help you understand the grading system, how to calculate your aggregate, and what it means for university admission in Ghana.
Before we dive into how to calculate your WASSCE aggregates, we’d like to first explain to you how the WASSCE grading system works and then take you through the process of calculating the aggregates.
WASSCE Grading System
Before you can calculate your aggregate, it’s important to understand how WAEC assigns grades and the points they carry:
| Grade | Score (%) | Interpretation | Aggregate Points |
|---|---|---|---|
| A1 | 75 – 100 | Excellent | 1 |
| B2 | 70 – 74 | Very Good | 2 |
| B3 | 65 – 69 | Good | 3 |
| C4 | 60 – 64 | Credit | 4 |
| C5 | 55 – 59 | Credit | 5 |
| C6 | 50 – 54 | Credit | 6 |
| D7 | 45 – 49 | Pass | 7 |
| E8 | 40 – 44 | Pass | 8 |
| F9 | 0 – 39 | Fail | 9 |
Subjects Used For Your Aggregate
WAEC used six subjects to grade students, so for that matter, if you want to calculate your WASSCE aggregate, you also have to select 6 subjects out of the 9 subjects.
-
3 Core Subjects:
-
English Language
-
Core Mathematics
-
Integrated Science or Social Studies
-
-
3 Elective Subjects (based on your course of study)
For a science applicant, integrated science is often prioritized over social studies.
How to Calculate Your WASSCE Results/Aggregate
Assuming you obtained the following grades in your WASSCE examination:
| Subject | Grade |
|---|---|
| English Language | B3 |
| Core Mathematics | B2 |
| Integrated Science | A1 |
| Social Studies | A1 |
| Physics | A1 |
| Chemistry | B3 |
| Elective Mathematics | B2 |
| Biology | C4 |
Then, to calculate your aggregates, you will have to do the following.
| Subject | Grade | Aggregate Point |
|---|---|---|
| English Language | B3 | 3 |
| Core Mathematics | B2 | 2 |
| Integrated Science | A1 | 1 |
| Physics | A1 | 1 |
| Chemistry | B3 | 3 |
| Elective Mathematics | B2 | 2 |
Total Aggregate Score = 3 + 2 + 1 + 1 + 3 + 2 = 12
In this case, your WASSCE aggregate score is 12, which is considered excellent for university admission.
What Is a Good WASSCE Aggregate?
| Aggregate Score | Admission Chance |
|---|---|
| 6 – 12 | Very High (Top-tier courses) |
| 13 – 18 | Moderate (May be competitive) |
| 19 – 24 | Low (Consider backup options) |
| 25+ | Very Low (May not qualify) |
