If you’re a student preparing for the 2025 West African Senior School Certificate Examination (WASSCE), or a parent eager to support your child’s academic journey, there’s one thing you can’t afford to overlook — the WAEC grading system.
Your WAEC results don’t just reflect months of hard work; they can shape your future, influencing university admissions, scholarship opportunities, and even career prospects.
But here’s the truth: many students focus only on studying hard, ignoring how their performance will be graded. Understanding how WAEC scores are interpreted can make a huge difference in how you approach your exams.
This guide breaks down the 2025 WAEC grading system, compares it to previous versions, and offers smart strategies to help you aim for the best possible grades. Whether you’re chasing that coveted A1 or trying to stay far away from an F9, this article is your roadmap to success.
WAEC Grading Scales: From SSSCE to WASSCE
Before 2006, WAEC used the Senior Secondary School Certificate Examination (SSSCE) grading system, which worked on a simple A–F scale.
But in 2006, WAEC introduced the A1–F9 scale for WASSCE, offering more precise grading and making it easier for universities and employers to assess student performance.
SSSCE Grading Scale: A – F
WASSCE Grading Scale: A1 – F9
Both systems share the same principle:
- A1 or A = Excellent
- F9 or F = Fail
Today, the WASSCE A1–F9 system is the standard grading scale for Nigerian students sitting for WAEC.
2025 WAEC Grading System Explained
Here’s a clear breakdown of the WAEC grading system for 2025 and the percentage range required for each grade:
- A1 (Excellent): 75% – 100%
- B2 (Very Good): 70% – 74%
- B3 (Good): 65% – 69%
- C4 (Credit): 60% – 64%
- C5 (Credit): 55% – 59%
- C6 (Credit): 50% – 54%
- D7 (Pass): 45% – 49%
- E8 (Pass): 40% – 44%
- F9 (Fail): 0% – 39%
Key takeaway: To be considered for most universities and polytechnics, you need a minimum of C6 in your core subjects (English Language and Mathematics).
