The West African Examinations Council (WAEC) grading system is essential for every student, parent, or teacher in Nigeria and other West African countries. It determines how students' performances in the West African Senior School Certificate Examination (WASSCE) are evaluated and recorded. Whether you're awaiting your result or preparing for an upcoming exam, knowing what the grades mean helps you understand where you stand academically.
In this comprehensive guide, we'll break down the WAEC grading system, what each grade means, the percentage ranges, and its significance for university admission and job applications.
Understanding WAEC and Its Purpose
WAEC is the examining body that administers the WASSCE across five West African countries: Nigeria, Ghana, Sierra Leone, The Gambia, and Liberia. The exam is usually taken by students in their final year of secondary school. Results from this exam determine eligibility for higher education and are often used for employment screening.
WAEC Grading System (2025)
WAEC uses a letter and number grading system to reflect students' performance. The letter grades run from A1 to F9, while the number scale shows the quality of performance with lower numbers indicating better performance.
Here's a detailed breakdown of the WAEC grading system:
| Grade | Meaning | Score Range (%) | Remarks |
|---|---|---|---|
| A1 | Excellent | 75 – 100% | Distinction |
| B2 | Very Good | 70 – 74% | Upper Credit |
| B3 | Good | 65 – 69% | Lower Credit |
| C4 | Credit | 60 – 64% | Credit Level |
| C5 | Credit | 55 – 59% | Credit Level |
| C6 | Credit | 50 – 54% | Credit Level |
| D7 | Pass | 45 – 49% | Weak Pass |
| E8 | Pass | 40 – 44% | Weak Pass |
| F9 | Fail | 0 – 39% | Fail |
What Do These Grades Mean Academically?
-
A1 to C6: These are considered pass grades and are acceptable for admission into universities, polytechnics, and colleges of education in Nigeria.
-
D7 and E8: These are low passes and may be accepted for certain non-academic purposes but not for university admission.
-
F9: This grade indicates failure and is not accepted for academic advancement.
Implications of WAEC Grades for Tertiary Education
1. University Admission Requirements
To gain admission into Nigerian universities, students are generally required to have at least five credits (A1 to C6), including English Language and Mathematics. If a student gets a D7, E8, or F9 in either English or Maths, they may be denied admission, even with high UTME scores.
2. Polytechnic and College of Education Requirements
These institutions also require five credits, but they may be more flexible depending on the course and institution. However, English and Mathematics are still essential.
3. Rewriting WAEC or NECO
If a candidate scores D7, E8, or F9 in key subjects like English or Mathematics, they are usually advised to sit for a supplementary exam such as WAEC GCE or NECO.
WAEC Grading System vs Other Examination Bodies
WAEC uses its own grading system which is slightly different from other examination bodies like:
-
NECO (National Examinations Council): Similar grading scale.
-
NABTEB (National Business and Technical Examinations Board): More technical in focus.
-
IGCSE or Cambridge O-Level: Uses grades like A*, A, B, etc.
Each system has its own format, but WAEC remains one of the most widely recognized.
How Universities Calculate Aggregate Scores
Most Nigerian universities combine UTME scores, O’Level grades, and post-UTME performance to calculate aggregate scores. WAEC grades (A1 to C6) often have weightings:
-
A1 = 6 points
-
B2 = 5 points
-
B3 = 4 points
-
C4 = 3 points
-
C5 = 2 points
-
C6 = 1 point
The higher your WAEC grade, the more likely you'll score high in aggregate calculations for competitive courses like Medicine, Law, and Engineering.
Tips to Improve WAEC Performance

Start Early: Don’t wait until the exam is close.
-
Use Past Questions: They help you familiarize with the format.
-
Attend WAEC-focused classes or online tutorials
-
Practice Time Management
-
Revise Smartly: Focus on English Language, Mathematics, and your core subjects.
