WAEC Grading System Explained (2026): Meaning of A1, B2, B3, C4, C5, C6, D7, E8, and F9

If you've recently written the West African Senior School Certificate Examination (WASSCE) or you're preparing for it, you've probably wondered what grades like A1, B2, C6, or F9 actually mean.

Many students celebrate an A1 without knowing the score it represents, while others are unsure whether a C6 or D7 is good enough for university admission.

In this guide, we'll explain the WAEC grading system in simple terms, including the score range for each grade, what each grade means, and the grades required for admission into higher institutions.

What Is the WAEC Grading System?

The West African Examinations Council (WAEC) uses a grading system to assess candidates' performance in each subject. Instead of displaying your exact score on your result slip, WAEC awards a grade that reflects how well you performed in the examination.

The highest grade is A1 (Excellent), while the lowest is F9 (Fail).

WAEC Grading System and Score Range

The table below shows the commonly accepted WAEC grading scale.

Note: WAEC does not officially publish fixed percentage boundaries every year. The score ranges below are widely used for educational guidance and may vary slightly depending on moderation.

A1 (75–100%) – Excellent

An A1 is the highest grade a student can earn in WAEC. It shows that you demonstrated an excellent understanding of the subject and performed exceptionally well.

Students with several A1 grades often have a competitive advantage when applying for highly sought-after courses such as Medicine, Law, Pharmacy, Engineering, and scholarships.

B2 (70–74%) – Very Good

A B2 indicates a very strong performance. Although it's slightly below A1, it still reflects a high level of understanding and is considered an excellent grade for university admission.

B3 (65–69%) – Good

A B3 means you performed well in the subject. It is a solid result that satisfies admission requirements for most institutions where the subject is required.

C4 (60–64%) – Credit

A C4 is a good credit pass. It shows that you have a satisfactory understanding of the subject and comfortably meet the credit requirement for many tertiary institutions.

C5 (55–59%) – Credit

A C5 is also a credit pass. While it may not be among the highest grades, it is accepted by many universities, polytechnics, and colleges.

C6 (50–54%) – Credit

A C6 is the minimum credit grade accepted by most Nigerian universities and many higher institutions.

If your chosen course requires a credit pass in a subject, a C6 is generally acceptable. However, highly competitive courses may require stronger grades because admission is based on merit and competition.

D7 (45–49%) – Pass

A D7 means you passed the subject, but it is not a credit pass.

Most universities do not accept D7 in compulsory admission subjects such as English Language or Mathematics.

E8 (40–44%) – Pass

An E8 is a weak pass. While it shows that you did not fail completely, it usually does not meet the admission requirements for higher institutions.

F9 (0–39%) – Fail

An F9 means you failed the subject.

If you receive F9 in a compulsory subject, you may need to rewrite the examination before you can qualify for admission into many tertiary institutions.

Which WAEC Grades Are Considered Credit Passes?

For university admission, only the following grades are regarded as credit passes:

• A1 (75–100%)
• B2 (70–74%)
• B3 (65–69%)
• C4 (60–64%)
• C5 (55–59%)
• C6 (50–54%)

Grades D7, E8, and F9 are not counted as credit passes.

How Many Credits Do You Need for University Admission?

Most Nigerian universities require candidates to have:

• At least five credit passes.
• Credits in English Language and Mathematics (for most courses).
• Other relevant subjects related to the course of study.

Some institutions and programmes may have additional requirements, so it's always advisable to check the admission guidelines of your preferred school.

Can You Gain Admission with C6 Grades?

Yes.

Many students have successfully gained admission with five C6 grades.

However, admission also depends on:

• Your UTME score.
• Post-UTME performance (where applicable).
• The course you are applying for.
• Competition among applicants.
• The institution's admission policy.

For competitive courses such as Medicine, Law, Nursing, and Engineering, stronger grades can improve your chances.

Final Thoughts

The key is to know where you stand, keep improving, and choose the academic path that best suits your goals.
