If you believe a subject wasn't marked correctly, you can ask WAEC to have it remarked. Here's how the process works.
Start with your school, not WAEC directly
WAEC does not accept remarking requests directly from candidates. School candidates apply through their school; the school forwards the request through the district examinations officer to WAEC. Private candidates should ask at their nearest WAEC office about the private-candidate process.
Decide which subject(s) to request
You can request a remark for specific subjects rather than your whole result — most people apply for the subject(s) where the result seemed unexpected.
Pay the remarking fee
There is a fee per subject, and it does apply even if the remark doesn't change your grade. The exact current amount varies by source and can change — confirm it directly at your school or WAEC office rather than relying on a fixed number here.
WAEC retrieves your script and re-marks it
Once your request reaches WAEC, they retrieve your script and have it reviewed by a chief examiner, independently of the original marking.
Wait for the outcome
This review is usually completed within a few weeks, though it can vary. Your grade may improve, stay the same, or in rare cases go down — WAEC does not guarantee a specific outcome.
There is usually a window after results are released within which remarking requests are accepted — don't wait too long if you're considering this.
This is general guidance, not an official WAEC document. For anything specific to your situation, your school or nearest WAEC office is the most reliable source.
