WAEC is going fully CBT.
This is the exact system your school can use to prepare students for computer-based exams — from JSS to SSS.

This CBT exam system allows teachers to create their own exam questions — both objective and theory — and let students take exams on computers, just like WAEC and JAMB.

The software itself is completely free.
You are only paying for clear guidance on how to install, set up, and use it correctly in your school.
