Whether you passed or not, you know something a new candidate doesn’t: where the centre is and how to get there.

Every year, candidates get lost, arrive late, or overpay transport because nobody told them what the centre was really like. You can fix that in 1 minute.

We only need the centre name, town, address, and transport fare. No score, no judgment. 👉 Add your JAMB centre (takes 1 minute).
