Most candidates don’t miss admission because they aren’t clever enough — they miss it to avoidable mistakes. Here are the ones that cost admission every year, grouped by stage, with the fix for each.
Registration mistakes
- NIN / name / date-of-birth mismatch. JAMB relies on your NIMC data — fix any mismatch at NIMC before registering.
- Using a phone number or email you don’t control, or letting an agent hold your details. Own your profile.
- Registering at an unaccredited centre. Only use accredited CBT centres. Fixes for profile/registration issues are in the Problem Solver.
Subject and course mistakes
- The wrong subject combination — the single most common admission-killer. Confirm yours with the Subject Combination Checker.
- Choosing a course by friends or prestige instead of fit and cut-off — see choosing a course you won’t regret.
- O’Level that doesn’t match the course — right UTME subjects, wrong credits, still disqualifies you.
Preparation mistakes
- Reading without the syllabus — you waste time on untested material. Use the Study Centre and the high-yield topics.
- Skipping CBT practice — books alone never build exam speed. Practise free on Belmadeng CBT.
- Ignoring Use of English — it’s 60 of your 180 questions.
- Cramming late and never doing a mock. Start early with the 3-month plan.
Exam-day mistakes
- Bringing a prohibited item (phone, watch, calculator) — instant disqualification. See the exam-day checklist.
- Poor time management — getting stuck on hard questions. Use the two-pass method.
- Leaving questions blank — there’s no negative marking, so always guess.
- Arriving late and missing biometric verification.
Post-exam and admission mistakes
- Not uploading O’Level to CAPS — you’re flagged ineligible even with a great score.
- Missing Post-UTME — no registration, no consideration. See Post-UTME explained.
- Not monitoring or accepting your offer on CAPS — unaccepted offers expire. Follow the next-steps map.
- Falling for "expo" or paid "runs" — a crime that cancels results. See avoid JAMB scams.
The one habit that avoids most of them
Nearly every mistake here comes down to two things: starting late and not checking the official process. Start early, confirm each step against JAMB’s official channels, and use the free tools linked above — and you’ll sidestep the traps that catch thousands of candidates every year.
