UNN Post-UTME: Screening Format, Aggregate & How to Prepare
For the 2026/2027 admission cycle, UNN screens candidates with a computer-based test (CBT), not an O’level-only review. The test covers the same four subjects you registered for in JAMB — 15 questions per subject, 60 questions in total, answered in 60 minutes. Your JAMB score is then combined with this screening score to produce an aggregate, which decides your course of study.

How the aggregate is calculated
UNN combines your JAMB score with your screening performance, but the exact weighting has not been consistent from one admission cycle to the next. In the 2025/2026 cycle, when UNN ran an O’level-only screening (no written exam), reports put the split at 90% JAMB to 10% O’level-derived score. For a cycle where a written CBT is conducted, some sources describe a straight average — JAMB and screening scores weighted equally. Because this figure genuinely varies by year and isn’t something a blog can safely fix in stone, treat any specific percentage you read online as provisional and confirm the weighting UNN publishes on your result slip or portal for this cycle.
What has stayed constant across cycles is the exam structure itself where a CBT is used: four subjects, 15 questions each, 60 minutes. To illustrate how an average-based aggregate works (one method UNN has used when a written test is conducted): if your JAMB score is 237 and you score 33 out of 60 in the screening (converted proportionally to a score out of 400, roughly 220), a simple average gives (237 + 220) ÷ 2 = 228.5. Your actual formula and cut-off for admission into your course will be confirmed by UNN’s admission office — use this only to understand the mechanics, not to predict your outcome.
What the screening contains and how to prepare
The test is drawn from your four UTME subjects, so if you sat English, Mathematics, Biology and Chemistry for JAMB, expect 15 questions from each of those — not a fresh set of subjects. Pacing is the main challenge: 60 questions in 60 minutes leaves roughly one minute per question, and candidates who freeze on an early question tend to run out of time later.
Bring your JAMB result slip and online acknowledgement slip to the venue — you’ll need both for accreditation before you’re issued a passcode to log into the CBT system. Practical prep advice:
- Revise your weakest of the four subjects first — a 15-question block in a subject you’re shaky on costs more than reinforcing one you already know.
- Practise on a timer. Untimed revision hides the pacing problem until exam day.
- Redo your JAMB syllabus topics rather than hunting for “leaked” material — the screening draws from the same UTME syllabus, not new content.
- Arrive early. CBT centres process candidates in batches, and accreditation queues eat into your rest time if you’re late.
Admission requirements
Beyond the screening score, UNN’s general requirement is five O’level credits, including English Language and Mathematics, obtained at not more than two sittings — the exact subject combination depends on your faculty and department. Your UTME subjects must also match what your intended course requires (for example, Mathematics, Physics and Chemistry for most Engineering and Physical Science courses; Literature in English and a related arts subject for Arts and Humanities courses). Because faculty-by-faculty requirements run into dozens of departments and change from one prospectus to the next, we won’t reproduce a full table here — check the current combination for your specific course on UNN’s official admission portal (unnportal.unn.edu.ng) and cross-check your UTME subject registration against JAMB’s Institution Brochure and Admission Subject Combination System (IBASS on jamb.gov.ng) before you register.
Practise with real past questions
Our UNN Post-UTME practice pack is built to match this exact CBT format — 60 questions across your four JAMB subjects, so you’re drilling the format, not guessing at it.
