AUN cut off mark for Microbiology 2026/2027

The 2026 UTME cut-off for Microbiology at AUN stands at 238. Among the 49 institutions offering Microbiology in our guide, AUN ranks 5th by cut-off, placing the programme in the upper half of national competitiveness for the course.

Compared to 2025, the figure climbed by 4 points, reflecting the stronger national candidate pool and rising demand for the course at AUN.

Clearing 238 at UTME is the threshold to be considered, not a guarantee of admission. The post-UTME or screening aggregate decides who actually gets the place. A typical aggregate for Microbiology at AUN that secures an offer sits broadly in the 71.8+ range on the 100-point scale, though the exact threshold moves year to year with applicant volume.

American University of Nigeria uses the standard Nigerian aggregate model for Microbiology: a weighted blend of UTME score, post-UTME or screening result, and O'level grade points. The most common federal-university split is 50% UTME, 30% post-UTME, 20% O'level, scaled to a 100-point aggregate.

Worked example: a candidate with a UTME of 250 (= 31.25 of 50), a post-UTME score of 65 of 100 (= 19.5 of 30) and five A1 grades at O'level (= 20 of 20) finishes on an aggregate of 70.75, comfortably above typical Microbiology thresholds at most institutions. A weaker O'level pulls the number down materially, which is why many candidates underestimate the role of secondary-school results in the admission decision.

Each component matters in proportion to its weight. UTME at 50% remains the largest single component, but post-UTME at 30% is enough to lift or sink an otherwise borderline application. O'level grades at 20% reward consistent strength across the school years.

Private institutions like AUN sometimes diverge from the 50-30-20 split, using an internal aptitude test or interview instead of a points-based post-UTME. The principle remains the same: a single component cannot redeem a weak overall profile, and candidates should prepare for every stage of the screening.

A realistic plan for Microbiology at AUN starts with a UTME target above the cut-off, not at the cut-off. Aim for 253+, which gives a comfortable margin and protects against last-minute rises in the cut-off. Candidates who score exactly at the cut-off are often squeezed out by post-UTME aggregates, because higher-scoring candidates rank above them on the final list.

Post-UTME performance matters as much as the UTME score. Even a candidate at 253+ needs a strong post-UTME to translate eligibility into admission. Past papers, focused revision of the post-UTME syllabus and timed practice are the standard preparation.

If 238 looks out of reach, consider second-choice institutions for the same course at lower cut-offs in this guide, or related courses at AUN with lower cut-offs. The change-of-course window during the cycle is the formal route to switch, and many candidates use it to recover from a UTME score that fell short of the first-choice target.

The cut-off has risen against 2025, so plan with the assumption that the 2027 cycle could push it further upward. Confirm the official AUN admission portal for any mid-cycle adjustments before paying any fees.
