What is a JAMB Aggregate Score?

A JAMB aggregate score combines your UTME score, Post-UTME score, and sometimes O'Level grades into a single number out of 100 that Nigerian universities use for admission screening. The formula differs by university — this calculator supports seven different formulas used by UNILAG, UI, OAU, UNN, ABU, UNIBEN and the standard formula used by most other institutions.

University Formulas Explained

  • Standard — used by most universities: (UTME ÷ 8) + (Post-UTME ÷ 2). A score of 280 in UTME and 65 in Post-UTME gives (280÷8) + (65÷2) = 35 + 32.5 = 67.5.
  • UI (University of Ibadan) — adds an O'Level component: (UTME ÷ 8) + (Post-UTME ÷ 2) + (O'Level points ÷ 10). The maximum O'Level contribution is 3.0 points from 5 A1 grades.
  • UNILAG, OAU, UNN, ABU, UNIBEN — all use the standard formula but apply their own Post-UTME cut-off thresholds for course screening.

How to Improve Your Aggregate

The UTME score carries the most weight — 1 extra point in UTME adds 0.125 to your aggregate. A 10-point improvement in UTME adds 1.25 aggregate points. For Post-UTME, 1 extra point adds 0.5 aggregate points — so Post-UTME has 4× the per-point impact of UTME. Focused Post-UTME preparation often gives the best return.

Cutoff Marks

The cutoff marks table shows minimum aggregate scores for popular courses at top universities based on recent admission cycles. Red indicates highly competitive courses (65+), orange indicates moderate competition (55–64), and green indicates more accessible courses (below 55). These are estimates — actual cutoffs vary each year with applicant numbers.

Frequently Asked Questions

Select your target university's tab — UNILAG, UI, OAU, UNN, ABU or UNIBEN. If your university is not listed, use the Standard formula which is the baseline most Nigerian universities follow. Always verify the exact formula with your institution's admissions office or official admission guidelines, as universities occasionally update their weighting.
It depends entirely on the course and university. Medicine and Law at top universities typically require 65 and above. Engineering and Sciences at most universities require 50–60. Arts and Social Sciences are often from 45–55. Education and less competitive courses may admit from 40. Check the cutoff table above for your specific combination.
The University of Ibadan considers your 5 best relevant O'Level subject grades. The grading points are: A1=6, B2=5, B3=4, C4=3, C5=2, C6=1, D7/E8/F9=0. The maximum O'Level contribution to the aggregate is 3.0 points (5 × A1 = 30 ÷ 10 = 3.0). While significant, it typically makes a difference of only 1–2 points in borderline cases.
The most common reason is using the wrong formula or the wrong Post-UTME score scale. Some universities use Post-UTME scores out of 60 or 70 rather than 100 — if your school used a different scale, adjust accordingly. Also verify whether your institution uses a separate internal formula. Always use this calculator as a guide and confirm with your institution.
It is difficult but not impossible. Universities sometimes lower cutoffs in the supplementary admission round (JAMB Supplementary) if not all spaces are filled. Changing to a less competitive course at the same university, or applying to a different university with a lower cutoff for the same course, are more reliable strategies. Check the JAMB admission portal regularly for supplementary offers.
