How Nigerian Aggregate Scores Work

Most Nigerian federal universities combine your JAMB score with a Post-UTME (or screening) result to give an aggregate out of 100. Some additionally factor in your O'Level grades.

Common Formulas

  • UNILAG, UNN, FUTA, ABU, LASU: (JAMB ÷ 8) + (Post-UTME ÷ 2) — 50/50 weight, no O'Level component.
  • University of Ibadan (UI): JAMB out of 60% + Post-UTME out of 30% + O'Level out of 10%.
  • OAU: (JAMB ÷ 8) + (Post-UTME ÷ 2) — published as 50/50.
  • UNILORIN: (JAMB ÷ 8) + (Post-UTME ÷ 2). Cutoff is usually published as JAMB only.
  • Private universities (Covenant, Babcock): Internal screening replaces Post-UTME, formulas vary.

Always verify the formula on the school's official Post-UTME brochure before relying on the number.

Use your target institution's exact formula Aggregate formulas vary materially across institutions. Calculating with the wrong formula can produce a misleading number โ€” verify by selecting your specific institution before reading the result.

What aggregate score actually is

The aggregate score is a composite number that Nigerian universities compute by combining your JAMB UTME score, your Post-UTME screening score, and (at some institutions) your O\'Level credits. Admission to each course is then offered to the top candidates by aggregate, course by course, until the quota fills.

The aggregate is the practical filter that decides admission. The JAMB cut-off lets you be considered; the institutional cut-off lets you sit Post-UTME; the departmental cut-off lets you be ranked; the aggregate ranks you against everyone else who also cleared all three cut-offs. The candidate with the higher aggregate gets admitted; the candidate with the lower aggregate moves to the next list or the next cycle.

How major Nigerian universities calculate aggregate

Each Nigerian university publishes its own aggregate formula. The most common patterns:

  • University of Lagos (UNILAG): 50% UTME (UTME score รท 8) + 50% Post-UTME (Post-UTME score รท 2). Maximum aggregate 100.
  • University of Ibadan (UI): 50% UTME รท 8 + 50% Post-UTME รท 2. Maximum 100. Some courses add O\'Level grade-point conversion as a tiebreaker.
  • Obafemi Awolowo University (OAU): 60% UTME + 40% Post-UTME (each scaled to 100). Maximum 100.
  • University of Nigeria, Nsukka (UNN): 50% UTME รท 8 + 50% Post-UTME รท 2. Maximum 100.
  • Ahmadu Bello University (ABU): 50% UTME + 30% Post-UTME + 20% O\'Level grade conversion. Maximum 100.
  • Bayero University Kano (BUK): Similar three-component formula with O\'Level weighting.
  • Federal University of Technology, Akure (FUTA): 60% UTME + 40% Post-UTME. Maximum 100.
  • University of Benin (UNIBEN), University of Ilorin (UNILORIN), University of Port Harcourt (UNIPORT): 50% UTME + 50% Post-UTME with various scaling adjustments.

Always verify the exact current formula on the institution\'s admission portal for the cycle you are applying in. Formulas occasionally change between cycles.

O\'Level conversion in aggregate formulas

Institutions that include O\'Level grades in the aggregate use point-conversion tables. The typical conversion:

  • A1: 8 points.
  • B2: 7 points.
  • B3: 6 points.
  • C4: 5 points.
  • C5: 4 points.
  • C6: 3 points.

The five subjects relevant to your course are summed (maximum 40 points), then scaled to the institution\'s aggregate weighting (typically 20% of the aggregate at ABU and BUK).

How to use this calculator

  1. Select your target institution from the dropdown. The calculator switches to that institution\'s verified formula automatically.
  2. Enter your UTME score (out of 400).
  3. Enter your Post-UTME score (out of the institution\'s Post-UTME maximum, typically 100, 50 or 30 depending on the institution).
  4. If applicable, enter your O\'Level grades for the five subjects relevant to your course.
  5. The calculator outputs: your aggregate score, the competitive band for your target course, and an estimated admission probability based on recent admission data.

Strategy โ€” what aggregate tells you

Three patterns matter for using your aggregate strategically:

  • Aggregate predicts competitiveness, not absolute admission. Your aggregate determines where you rank against other applicants for the same course at the same institution. A 75 aggregate at UNILAG Medicine may not admit (because the cohort cut-off is 78); the same 75 at a less competitive university for the same course may comfortably admit.
  • Strong UTME + weak Post-UTME = unstable aggregate. The 50/50 weighting at most institutions means a weak Post-UTME drags down even a strong UTME. Candidates with 320 UTME but 30 Post-UTME often miss admission to courses that would have been comfortable with 280 UTME + 70 Post-UTME.
  • Recent admitted scores are the true filter. The cut-off published by the institution is the floor; the actual admitted aggregate is typically 30โ€“60 points higher for competitive courses. Use the admission checker for realistic probability assessment.

How to improve your aggregate

  • Strengthen Post-UTME preparation. Post-UTME contributes 40โ€“50% of the aggregate at most institutions. Drilling institution-specific past questions has substantial aggregate impact.
  • Plan your O\'Level subjects strategically (for institutions where O\'Level weights into aggregate). Strong grades in the five course-relevant subjects can lift aggregate by 5โ€“10 points.
  • If retaking UTME, target the 240โ€“280 band for competitive courses. The marginal aggregate impact of pushing UTME from 260 to 290 is substantial; from 290 to 310 less so.
  • Consider applying to multiple institutions where your aggregate is comfortable. The same aggregate may be borderline at UNILAG Medicine and comfortable at less competitive institutions for the same course.

Frequently Asked Questions

How is aggregate score calculated at UNILAG?
50% UTME score (UTME รท 8) + 50% Post-UTME score (Post-UTME รท 2) = maximum aggregate of 100. A 280 UTME plus 80 Post-UTME at UNILAG gives an aggregate of (280รท8) + (80รท2) = 35 + 40 = 75.
Does O'Level grade affect my aggregate score?
At ABU, BUK and several other institutions, yes. O'Level grades are converted to points (A1=8, B2=7, B3=6, C4=5, C5=4, C6=3) summed across the five course-relevant subjects, and weighted into the aggregate (typically 20%). Most southern Nigerian universities do not weight O'Level into aggregate.
What is a good aggregate for Medicine in Nigeria?
At top federal universities (UNILAG, UI, OAU, ABU, UNN), competitive Medicine aggregate runs 78โ€“85+ on the 100-point scale. The published cut-off may be lower but the actual admitted aggregate is typically that high.
Can I be admitted with an aggregate below the published cut-off?
No. The published cut-off is the absolute floor โ€” applications below it are rejected at first review. Higher aggregates clear the cut-off and proceed to ranked aggregate-based admission.
How accurate is the aggregate calculator?
For institutions where we maintain the verified formula, 100% accurate โ€” the calculator implements the exact formula the institution publishes. For institutions where formulas change cycle to cycle, verify the current cycle's formula on the institution's admission portal.
Why do different universities have different aggregate formulas?
Each institution sets its own admission framework based on its NUC quota allocation, candidate-pool characteristics, and historical performance patterns. The Federal Government does not mandate a single formula.
