How Post-UTME Aggregate Scores Are Calculated

By JAMB Advisor Editorial · 11 Nov 2026

After the UTME, most universities run a screening exercise. Your final admission ranking is usually based on an aggregate score that combines your UTME score with screening results and, at some schools, your O'Level grades. Knowing your school's formula tells you how much the Post-UTME matters for you.

Formulas vary by institution and can change from year to year. Always confirm your school's current formula on its official admission notice. The examples below are for illustration.

Formula 1: UTME and Post-UTME, 50:50

This is a widely used approach.

  • UTME part: UTME score ÷ 8 (turns 400 into 50)
  • Post-UTME part: screening score converted to a mark out of 50
  • Aggregate: UTME part + Post-UTME part = score out of 100

Example: UTME 264, Post-UTME 70/100.

  • UTME part: 264 ÷ 8 = 33
  • Post-UTME part: 70 ÷ 2 = 35
  • Aggregate: 68

Formula 2: UTME, Post-UTME and O'Level

Some universities give O'Level grades their own weight, for example UTME 50%, Post-UTME 30%, O'Level 20%.

  • UTME part: UTME ÷ 8 = out of 50
  • Post-UTME part: screening converted to out of 30
  • O'Level part: points for grades in the five relevant subjects, converted to out of 20 (an A1 earns more points than a C6)

Example: UTME 240, Post-UTME 60/100, O'Level points 16/20.

  • UTME: 240 ÷ 8 = 30
  • Post-UTME: 60 × 0.3 = 18
  • O'Level: 16
  • Aggregate: 64

Formula 3: UTME and O'Level only (no written test)

Some institutions screen without a written exam, using UTME and O'Level grades. In that case your O'Level grades — and the number of sittings — become very important.

What this means for you

  • If your UTME score is modest, a strong Post-UTME performance can lift your aggregate significantly under a 50:50 formula.
  • If your school weights O'Level, your grades already count before screening — A's and B's give you a head start.
  • If your school uses only UTME and O'Level, there is no test to "make up" with, so choose the school with that in mind.

How departmental cut-offs relate to aggregates

Universities usually announce departmental cut-offs as aggregates (for example, "Medicine: 75"). Work backwards: if you know the formula and your UTME score, you can estimate the Post-UTME score you need.

Example: Target aggregate 70, formula 50:50, UTME 256.

  • UTME part: 256 ÷ 8 = 32
  • You need 70 − 32 = 38 out of 50 in Post-UTME, i.e. 76/100
