How to Calculate Your University Aggregate Score in Nigeria 2026

How to Calculate Your University Aggregate Score in Nigeria 2026

A lot of students get confused here, and it’s honestly understandable. Your JAMB score is one thing, your Post UTME score is another — but what actually determines whether you get admitted is the aggregate. That combined number is what universities use to rank candidates and fill their available slots. Here’s how it works.

What Is an Aggregate Score?

An aggregate score is the weighted combination of your JAMB UTME score and your Post UTME score. Different universities use different formulas, but the idea is the same: neither score on its own is enough. Universities want to see how you performed on both assessments before making a decision.

Think of it this way — even if you scored 320 in JAMB but bombed Post UTME, someone who scored 280 in JAMB but aced the Post UTME could end up with a higher aggregate than you. That’s why you can’t afford to relax after JAMB.

The Two Most Common Formulas Used in Nigeria

Most Nigerian universities use one of two weighting approaches:

Formula 1: 50% JAMB + 50% Post UTME

With this formula, both scores carry equal weight. Here’s how the calculation works:

Your JAMB score is out of 400, so you first convert it to a percentage by dividing by 8. For example, a score of 280 becomes 280 ÷ 8 = 35. Then your Post UTME score (usually marked out of 100) is halved: say you scored 70, that becomes 35. Add them together: 35 + 35 = 70 aggregate.

Formula 2: 60% JAMB + 40% Post UTME

Some universities, like UNILORIN, favour JAMB more heavily. In this case:

Convert JAMB to a score out of 60 by dividing by 400 and multiplying by 60. So 280 ÷ 400 × 60 = 42. Convert Post UTME (out of 100) to a score out of 40: 70 ÷ 100 × 40 = 28. Aggregate = 42 + 28 = 70.

Which Formula Does Each University Use?

This changes periodically, so always check the university’s official website. As a general guide for 2026:

UNILAG uses a 50/50 split. UNILORIN uses 60% JAMB and 40% Post UTME. UI (University of Ibadan) has historically leaned more on JAMB. OAU uses a combination but exact weights can vary by faculty. When in doubt, calculate both ways so you’re not caught off guard.

A Practical Example

Say you scored 260 in JAMB and 65 in Post UTME. Using the 50/50 formula: 260 ÷ 8 = 32.5, plus 65 ÷ 2 = 32.5, giving you an aggregate of 65. Using the 60/40 formula: 260 ÷ 400 × 60 = 39, plus 65 ÷ 100 × 40 = 26, giving you 65 as well — in this case the same. But the numbers shift depending on your actual scores, so always run your own calculation.

What Is a Good Aggregate Score?

It depends on the course and university. For Medicine at any top federal university, you’ll generally want an aggregate of 75 and above to have a real shot. For engineering, aim for 65 and above. Social science and arts courses can be more flexible — some admit from 55 and above. The safest approach is to check the departmental cut off marks for your specific target institution.

Does O’Level Factor Into the Aggregate?

For most universities, O’Level results are a pass/fail gate rather than a scoring component. If you don’t have the right subjects and grades, you won’t even be considered — regardless of your JAMB or Post UTME scores. A few institutions do include O’Level in the aggregate formula, so again, always check the specific university’s admissions policy.

Final Tip

Don’t walk into Post UTME assuming your JAMB score will carry you. Calculate your projected aggregate before the exam, figure out the score you need in Post UTME to hit your target aggregate, and work backwards from there. That way you know exactly what you’re preparing for.
