Post-UTME Aggregate Calculator: Formulas and Examples

An aggregate score is a single number out of 100 that many universities use to rank applicants. It usually blends your UTME score, a screening or post-UTME score, and sometimes your O'level results. This guide gives you the building blocks and worked examples so you can check your numbers by hand.

One important warning first. There is no single national formula. Each university chooses its own weights and may change them from year to year. The formulas below are examples of patterns reported for some schools. Use them to understand the logic, then confirm your own school's formula in its official notice.

The general recipe

Almost every aggregate follows the same shape:

Aggregate = (UTME ÷ 400 × weight for UTME) + (post-UTME ÷ maximum × weight for post-UTME) + (O'level points ÷ maximum × weight for O'level)

The weights add up to 100. Once you know the weights, the arithmetic is simple.

Pattern 1: UTME ÷ 8 plus post-UTME ÷ 2

A widely reported pattern gives 50 points to the UTME and 50 to the post-UTME. News reports describe a formula like this for the University of Ibadan, and blogs describe variants of it for UNILAG. Here is the logic:

• UTME ÷ 8 turns a score out of 400 into a score out of 50.
• Post-UTME ÷ 2 turns a score out of 100 into a score out of 50.

Worked example. Ada scores 288 in the UTME and 74 out of 100 in the post-UTME.

• UTME part: 288 ÷ 8 = 36
• Post-UTME part: 74 ÷ 2 = 37
• Aggregate: 36 + 37 = 73

Pattern 2: UTME, post-UTME and O'level together

Several sources report a three-part blend for some universities, for example 50 per cent UTME, 40 per cent post-UTME and 10 per cent O'level. Reports for OAU describe this split, though another source gives a different description. The O'level part depends on the school's own points table for your best grades, so you must read that table in the notice.

Worked example. Chidi scores 300 in the UTME, 65 out of 100 in the post-UTME, and his O'level grades earn 7.5 out of 10 under the school's table (invented for this example).

• UTME part: 300 ÷ 400 × 50 = 37.5
• Post-UTME part: 65 ÷ 100 × 40 = 26
• O'level part: 7.5
• Aggregate: 37.5 + 26 + 7.5 = 71

Pattern 3: post-UTME marked out of a smaller total

Some schools mark the screening out of a smaller number, and some reports say the post-UTME is added as it stands. In that case you scale the UTME to its share and add the raw screening mark.

Worked example. Tola scores 270 in the UTME and 24 out of 30 in a screening test counted as 30 points, with the UTME scaled to 70 points (weights invented for this example).

• UTME part: 270 ÷ 400 × 70 = 47.25
• Screening part: 24
• Aggregate: 47.25 + 24 = 71.25

Always check how many points each part is worth. The same raw scores produce very different aggregates under different weights.

Working backwards: what do I need?

Say a school's recent cut-off for your course was 70, you scored 270 in the UTME, and the school uses Pattern 1.

• UTME part: 270 ÷ 8 = 33.75
• You need 70 − 33.75 = 36.25 from the post-UTME part.
• Post-UTME mark needed: 36.25 × 2 = 72.5 out of 100

That tells you what to practise for. Remember that cut-offs change each year and depend on the applicant pool, so treat a past cut-off as a guide and add a safety margin.

Why you should not trust a calculator blindly

• Blogs disagree. For UNILAG, sources describe different splits, including different weights for the post-UTME. For OAU, sources disagree on whether the O'level counts in the aggregate or only breaks ties. That is exactly why your own school's notice matters.
• Formulas change. A school may drop the written screening one year and use an online one the next.
• Extra eligibility rules apply. A school may require a minimum UTME score before you can even apply for screening. The University of Ibadan's 2026/2027 notice, for example, lists age, O'level and portal requirements, and says nothing here about a formula.
• The aggregate is not the whole story. Schools may also consider course quotas and catchment rules.

How to check your own numbers

1. Find your school's official post-UTME or screening notice for your session.
2. Note the maximum for each part and the weights.
3. Write the formula in one line, as in the recipe above.
4. Substitute your scores and compute by hand or with a basic calculator.
5. Compare with the school's published cut-off for your course, when available.

If the notice does not list a formula, ask the admissions office through its published contacts. Never pay a third party for an "official aggregate" or a promise of admission.

Using the result

Once you know the gap, you can plan. A 3-point gap on the post-UTME part might be closed by three weeks of focused practice. A 20-point gap needs a bigger plan, or another course. Our guide on the JAMB score you need for admission explains the wider picture, and how to prepare for post-UTME gives a study plan. School-specific pages such as UNILAG post-UTME, OAU post-UTME and UI post-UTME cover each school.

Build the marks you can control

You cannot change your UTME score now, but you can change your post-UTME mark. ExamPadi has 46,182 practice questions across JAMB, WAEC, NECO and NABTEB, with free daily practice and a Pro tier for full timed mocks. Start with the subjects your screening is likely to test using the JAMB practice hub. No tool can guarantee admission, but knowing your numbers makes your preparation sharper.
