How to Calculate UNILORIN Aggregate Score for 2026/2027
Published: September 29, 2026 | Source: CampusAI News
📌 Overview
If you applied to the University of Ilorin (UNILORIN) for the 2026/2027 academic session, your UTME score is only one part of the admission calculation.
According to UNILORIN's official 2026/2027 pre-admission screening instructions, admission is based on three components:
- UTME/A-Level score — 50%
- Post-UTME screening score — 30%
- Five relevant O'Level grades — 20%
This means the total aggregate is calculated over
100 points.
> Official formula: 50% UTME/A-Level + 30% Post-UTME + 20% O'Level
📊 Official UNILORIN Aggregate Formula
| Component | Weight | Maximum Contribution |
|---|---:|---:|
| UTME or A-Level score | 50% | 50 points |
| Post-UTME screening score | 30% | 30 points |
| Five relevant O'Level grades | 20% | 20 points |
| Total | 100% | 100 points |
The official UNILORIN 2026/2027 screening instructions state that the offer of admission will be based on this aggregate calculation.
🧮 How to Calculate the UTME Contribution
UTME is scored out of 400, while its contribution to the UNILORIN aggregate is a maximum of 50 points.
Therefore:
UTME contribution = UTME score ÷ 8
Example
If your UTME score is 280:
280 ÷ 8 = 35
Your UTME score contributes 35 points out of 50 to your aggregate.
Another example:
240 ÷ 8 = 30
A UTME score of 240 contributes 30 points.
📝 How to Calculate the Post-UTME Contribution
The Post-UTME screening component carries a maximum of 30 points.
The calculation is:
Post-UTME contribution = Post-UTME score × 0.30
Example
If your Post-UTME score is 70:
70 × 0.30 = 21
Your Post-UTME score contributes 21 points out of 30.
If your score is 60:
60 × 0.30 = 18
Your Post-UTME contribution would therefore be 18 points.
🎓 How the O'Level Contribution Works
UNILORIN allocates 20 points to the candidate's five relevant O'Level grades.
The official 2026/2027 screening instructions confirm the 20% weighting.
However, candidates should be careful when manually assigning O'Level points.
The official document confirms the 20% contribution, but candidates should use the O'Level conversion displayed during the official screening process rather than assuming that an unofficial grade conversion applies.
For an illustrative example only, if a candidate's verified O'Level contribution is 16 out of 20:
O'Level contribution = 16 points
📊 Worked UNILORIN Aggregate Example
Assume a candidate has:
- UTME: 280
- Post-UTME: 70
- Verified O'Level contribution: 16/20
The calculation would be:
| Component | Calculation | Contribution |
|---|---:|---:|
| UTME | 280 ÷ 8 | 35 |
| Post-UTME | 70 × 0.30 | 21 |
| O'Level | Verified value | 16 |
| Aggregate | 35 + 21 + 16 | 72/100 |
🎯 Estimated Aggregate: 72/100
This example shows how the official weighting is applied.
It does not mean that a candidate with 72/100 is automatically guaranteed admission.
Admission can still depend on the candidate's chosen programme, available spaces, eligibility requirements and the university's final admission process.
⚠️ One-Sitting O'Level Requirement for Selected Programmes
UNILORIN's 2026/2027 screening information states that candidates applying for certain programmes must present an O'Level result obtained at one sitting.
These include:
- Medicine and Surgery
- Pharmacy
- Optometry and Vision Science
- Computer Engineering
Candidates applying for these programmes should ensure that they meet the applicable O'Level requirements before relying on an aggregate calculation.
