OAU Aggregate Score Calculator 2026: JAMB, Post-UTME and O’Level Formula

Gaining admission into Obafemi Awolowo University is a process that goes well beyond your JAMB result. OAU uses three separate components to arrive at your aggregate score: your JAMB performance, how you do in the Post-UTME screening, and the quality of your O’Level grades. Each one carries a specific weight, and understanding how they come together gives you a realistic picture of where you stand before you even apply.

This guide explains OAU’s official aggregate formula in plain terms, walks you through a worked calculation, and gives you a free calculator above so you can check your own number in seconds.

OAU’s Official Aggregate Score Formula

OAU uses what it calls a 50:40:10 grading system. The three components and their weights are:

• JAMB Score (50 percent): Your UTME result is divided by 8. Since JAMB is out of 400, dividing by 8 scales your score to a maximum of 50 points.
• Post-UTME Score (40 percent): Your screening result is entered directly and contributes up to 40 points out of 40.
• O’Level Result (10 percent): The points from your best five subject grades are added together and divided by 5, giving you a contribution out of a maximum of 10 points.

Written as a formula:

Aggregate Score = (JAMB Score divided by 8) + Post-UTME Score + (Sum of best 5 O’Level grade points divided by 5)

The maximum possible aggregate score under this formula is 100.

OAU’s O’Level Grade Point Scale

OAU uses its own grading scale to convert O’Level results into points. This scale is different from what other universities like UNILAG use, so make sure you are applying the correct numbers.

Add up the points for your best five subjects and divide that total by 5 to get your O’Level contribution. If all five grades are A1, the sum is 50, divided by 5 gives 10, which is the maximum O’Level contribution.

Two sittings are accepted with no penalty. You can take your best five subjects from either sitting, or combine results from both, with no deduction applied.

A Worked Example

Here is a full calculation using real figures:

• JAMB Score: 280
• Post-UTME Score: 32 (out of 40)
• O’Level best five grades: A1, B2, B3, C4, C5

Breaking each part down:

1. JAMB portion: 280 divided by 8 equals 35.0
2. Post-UTME portion: 32 is used directly, so 32.0
3. O’Level portion: 10 + 9 + 8 + 7 + 6 = 40, divided by 5 = 8.0

Total Aggregate Score = 35.0 + 32.0 + 8.0 = 75.0 out of 100

This is a competitive score that would place a candidate in a strong position for most OAU departments, though highly competitive courses will typically require more.

OAU’s Cut-Off Mark for 2026

For the 2026/2027 admission cycle, OAU’s general minimum JAMB cut-off mark is 200. This is the score you need just to be considered for the Post-UTME screening stage. Scoring below 200 means your application will not be processed, regardless of your O’Level grades.

To qualify for OAU’s admission process in 2026, you need to meet all of the following:

• Score at least 200 in your JAMB UTME
• Select OAU as your first choice institution (OAU does not accept second-choice candidates)
• Hold a minimum of five O’Level credits in the required subjects for your course, including English Language and Mathematics
• Be at least 16 years old at the time of application

The 200 cut-off only opens the door. Actual admission is decided by ranking candidates by their aggregate scores. Competitive courses like Medicine and Surgery, Law, and Pharmacy attract very high aggregate scores from applicants, so meeting the minimum cut-off is only the starting point.

Using This Calculator, Step by Step

1. Enter your JAMB score, out of a possible 400
2. Enter your Post-UTME score, out of a possible 40
3. Select the grade for each of your five best O’Level subjects from the dropdown menus
4. Press “Calculate My Aggregate Score” to see your result instantly

The calculator shows your total score, a colour-coded reading of where you stand, and a full breakdown of how much each component contributed.

What to Do After Calculating Your Score

Your aggregate places you in a ranking alongside everyone else who applied for the same course at OAU. A higher score improves your chances, but admission also depends on several factors you should keep in mind:

• The number of applicants competing for your specific course
• The total spaces available in that department for the year
• How your aggregate compares to candidates with stronger individual components

If your score is not where you need it to be, you have a few options worth considering. You could switch to a related course at OAU with less competition, look into JUPEB or IJMB as a route to reapply with a stronger academic profile, or compare your score against other universities in our calculator section to find a realistic alternative.

Frequently Asked Questions

What is the minimum JAMB score to apply to OAU in 2026?

The minimum is 200. Candidates who score below this are not eligible for OAU’s Post-UTME screening, regardless of their O’Level results or any other factors.

Is OAU’s Post-UTME score out of 40 or out of 100?

For the aggregate calculation, OAU’s Post-UTME score contributes directly out of 40, since it represents 40 percent of the final score. Some sources describe it differently because OAU may administer the exam on a different raw scale and scale it internally, but the number that enters the formula is out of 40.

Does OAU penalise candidates who sat O’Level exams twice?

No. OAU allows you to combine your best five subjects from one or two sittings without any deduction. You simply pick your strongest five grades, from whichever sitting they came.

Can I get into OAU if I only just meet the 200 cut-off?

Meeting 200 qualifies you for screening but does not guarantee admission. For most courses at OAU, the practical aggregate scores of successful candidates are considerably higher than the general minimum. The competition is especially intense in faculties like Science, Law, and Social Sciences.

Does OAU accept second-choice applications?

No. OAU has a firm policy of not admitting candidates who listed it as a second choice during JAMB registration. You must set OAU as your first choice institution for your application to be considered.
