How to Calculate OAU Aggregate Score for 2025

Obafemi Awolowo University, popularly referred to as OAU, is a premier federal university located in Ile-Ife, Osun State, Nigeria.

It was founded in 1961 as the University of Ife but was later renamed Obafemi Awolowo University on May 12, 1987, under the administration of Ibrahim Badamasi Babangida, in honour of Chief Obafemi Awolowo, the first premier of the Western Region of Nigeria.

OAU is one of the top 10 universities in Nigeria and has become one of the most sought-after institutions in recent years.

The university has a strong reputation for academic excellence and a solid educational foundation.

OAU offers a wide range of undergraduate programs, and admission into the school is highly competitive.

OAU’s admission process is influenced by several factors, including:

• JAMB UTME Score
• Post UTME Score
• O-level Results
• Aggregate Score
• Catchment Area and Educationally Less Developed States (ELDS)

OAU aggregate score, also known as the weighted average score, is the final admission score used by Obafemi Awolowo University (OAU) to admit students into various courses and departments.

This score is gotten by combining the UTME, O level, and Post UTME scores.

This single score determines whether a candidate qualifies for admission into their chosen course.

Courses like medicine, law, engineering, and pharmacy often demand aggregate scores above 70%.

It’s very important to know how to calculate your aggregate score just so as to know your chances of admission before the school starts its admission process; this would enable you to make timely decisions.

Here is a step-by-step guide on how to calculate your aggregate score at Obafemi Awolowo University (OAU).

Note: Aggregate Score or Average Score

How to Calculate OAU Aggregate Score for 2025

Obafemi Awolowo University (OAU) uses a 50:40:10 grading system in calculating their aggregate score:

• UTME (JAMB): 50% (calculated by dividing your UTME score by 8)
• Post‑UTME Screening: 40% (Post‑UTME score divided by 2)
• O’Level Results: 10% (graded and averaged over five core subjects)

So, the formula becomes:

Aggregate Score = (UTME ÷ 8) + (Post‑UTME ÷ 2) + (Average O’Level points over 5 subjects)

Example:

Let’s say Olusegun scored 304 in the JAMB UTME.

His UTME score would be:

304 ÷ 8 = 38% out of 50%.

Now, let’s also assume Olusegun scored 30 out of 40 in his Post‑UTME exam, and his five relevant O’Level subjects are as follows:

1. English – A1
2. Mathematics – B3
3. Chemistry – A1
4. Physics – B3
5. Biology – A1

OAU Grading System for O’Level:

• A1 = 10
• B2 = 9
• B3 = 8
• C4 = 7
• C5 = 6
• C6 = 5

So, Olusegun’s O’Level score would be:

1. English (A1) = 10
2. Mathematics (B3) = 8
3. Chemistry (A1) = 10
4. Physics (B3) = 8
5. Biology (A1) = 10

Total = 10 + 8 + 10 + 8 + 10 = 46

Now divide by 5:

46 ÷ 5 = 9.2%

Final Calculation:

UTME Score = 38%

Post‑UTME Score = 30%

O’Level Score = 9.2%

Olusegun’s Aggregate Score = 38% + 30% + 9.2% = 77.2%

OAU general admission requirements

• Candidates must sit for the JAMB UTME exams and score at least 200 in JAMB to be eligible for the school’s Post UTME process.

How to Improve Your Aggregate Score in OAU

Improving your aggregate score increases your chances of gaining admission into competitive courses like medicine, law, nursing, and accounting.

Below are things you need to do if you want to improve your aggregate score and chances of admission.

• Aim for a High JAMB UTME Score

Since JAMB contributes 50% to your aggregate, a high UTME score gives you a very strong advantage, especially for those going for competitive courses. Target at least 270 above.

• Prepare Thoroughly for the Post‑UTME

The Post‑UTME makes up 40% of your aggregate score.

Even if your JAMB score isn’t very high, a strong Post‑UTME performance can make up for it.

Study OAU Post UTME past questions, understand the pattern of their questions, and improve your speed and accuracy.

Start your preparation early, if possible, immediately after your JAMB UTME exams.

• Have very good O-level grades

Even though your O level just has 10% for your aggregate, a poor O level can drastically affect your aggregate.

Try to get A1 to B3 in your core subjects such as English, mathematics, and subjects relevant to your course.

If your grades are low, consider using a better sitting or combining results from two exams (e.g., WAEC + NECO), if allowed.

• Choose the Right Course Strategically

Sometimes, your passion and your current academic strength may not align. If your score isn’t competitive enough for medicine, for example, you may consider related but less competitive alternatives like physiology, medical rehabilitation, biochemistry, etc.

Later, you may apply for a change of course or department if you get a very good CGPA.

• Avoid Common Mistakes

Double-check your JAMB subject combination to avoid disqualification.

Upload your O’Level results on JAMB CAPS early.

Attend the Post‑UTME exam and submit all required documents within deadlines.

Final Tip

Start early. Don’t wait until when the post-UTME form is out before you start preparing for your post-UTME exams.

Conclusion

OAU is a very competitive school, so knowing how to calculate your aggregate score would enable you to make timely decisions, especially if you feel you didn’t do well in your UTME.

So, it’s important to calculate your aggregate score on time so as to make the right decisions concerning your choice of course.
