Getting admission into a Nigerian university is more than just passing your JAMB UTME. Each institution uses an aggregate score system to determine who qualifies for admission into various departments. If you’ve ever wondered how universities calculate aggregate scores, this guide breaks it down in clear and simple terms.

How to Calculate Aggregate Score

What Is an Aggregate Score?

An aggregate score is the final score used by universities to determine a candidate’s eligibility for admission into a chosen course. It combines your UTME (JAMB) score and your Post-UTME or screening score, and sometimes your O’Level (WAEC/NECO) results.

Each school has its unique formula for calculating the aggregate score, so understanding how it works helps you know your admission chances early.

Why Is Your Aggregate Score Important?

Your aggregate score:

• Determines whether you meet your department’s cut-off mark

• Helps you compare your score to others in your chosen course

• Increases your chance of getting admitted faster through merit lists

Knowing your aggregate helps you make smart choices when applying for admission or considering a change of course or institution.

How to Calculate Aggregate Score  

Different universities in Nigeria have different systems for calculating aggregate scores. Let’s go through the most popular methods:

Method 1: For Schools That Use UTME and Post-UTME

This is the most common method used by universities like University of Benin (UNIBEN), University of Lagos (UNILAG), and others.

Formula:

Aggregate Score = UTME Score​/8 + Post-UTME Score​/2

Example:

• UTME score = 240

• Post-UTME score = 70

Aggregate=240/8 + 70/2 = 65

So, your final aggregate score is 65%.

Method 2: For Schools That Use UTME, Post-UTME, and O’Level

Some universities such as University of Ibadan (UI) and Obafemi Awolowo University (OAU) consider O’Level results alongside JAMB and Post-UTME scores.

Example Formula (UI Style):

• UTME = 50%

• Post-UTME = 30%

• O’Level (best 5 subjects) = 20%

Let’s assume:

• UTME score = 250 → 50% of that = 31.25

• Post-UTME score = 70 → 30% of that = 21

• O’Level = all A1 → 20%

$$\text{Aggregate}=31.25+21+20=72.25\%$$

Final aggregate score: 72.25%

Method 3: For Schools Using JAMB and O’Level Screening Only (No Post-UTME)

Some polytechnics and universities (like Lagos State University, LASU) use a screening system instead of Post-UTME.

They calculate based on:

• JAMB score (converted to 50%)

• O’Level grades (converted to 50%)

Example (LASU Style):

Aggregate = (JAMB Score/8) + O’Level Grade Points

So if:

• JAMB = 240 → 30 points

• O’Level = 16 points (based on grade conversion)

$$\text{Aggregate}=30+16=46\%$$

Your final aggregate score is 46%.

O’Level Grade Point System Example

Many schools use a grade point system for calculating O’Level results. Here’s a common scale:

Only the best five subjects relevant to your course are used.

So if you have A1, B2, B3, C4, and C5 → 6 + 5 + 4 + 3 + 2 = 20 points

How to Know Your Chances of Admission

After calculating your aggregate:

1. Compare it with your departmental cut-off mark.

2. If your aggregate is higher, you have a strong admission chance.

3. If it’s slightly below, you may still be considered in supplementary lists.

4. If it’s much lower, consider applying for a change of course or institution.

Tips to Improve Your Aggregate Score

1. Aim high in JAMB: Since UTME carries the largest weight, target 250 and above.

2. Prepare well for Post-UTME: Practice past questions and timing.

3. Get strong O’Level grades: Focus on your core five subjects.

4. Avoid guessing in exams: Wrong answers reduce your score accuracy.

5. Apply early for Post-UTME: Late registration can affect your screening process.

Frequently Asked Questions About How to Calculate Aggregate Score

1. What is the minimum aggregate score for university admission?

It depends on the institution and course, but generally, 50% and above gives you a good chance for most universities.

2. Do polytechnics calculate aggregate scores the same way as universities?

Not exactly. Polytechnics may place more weight on your O’Level and JAMB scores, and most don’t conduct Post-UTME exams.

3. Does my state of origin affect my aggregate score?

No, your aggregate is based purely on performance. However, catchment area can affect final admission decisions.

4. How do I calculate my aggregate if I didn’t write Post-UTME?

Your school will likely use a screening formula that combines your JAMB and O’Level scores.

5. Can I gain admission with a low aggregate score?

Yes, if you apply for courses with lower departmental cut-offs or in institutions with less competition.

Final Thoughts

Understanding how to calculate your aggregate score for university admission helps you stay ahead of the competition.
