How to Calculate Aggregate Score for Nigerian Universities is one of the most important things every admission seeker should understand before applying for admission in the 2026/2027 academic session. Whether you are applying through UTME or Direct Entry screening, knowing how your aggregate score is calculated helps you determine your chances of gaining admission into your preferred university and course.
Many students score high in JAMB but still miss admission because they do not understand how universities calculate aggregate scores. Others perform well in Post-UTME but fail to combine their scores correctly.
In this detailed guide, you will learn How to Calculate Aggregate Score for Nigerian Universities, the different methods used by federal, state, and private universities, examples of aggregate calculations, important factors that affect your score, and tips for improving your admission chances.
What Is an Aggregate Score?
An aggregate score is the final score a university uses to rank candidates for admission. Instead of relying only on your UTME score, most universities combine two or more of the following:
- JAMB UTME score
- Post-UTME score
- O’Level results (WAEC, NECO, or NABTEB)
- Screening performance (for schools without Post-UTME)
The final aggregate score determines whether you meet the admission requirement for your chosen course.
Every university has its own formula. This is why understanding How to Calculate Aggregate Score for Nigerian Universities is very important before admission lists are released.
Why Aggregate Score Is Important
Your aggregate score is often more important than your JAMB score alone.
For example:
- Student A scores 310 in JAMB but performs poorly in Post-UTME.
- Student B scores 270 in JAMB but scores very high in Post-UTME.
Depending on the university’s formula, Student B may have a higher aggregate score and stand a better chance of admission.
This explains why students should never rely solely on UTME performance.
How to Calculate Aggregate Score for Nigerian Universities
There is no single formula used by all universities in Nigeria.
Generally, institutions use one of these methods:
Method 1: JAMB Percentage + Post-UTME Percentage
This is the most common method.
Step 1
Convert your JAMB score to 50%.
Formula:
JAMB Score ÷ 8
Example:
JAMB Score = 280
280 ÷ 8 = 35
Step 2
Convert your Post-UTME score to 50%.
If your Post-UTME is over 100:
Post-UTME Score = 72
72 ÷ 2 = 36
Step 3
Add both scores.
35 + 36 = 71
Your aggregate score is 71.
Method 2: JAMB and Post-UTME Added Directly
Some universities simply assign equal percentages.
Example:
JAMB = 260
Convert:
260 ÷ 8 = 32.5
Post-UTME = 68
68 ÷ 2 = 34
Aggregate:
32.5 + 34 = 66.5
Method 3: Universities That Use O’Level Grades
Some universities include your O’Level performance.
Typical grading:
- A1 = 6 points
- B2 = 5 points
- B3 = 4 points
- C4 = 3 points
- C5 = 2 points
- C6 = 1 point
Suppose your five relevant subjects are:
- English – B2 = 5
- Mathematics – A1 = 6
- Biology – A1 = 6
- Chemistry – B3 = 4
- Physics – B2 = 5
Total:
5 + 6 + 6 + 4 + 5 = 26 points
Some universities combine these points with your JAMB score to obtain your final aggregate.
Always check your institution’s admission guidelines before calculating.
Universities Without Post-UTME
Some universities no longer conduct written Post-UTME examinations.
Instead, they rely on:
- JAMB score
- O’Level grades
- Online screening
For such institutions, the aggregate score is calculated differently.
For example, the university may allocate:
- 60% for JAMB
- 40% for O’Level
The exact formula varies from one institution to another.
Aggregate Score Calculation for Popular Nigerian Universities 2026/2027
Since every institution adopts its own admission policy, understanding how individual universities calculate aggregate scores is essential. Below are some of the common methods used by popular Nigerian universities. Always confirm the latest screening guidelines when your preferred institution releases its admission information.
1. University of Lagos (UNILAG)
UNILAG typically uses a combination of your UTME score and O’Level performance to determine your aggregate score. The university may update its admission formula from one admission cycle to another, so candidates should carefully read the official admission guidelines before calculating their scores.
If you are applying to UNILAG, ensure your O’Level grades are strong because they can significantly influence your final aggregate.
2. Obafemi Awolowo University (OAU)
OAU has previously used a formula that combines your JAMB score with your Post-UTME performance. Candidates with excellent scores in both examinations usually stand a better chance of securing admission into competitive courses like Medicine, Law, Pharmacy, and Nursing.
3. University of Nigeria, Nsukka (UNN)
UNN may combine your JAMB score, Post-UTME score (where applicable), and O’Level results depending on the admission policy for the particular session.
Applicants should avoid relying on old formulas, as admission requirements may change.
4. Ahmadu Bello University (ABU)
ABU often considers candidates based on their UTME performance and screening exercise. The university may not always conduct a written Post-UTME examination, depending on the admission year.
Students should ensure all their O’Level results are correctly uploaded before admission processing begins.
5. University of Benin (UNIBEN)
UNIBEN has traditionally conducted Post-UTME examinations and combines candidates’ performances to determine aggregate scores.
Scoring high in both JAMB and Post-UTME gives applicants a better chance of gaining admission into highly competitive programmes.
6. Lagos State University (LASU)
LASU may include UTME performance, O’Level grades, and screening results when calculating aggregate scores.
Because admission into LASU is highly competitive, especially for courses like Medicine, Nursing, Accounting, and Law, applicants should aim for excellent scores across all admission requirements.
7. Federal University of Technology, Minna (FUTMINNA)
FUTMINNA uses its own admission screening method, which may involve JAMB scores and other admission criteria.
Engineering, Computer Science, and other technology-based programmes often require higher aggregate scores due to competition.
8. Nnamdi Azikiwe University (UNIZIK)
UNIZIK periodically reviews its admission screening process. Candidates are advised to calculate their aggregate only after the university publishes its official screening guidelines for the admission year.
9. University of Ilorin (UNILORIN)
UNILORIN is one of Nigeria’s most competitive universities. Depending on the admission session, the university may use JAMB scores and online screening information when assessing candidates.
Applicants should pay close attention to official admission updates to avoid using outdated aggregate formulas.
10. Bayero University Kano (BUK)
BUK may combine UTME performance with other screening requirements during admission.
Candidates seeking admission into Medicine, Pharmacy, and Engineering should aim for high aggregate scores because competition is usually intense.
Example 1 of How to Calculate Aggregate Score for Nigerian Universities
Let’s assume:
JAMB = 300
Post-UTME = 74
Calculation:
JAMB:
300 ÷ 8 = 37.5
Post-UTME:
74 ÷ 2 = 37
Aggregate:
37.5 + 37 = 74.5
Example 2
JAMB = 245
Post-UTME = 82
Calculation:
245 ÷ 8 = 30.63
82 ÷ 2 = 41
Aggregate:
30.63 + 41 = 71.63
Although the JAMB score is lower, the excellent Post-UTME performance significantly boosts the aggregate.
Example 3
JAMB = 210
Post-UTME = 90
Calculation:
210 ÷ 8 = 26.25
90 ÷ 2 = 45
Aggregate:
26.25 + 45 = 71.25
This example shows why students should prepare seriously for Post-UTME.
Common Mistakes Students Make While Calculating Aggregate Scores
Many admission seekers calculate their aggregate incorrectly. Some common mistakes include:
1. Using Another University’s Formula
Each university has its own admission policy.
Never assume every institution uses the same calculation.
2. Ignoring O’Level Grades
Where O’Level is included, good grades can significantly improve your aggregate score.
3. Using the Wrong Subject Combination
Admission officers only consider relevant subjects.
Using unrelated subjects may produce an inaccurate aggregate.
4. Assuming JAMB Alone Determines Admission
A high UTME score does not automatically guarantee admission.
Your aggregate score is usually the deciding factor.
Factors That Affect Aggregate Score
Several factors influence your final aggregate.
1. JAMB Performance
A higher UTME score gives you a stronger starting point.
2. Post-UTME Performance
A strong Post-UTME score can compensate for a moderate JAMB score.
3. O’Level Grades
Excellent grades in your five relevant subjects improve your chances where applicable.
4. Competition
Highly competitive courses usually require higher aggregate scores.
Examples include:
- Medicine
- Pharmacy
- Law
- Nursing
- Medical Laboratory Science
- Computer Science
These programmes often have higher admission benchmarks than less competitive courses.
Ways to Improve Your Aggregate Score
If admission has not yet been concluded, you can still improve your chances.
1. Score High in JAMB
Aim for at least 250 or above if you’re targeting competitive courses.
2. Prepare Well for Post-UTME
Do not relax after writing UTME.
Many students lose admission because they underestimate Post-UTME.
3. Obtain Good O’Level Grades
Five credits are the minimum requirement, but distinctions can improve your aggregate in universities that consider O’Level performance.
4. Choose the Right Course
If your aggregate falls below the expected range for your preferred course, you may consider changing to a related course with lower competition.
5. Monitor Admission Updates
Universities sometimes adjust admission requirements or screening methods. Staying informed helps you avoid missing important deadlines or changes.
