How Universities Calculate Screening and Aggregate Scores (2025 Updated Guide)

Gaining admission into Nigerian universities is highly competitive, and understanding how institutions calculate screening scores and aggregate scores can significantly improve your chances of gaining admission. Every year, thousands of candidates miss out on admission simply because they do not understand how their scores are computed—especially in universities that use complex formulas.

This guide explains, in clear detail, how Nigerian universities calculate aggregate scores, the differences in screening systems, and the official links where you can verify each school’s method.

1. What Is an Aggregate Score?

An aggregate score is the final score a university uses to determine whether a candidate qualifies for admission. It is usually calculated using a combination of:

• JAMB (UTME) score
• Post-UTME score
• O’level grades (for some schools)
• School-specific weighting formulas

Each university chooses its own system and formula, which is why understanding your school’s method is extremely important.

You can always check admission guidelines from the school’s official website or JAMB’s official portal:

2. Different Types of Screening Used by Universities

Universities in Nigeria use one of the following methods:

A. Post-UTME CBT Examination + JAMB Score

This is the traditional method used by many universities such as:

• University of Lagos (UNILAG) – https://unilag.edu.ng
• University of Benin (UNIBEN) – https://uniben.edu
• University of Port Harcourt (UNIPORT) – https://uniport.edu.ng
• University of Ibadan (UI) – https://ui.edu.ng

B. JAMB Score + O’level Screening (No Post-UTME Exam)

Some universities do not write Post-UTME. They calculate screening scores using the candidate’s JAMB score and O’level grades. Examples:

• University of Ilorin (UNILORIN) – https://unilorin.edu.ng
• Lagos State University (LASU) – https://lasu.edu.ng
• Osun State University (UNIOSUN) – https://uniosun.edu.ng

C. Online Screening Only

Some schools use document uploads and automated scoring instead of physical exams.

3. How Major Nigerian Universities Calculate Aggregate Scores

Below are verified calculation methods used by popular universities.

A. UNILAG Aggregate Score Calculation

UNILAG uses:

• JAMB Score (50%)
• Post-UTME Score (30%)
• O’level Grades (20%)

Formula:
Aggregate Score = (JAMB/8) + Post-UTME + O’level Score

Example:

• Candidate JAMB Score = 280
• Post-UTME Score = 25
• O’level Score = 12

Aggregate = 280/8 + 25 + 12 = 72.0%

🔗 https://unilag.edu.ng

B. University of Benin (UNIBEN) Aggregate Score

UNIBEN uses a simple method:

• JAMB Score (50%)
• Post-UTME Score (50%)

Formula:
Aggregate = (JAMB/8) + (Post-UTME/2)

Example:
JAMB 300 → 37.5
Post-UTME 60 → 30
Total = 67.5%

C. University of Ibadan (UI) Aggregate Score

UI uses only JAMB and O’level grades (no Post-UTME exam since 2021):

Formula:

• JAMB Score = 50%
• O’level Grades = 50%

Example:
JAMB = 300 → 300/8 = 37.5
O’level (AAAAB) could give around 38 points

Aggregate = 75.5%

D. Lagos State University (LASU) Screening Formula

LASU uses:

• JAMB Score (50%)
• O’level Grades (50%)

Candidate O’level grades are converted as follows:

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

The top five required subjects are used.

E. UNILORIN Aggregate Score Calculation

UNILORIN does not conduct Post-UTME.
They use:

• JAMB Score (50%)
• O’level Result (50%)

O’level is graded similarly to LASU.

F. OAU (Obafemi Awolowo University) Aggregate Score

OAU uses a combination of:

• JAMB Score (50%)
• Post-UTME Score (50%)

Formula:
Aggregate = (JAMB/8) + (Post-UTME/2)

Example:
JAMB = 280 → 35
Post-UTME = 50/2 = 25

Total = 60.0%

G. UNIPORT Aggregate Score Formula

UNIPORT uses:

• Screening Test/Interview Score
• JAMB Score

Often weighted 60:40 or 50:50 depending on the department.

4. How O’level Grades Are Converted to Points

Most universities follow a similar grading system:

Grade	Points
A1	10
B2	9
B3	8
C4	7
C5	6
C6	5

Some universities use only relevant five subjects based on the candidate’s course.

5. Why Aggregate Scores Matter So Much

Understanding your aggregate score helps you:

• Predict your admission chances
• Choose the right course during JAMB change of course
• Know whether to switch to a less competitive department
• Prepare better for the Post-UTME
• Avoid last-minute surprises during admission

6. Where to Confirm Your School’s Calculation Method

Always rely on official sources:

A. JAMB Official Portal

🔗 https://www.jamb.gov.ng

B. School Websites (examples):

• UNILAG – https://unilag.edu.ng
• LASU – https://lasu.edu.ng
• UI – https://ui.edu.ng
• OAU – https://oauife.edu.ng
• UNIBEN – https://uniben.edu

Avoid unverified blogs or social media posts.

Understanding how your university calculates aggregate scores is one of the most important steps in securing admission. Every university uses a unique formula—some consider only JAMB scores, some combine JAMB and Post-UTME, while others include O’level grades.

To avoid mistakes that could cost you admission, always:

• Check your school’s official website
• Know the exact formula used
• Monitor your aggregate score early
• Use official JAMB resources

With accurate knowledge and proper planning, you can calculate your chances correctly and position yourself for successful admission.
