| Your admission is determined by your aggregate score, not just your JAMB score. |
This is the question I get most right now: "I scored 248. Is it enough for Accounting?"
The honest answer is that your JAMB score alone means almost nothing. What decides your admission is your Aggregate Score, and every school calculates it differently. A score of 248 might be very strong for one university, borderline for another, and not competitive at all for a third.
In my years of guiding students through admission, I have seen brilliant candidates lose out because they didn't understand how their final score was calculated. Here, I break down every major system used in Nigeria, with real arithmetic examples you can compute with your own scores right now. (If you want to see the general cut-off marks for schools, read our JAMB Cut-Off Marks Guide here).
The Basic Principle
Your Aggregate Score is a weighted combination of:
Your JAMB UTME score (out of 400).
Your Post-UTME score (out of 100).
Your O'Level grades points.
JAMB itself has no standard formula. Every institution sets its own weightings, so you must know exactly how your target school calculates it.
The Most Common Grading Scale
Here is the O'Level grading scale used by almost all universities (out of a maximum of 20 points for 5 subjects):
A1: 4.0 points
B2: 3.6 points
B3: 3.2 points
C4: 2.8 points
C5: 2.4 points
C6: 2.0 points
D7, E8, F9: 0.0 points (Not accepted for core subjects).
Method 1: The 50:50 System (JAMB + Post-UTME)
Used by: UI, UNIBEN, UNN, and many federal universities.
This method ignores O'Level grades and focuses entirely on your JAMB and Post-UTME scores.
JAMB (50%): Divide your JAMB score by 8.
Post-UTME (50%): Divide your Post-UTME score by 2.
Total: 100.
Example:
You scored 260 in JAMB and 72 in Post-UTME.
JAMB: 260 ÷ 8 = 32.5
Post-UTME: 72 ÷ 2 = 36.0
Aggregate = 68.5 / 100
Method 2: The 50:30:20 or 40:40:20 System
Used by: UNILAG (50:30:20), OAU, and LASU (40:40:20).
This is the most comprehensive system because it includes your O'Level grades.
UNILAG Example (50:30:20):
You scored 270 in JAMB, 76 in Post-UTME, and you have 16 points from your O'Level (out of 20).
JAMB (50%): (270 ÷ 400) × 50 = 33.75
Post-UTME (30%): (76 ÷ 100) × 30 = 22.8
O'Level (20%): 16 points (assuming you have strong grades).
Aggregate: 33.75 + 22.8 + 16 = 72.55 / 100
Method 3: The 60:40 System (O'Level Heavy)
Used by: Most State Universities and Polytechnics.
Some schools use your JAMB score (60%) and your O'Level grades (40%). Many of these schools do not write a Post-UTME exam at all.
JAMB (60%): (Your JAMB score ÷ 400) × 60
O'Level (40%): Based on your 5 relevant subjects.
Method 4: The Point System
Used by: FUTO, FUTA, FUOYE.
In this system, your JAMB points and O'Level points are added together raw.
JAMB: Often divided by 8 (giving you a max of 50 points).
O'Level: Grades converted to points (e.g., A1 = 6 points, B2 = 5, etc.).
Aggregate: JAMB points + O'Level points.
A Major Myth Buster
Many students believe that dividing their JAMB score by 4 gives them a percentage. This is wrong. That was the old 2016 method. Today, dividing by 8 is the correct conversion for a 50-point scale.
What Aggregate Score Should You Target?
72+ / 100: Almost guaranteed merit admission.
65–71: Very safe, likely on the merit list.
58–64: Catchment area, ELDS, or supplementary list zone.
Below 55: Extremely difficult to secure admission.
Why This Matters So Much
When you know exactly how your school adds it up, you know exactly what to prepare for.
If O'Level is 20% and you have all A1s and B2s, you already have a huge head start before you even enter the Post-UTME hall.
If it is a 50:50 system, then Post-UTME is literally half of your entire chance, and you must prepare accordingly. (Read our guide on How to Check Your JAMB Result here).
