How To Calculate JAMB Aggregate Score 2026
This is the question I get most right now: “I scored 248 — is it enough for Accounting?” The honest answer is: YOUR JAMB SCORE ALONE MEANS ALMOST NOTHING. What decides admission is YOUR AGGREGATE SCORE, and every school calculates it differently. One school 248 = very strong; another school 248 = borderline; another 248 = not competitive at all.
Here, I break down every major system used in Nigeria, with real arithmetic examples you can compute with your own scores right now.
BASIC PRINCIPLE
- JAMB UTME / 400
- Post‑UTME Screening / 100
- O-Level Grades points
| Grade | Points |
|---|---|
| A1 | 6 |
| B2 | 5 |
| B3 | 4 |
| C4 | 3 |
| C5 | 2 |
| C6 | 1 |
| D7–F9 | 0 |
METHOD 1 — 50:50 JAMB + POST‑UTME (NO O’LEVEL)
Used by: UI, UNIBEN, UNN, and many federal universities
AGGREGATE = (JAMB ÷ 8) + (POST‑UTME ÷ 2)
- JAMB / 400 → / 8 = out of 50
- Post / 100 → / 2 = out of 50
- TOTAL = 100
METHOD 2 — 50:30:20 / 40:40:20
Example UNILAG: J 270 = 33.75 | P 76 = 22.8 | O’Level = 24/30 → 16 → TOTAL = 72.55
METHOD 3 — O’LEVEL HEAVY 60:40
JAMB 60 % + O’Level 40 %, many write NO exam at all
METHOD 4 — POINTS SYSTEM
JAMB pts + O’Level pts added raw
❌ MYTH BUSTER
“JAMB ÷ 4 = %” ❌ WRONG, that is the old 2016 method. ÷ 8 is the correct conversion today.
WHAT SCORE SHOULD YOU TARGET?
- 72 + / 100: Almost guaranteed merit
- 65–71: Very safe, on merit list
- 58–64: Catchment / Elds / supplementary zone
- < 55: Extremely difficult
WHY THIS MATTERS SO MUCH
