Gaining admission into Lagos State University is highly competitive. Every year, thousands of aspirants flood the admission portal, but only a fraction secure a spot. When your JAMB and O'Level results are finally released, it is completely normal to feel a mix of excitement and deep anxiety about where you stand.
Many students make the costly mistake of simply comparing their raw JAMB scores with their peers or relying on outdated cut-off marks to gauge their chances. The reality is that LASU uses a very specific, weighted formula to grade candidates, and they even penalize candidates who combine multiple O'Level sittings. If you don't calculate your exact aggregate, you are flying blind, which could cost you the window of opportunity to switch to a less competitive course.

If you prefer to see exactly how the university arrives at your final score, here is the complete breakdown of the LASU grading system.
How the LASU Formula Works
LASU grades aspirants over a total of 100%. The formula evaluates three elements: your JAMB score, your O'Level grades, and the number of exam sittings you used to acquire those grades.
Here is the step-by-step mechanics of the calculation.
Step 1: Your JAMB Score (Maximum 60 Points)
Your UTME performance forms the foundation of your aggregate, holding a massive 60% of the total weight. To convert your JAMB score into LASU's point system, a specific multiplier is applied.
The Formula: Simply multiply your total JAMB score by 0.15. (For example, if a candidate scored 300 in JAMB: 300 × 0.15 = 45 points).
Step 2: Your O'Level Subjects (Maximum 40 Points)
Your O'Level results (WAEC, NECO, or NABTEB) make up the remaining 40%. You only need to select the 5 core subjects strictly required for your proposed course of study.
LASU assigns a specific numerical value to each grade. You add up the points for your 5 relevant subjects based on this scale:
- A1 equals 8 points
- B2 equals 7 points
- B3 equals 6 points
- C4 equals 5 points
- C5 equals 4 points
- C6 equals 3 points
(For example, if you scored straight A1s in your 5 core subjects: 5 subjects × 8 points = 40 points).
Step 3: The Sittings Penalty
This is where LASU differs from many other universities. They actively penalize candidates who do not clear their papers in a single sitting.
- One Sitting: If all 5 of your required subjects were passed in a single exam session, you get 0 penalty (your score remains untouched).
- Two Sittings: If you combine two different results (e.g., WAEC and NECO) to make up your 5 subjects, LASU deducts a flat 1.5 points from your final aggregate score.
Putting It All Together: A Sample Calculation
Let’s calculate the aggregate score for a fictional aspirant named Chinedu, who is applying to study Economics.
Chinedu's Academic Profile:
- JAMB Score: 240
- O'Level Grades (2 Sittings): Mathematics (A1), English Language (B3), Economics (A1), Commerce (B2), and Financial Accounting (C4).
The Calculation
1. Calculate the JAMB Points:
- Chinedu's JAMB score (240) multiplied by 0.15.
- 240 × 0.15 = 36 Points
2. Calculate the O'Level Points:
- Mathematics (A1) = 8 points
- English Language (B3) = 6 points
- Economics (A1) = 8 points
- Commerce (B2) = 7 points
- Financial Accounting (C4) = 5 points
- Total O'Level Points = 8 + 6 + 8 + 7 + 5 = 34 Points
3. Apply the Sittings Penalty:
- Since Chinedu combined two results to get these grades, he receives a 1.5 point deduction.
- Penalty = -1.5 Points
Final Aggregate Score:
- JAMB Points (36) + O'Level Points (34) - Sittings Penalty (1.5)
- 36 + 34 = 70
- 70 - 1.5 = 68.5%
Chinedu's final admission aggregate score for LASU is 68.5%. He can now compare this score against the official departmental cut-off mark for Economics to determine his chances.
