Method 2
This second method is not that common as it is some schools that use it. In Nigeria, some universities calculate their aggregate score to be over 100:

- Also, you Post UTME is 80.
- Sum both your JAMB and Post UTME score together after division.
Step 1:
(300 ÷ 400) × 50 = 37.5.
Step 2:
(80 ÷ 100) × 50 = 40.
Step 3:
Aggregate = 37.5 + 40 = 77.5.
This mean that your finally aggregate score is 77.5.
