*Yabatech Aggregate score grading system 2026*
*YABATECH Screening Aggregate Calculation Guide*
For those asking how YABATECH calculates its screening aggregate, here's the breakdown:
1. JAMB Score (60 Marks)
Your JAMB score is converted from 400 to 60 using this formula:
(Your JAMB Score ÷ 400) × 60
Example:
If you scored 280 in JAMB:
*(280 ÷ 400) × 60 = 42 marks*
1. O'Level Result (30 Marks)
Your five relevant O'Level subjects are graded as follows:
Grade key
- A1 = 6 points
- B2 = 5 points
- B3 = 4.5 points
- C4 = 4 points
- C5 = 3.5 points
- C6 = 3 points
*Add the points for your five relevant subjects*
1. Number of Sittings (10 Marks)
- One sitting = 10 marks
- Two sittings = 5 marks
Final Aggregate Formula
*Aggregate = JAMB (60) + O'Level (30) + Number of Sittings (10)*
Example:
- JAMB: 280 = 42 marks
- O'Level: A1, B2, B3, C4, C5 = 23 marks
- One sitting = 10 marks
Total Aggregate = 42 + 23 + 10 = 75%
Jamb score 60%
Number of sitting 10%
Olevel result 30%
Total 100%
