CGPA Basics in 60 Seconds

Weighted, not simple

CGPA is weighted by credit hours, so higher-credit courses matter more.

Scales vary

A 3.5 on a 4.0 scale is not the same as 8.5 on a 10.0 scale without conversion.

Formulas differ

Percentage conversion uses institution-specific formulas; always verify your policy.

Planning helps

Target planning shows what average you need in remaining credits to reach your goal.
