How is CGPA calculated?
CGPA (Cumulative Grade Point Average) is a weighted average of all subject grade points. Subjects with more credit hours carry more weight in the final CGPA.
CGPA = Σ(Grade Points × Credit Hours) ÷ Σ(Credit Hours)
Example: Math (9, 4cr) + Physics (8, 3cr) = (36+24)/(4+3) = 8.57
Percentage = CGPA × 9.5 (standard Indian formula)
