ℹ️ CGPA = Σ(SGPA × semester credits) ÷ Σ(credits). Credits matter — a 4-credit core subject moves your CGPA twice as much as a 2-credit elective.
⚠️ The two percentage conversions disagree on purpose: ×9.5 is the CBSE rule and (CGPA − 0.75) × 10 is used by many universities. Use the conversion YOUR institution publishes on any official form.
