How GPA to percentage conversion works
- • SSC/HSC uses a 5.0 scale with fixed grade bands (A+ = 80–100%, A = 70–79%, etc.). The result is the midpoint of the matching band.
- • National University uses a 4.0 scale with 10 bands (A+ = 80–100%, A = 75–79%, down to F = 0–39%).
- • For other universities on a 4.0 scale, a linear formula (GPA ÷ 4 × 100) is used — this is an approximation since no single standard exists.
- • Results are estimated ranges, not exact marks. Always verify with your official transcript.
