How percentage to GPA conversion works
- • SSC/HSC uses a 5.0 scale with fixed grade bands (80–100% = A+/5.00, 70–79% = A/4.00, etc.).
- • National University uses a 4.0 scale with 10 bands (80–100% = A+/4.00, 75–79% = A/3.75, down to 0–39% = F/0.00).
- • For other universities on a 4.0 scale, a linear formula (percentage ÷ 100 × 4) is used — this is an approximation since no single standard exists across all institutions.
- • Results are estimated conversions, not official marks. Always verify with your institution.
