Exact, not rounded
Thresholds are compared on exact values. 74.99% is never shown as a pass. Every formula is covered by automated tests, including the edge cases.
Honest about formulas
CGPA-to-percentage rules differ by university. We label each formula with how well it is sourced instead of pretending one multiplier fits everyone.
