Marks to GPA Conversion Scale
Step 1: Percentage = (Marks ÷ Max Marks) × 100
Step 2: Map percentage to GPA using standard US scale
93–100% = 4.0 (A) | 90–92% = 3.7 (A-) | 87–89% = 3.3 (B+) | 83–86% = 3.0 (B)
80–82% = 2.7 (B-) | 77–79% = 2.3 (C+) | 73–76% = 2.0 (C) | 70–72% = 1.7 (C-)
Step 2: Map percentage to GPA using standard US scale
