The Singapore Grading System Explained
NUS, NTU, SMU use CAP (5.0 scale): A=4.0 (85%+), B+=3.5, B=3.0 (75%+), C+=2.5, C=2.0 (65%+), D+=1.5, D=1.0 (55%+), F=below 55%.
Singapore's top universities often use bell-curve grading — your class rank matters as much as your raw score.
Quick Example (35% final): 80% current → Need >100% for top grade | Need 80.0% for merit/good grade.

How to Use This Calculator for Singapore Courses
The formula works identically regardless of grading scale — what changes is the label on the target. Use these conversions:
- First Class / Distinction / A = target 70-90% depending on your institution's cutoff
- Merit / 2:1 / B = target 60-70%
- Pass / 2:2 / C = target 50-60%
- Minimum pass = target 40-50% (check your institution's exact threshold)
