The Nigeria Grading System Explained
Nigeria uses a 5-point scale: First Class (70%+/4.5-5.0 GPA), 2:1 (60-69%), 2:2 (50-59%), Third (45-49%), Pass (40-44%).
Nigerian university finals are typically worth 60-70% of the course grade, with continuous assessment accounting for 30-40%.
Quick Example (35% final): 80% current → Need >100% for top grade | Need 80.0% for merit/good grade.

How to Use This Calculator for Nigeria 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)
