Under Anna University Regulations (R2021), letter grades map to the following points: O (Outstanding) = 10, A+ (Excellent) = 9, A (Very Good) = 8, B+ (Good) = 7, B (Average) = 6, C (Satisfactory) = 5, and RA (Re-appearance/Arrear) = 0.
R2021 Regulation Grade Mapping
This is the official grading structure applicable to students registered under the R2021 regulation syllabus. Detailed syllabus maps are available on the Anna University Portal:
| Letter Grade | Meaning | Grade Points |
|---|---|---|
| O | Outstanding | 10 |
| A+ | Excellent | 9 |
| A | Very Good | 8 |
| B+ | Good | 7 |
| B | Average | 6 |
| C | Satisfactory | 5 |
| RA | Re-appearance (Arrear) | 0 |
Comparison: R2017 vs R2021 Regulations
In the older R2017 regulation, the lowest passing grade point was 6 (Grade U / average), whereas the R2021 regulation introduces Grade C (5 points) as the satisfactory threshold. This means students under R2021 have a slightly lower minimum point threshold to pass, though overall GPA weighting dynamics remain credit-balanced.
