Anna University R2021 grades
Under Regulation 2021, the calculator starts with these grade points:
| Grade | Grade points | Marks band |
|---|---|---|
| O | 10 | 91–100 |
| A+ | 9 | 81–90 |
| A | 8 | 71–80 |
| B+ | 7 | 61–70 |
| B | 6 | 56–60 |
| C | 5 | 50–55 |
| RA | 0 | below 50, re-appearance |
These are the fixed bands that apply when a course has 30 or fewer students. For larger classes the regulations allow relative grading, where bands depend on the class's marks, so always enter the letter printed on your result rather than working it out from marks.
Worked example
The sample loaded with the calculator:

| Data Structures | 3 | A+ (9) | 27 |
| Object Oriented Programming | 3 | B+ (7) | 21 |
| Digital Principles and Computer Organization | 4 | B (6) | 24 |
| Data Structures Laboratory | 2 | O (10) | 20 |
| Environmental Sciences | 2 | C (5) | 10 |
| Total | 18 | 134 |
GPA = 134 ÷ 18 = 7.44.
That is 74.44% using CGPA × 10. Over three semesters with 8.1 (24 credits), 7.6 (23) and 8.35 (22), the CGPA is 552.9 ÷ 69 = 8.01.
RA, W and classification
An RA grade means you must re-appear for the exam; it carries 0 points. Anna University calculates CGPA only from courses you have passed, so if you have an RA pending, remove that course from your GPA calculation to match the university's figure, then add it back with the new grade after you clear it. Withdrawal (W) and shortage of attendance are also left out. First class with distinction and first class are decided by CGPA together with rules on the number of attempts, so read the classification section of your regulations.
