Marks and GradesAnna University: CGPA to percentage and class
For B.E. and B.Tech. students of institutions affiliated to Anna University, Chennai. From the university's Regulations 2021 (Choice Based Credit System), in the amended copy on the Centre for Academic Courses website, read on 12 November 2026.
The formula
Clause 15.5.3 states that in the consolidated grade sheet the CGPA earned shall be converted into percentage of marks as follows:
percentage of marks = CGPA × 10
So a CGPA of 8.2 is 82%, and 7.45 is 74.5%. To go from a percentage to a CGPA, divide by 10.
Grade points
| Letter grade | Grade points |
|---|---|
| O (Outstanding) | 10 |
| A+ (Excellent) | 9 |
| A (Very good) | 8 |
| B+ (Good) | 7 |
| B (Average) | 6 |
| C (Satisfactory) | 5 |
| U (Reappearance) | 0 |
| SA (Shortage of attendance) | 0 |
| WD (Withdrawal) | 0 |
The regulations say a student is deemed to have passed a course, and earned its credits, on obtaining any of the grades O, A+, A, B+, B or C. U denotes that the student has failed to pass the course.
Classification of the degree
| Class | CGPA | Other main conditions |
|---|---|---|
| First Class with Distinction | Not less than 8.50 | All courses of all eight semesters passed in the first appearance, within five years. Different limits are given for lateral entry and the sandwich programme. |
| First Class | Not less than 6.50 | All courses of all eight semesters passed within five years. |
| Second Class | Below the above | All other students who qualify for the degree. |
Notice that the class depends on more than CGPA. A student with a CGPA of 8.7 who needed a second attempt at a course does not meet the first-appearance condition for Distinction. The regulations also say that an approved withdrawal from an examination is not counted as an appearance for this purpose.
Worked examples
CGPA 8.50, every course cleared at first appearance in four years. Percentage 85%. First Class with Distinction.
CGPA 7.20, one arrear cleared later, degree finished in four years. Percentage 72%. First Class.
What CGPA is 60%? 6.00.
Compared with other rules
Under Anna University's rule a CGPA of 8.2 is 82%. Under VTU's it would be 74.5%, and by the CBSE school formula 77.9%. Each is correct only for its own institution. See why there is no single formula.

- The clause on percentage was inserted by amendment; an older grade sheet may not carry a percentage.
- University departments and autonomous colleges of Anna University have their own regulations. Check which set applies to you.
- Regulations 2021 apply to students admitted under them. Earlier and later batches should read their own.
The converter has this rule as one of its choices.
