How Anna University Assigns Grade Points
After every semester examination, Anna University converts your marks into letter grades. Each letter grade has a fixed grade point value ranging from 0 to 10.
These grade points are multiplied by the credit value of each subject to calculate your Semester GPA (SGPA). Your CGPA is then calculated using the weighted GPA across all completed semesters.
Because GPA depends on both grade points and subject credits, scoring an O Grade in a high-credit subject improves your CGPA more than scoring the same grade in a lower-credit subject.

| Grade Point | Numeric value (0–10) used to calculate GPA. |

How Grade Points Are Used to Calculate GPA
Anna University follows a credit-based grading system. Each subject carries a specific number of credits, and the final GPA depends on both the credits and the grade points earned.
The calculation is:
GPA = Σ (Credit × Grade Point) ÷ Σ Credits
For example, receiving an O Grade (10 points) in a 4-credit subject contributes 40 grade points, whereas an A Grade (8 points) contributes 32 points.
Students aiming for a higher CGPA should focus on improving grades in higher-credit subjects because they have a greater impact on the final result.
How Grade Points Affect Placements and Higher Studies
Many employers and universities evaluate candidates using CGPA rather than individual semester marks. Since CGPA is calculated from grade points, consistently earning O and A+ grades significantly improves your academic profile.
Students applying for postgraduate admissions, GATE, government recruitment or campus placements often need to convert CGPA into percentage using the official Anna University conversion formula.
