Tools for students
Convert marks to a percentage, a percentage to CGPA using your board’s factor, or calculate a credit-weighted GPA. The Attendance Calculator shows how many classes you can miss or must attend to stay above 75%, and the Final Exam Grade Calculator tells you the score you need for your target.
Universities publish their own conversion rules, so always check your institution’s official method before using a converted figure on an application.
Quick tips
- CBSE uses CGPA × 9.5 to estimate percentage; many universities use other factors.
