Yes, you are eligible for CAT Exam.
The qualification criterion that is needed for a student to apply for the Common Admission Test is a graduate degree from an approved college. The students can be from any stream, but they are required to have a score of at least 50 percent in their final exams. Students of the SC/ST/PH and OBC communities require only 45 percentage marks. Those who are writing their final year exam are qualified to appear for the exam too. Approach a good institute like TIME as it is very hard to prepare all by yourself.

Hello Shivam,
CAT takes exam only in English, you must need to score 50% marks in your graduation after that you are eligible. All the best.

Class 10th or Class 12th marks don't matter for applying CAT or MAT. All you are required to have at least 50% in graduation, and if you are in final year, then you must have maintained at least 50% marks in the last 2 year's exam.
