Hello Praveen

Here is the eligibility criteria that you need to qualify for CA.

A candidate becomes eligible to register for CA only after passing(10+2) examination conducted by an examining body constituted by law or a recognized board.

To become CA first you need to qualify CPT (Common Proficiency Test) or CA Foundation (introduced by ICAI as per the new scheme) examination conducted by ICAI. After that there are further levels of exams that you need to qualify for CA.

Best of luck
