Dear candidate 

Yes you can if you are passionate about it.For CA, you first need to give the foundation exam which is called common proficiency test (CPT) conducted by ICAI. You can join coaching centres for preparations or can do it yourself at home.

You can entrol yourself with ICAI for intermediate course after your graduation.

As per ICAI, commerce graduates with 55%marks and other graduates with 60% marks can enroll themselves directly for intermediate course. If you haven't scored the required marks you will have to appear for CA foundation first. 

However you have to be very passionate about CA because you will have to learn everything from the beginning and have to work really hard to clear your basics.

Hope the answer is helpful.

All the best.
