What I would suggest you is that, first complete your Graduation in B.Com. Try getting a Part Time/Full Time Job or maybe enroll in M.Com and parallely prepare for CA. This will not only help you getting experience and knowledge but also a strong preparation for CA Exam. Another way might be parallely completing B.Com and preparing for CA Exam.
