Dear Devendhar, There is no specific stream that you should study your 10+2 to be eligible to study CA. CA has 3 phases like CA Foundation, CA Intermediate and CA Final. For being eligible for Foundation, you need to complete your 10+2 in any discipline and also complete a 4 month study plan. Now for the study plan, you need to join any coaching centre. But just to answer your question, even if you are studying MPC right now, you can study to become a CA.  For more information, please visit our page at: https://finance.careers360.com/articles/ca-cpt-eligibility-criteria
