You haven't mentioned your subjects in your 12th. Neverthless, CBSE has released a list of 113 courses that a student can pursue after 12th in each stream. Few courses like CA, CS, LLB, do not have specific subjects to be studied. But few courses like MBBS, B.Tech have few subjects listed as mandatory. Without knowing your 12th core subjects, it is difficult to make a list for you. You can check the complete list at: http://cbse.nic.in/newsite/attach/Compendium%20of%20Courses%20after%20+2.pdf
