Both courses teach the similar papers. The only difference is that you can specialize in a certain subjects in B.Com (H), but the B.Com (P) course gives an overview of all those subjects taught in the honours course. B.Com can be a stepping stone for further professional degrees like Chartered Accountant (CA), Company Secretary (CS) and Cost and Work Accountancy (ICWA), Cost Accounts, CFP, Chartered Financial Analyst Program (CFA), Actuarial science etc. For getting admission to these courses you have to appear for the entrance examination conducted by the respective institutes.
