As your Bcom is completed you can opt for conversion into direct entry scheme for giving your CA Intermediate | CA IPCC attempt in Nov 2017.
Following are the requirements-
1. complete orientation programme.
2. complete ITT training.
*for conversion process you will need a DD of 500rs.
3. complete 9 months of articleship.
you will first have to complete both OP and ITT before or upto Dec'2016 so that you can join a firm for articleship and 9 months will get completed on sept'2017.
Yes, you can start your articleship on the basis of direct entry scheme as you have completed your graduation and you will be able to appear for CA Intermediate | CA IPCC exam only if you complete the above requirements.
PS : you still have enough time, join a firm which is lenient and flexible, focus more on clearing CA Intermediate | CA IPCC rather than articleship.
All the best (:
