Which courses can I choose after B.Com except for CA, CS and ICWA?

You must be clear about your aspiring career, before setting an exception. After engineering, accountancy/finance is the most sought career. You can choose from professional courses like MBA, MCA, LLB and B.Ed, according to your interest. But the career rise will not be equal to CA/ICWA.

You can go for Masters in Journalism and Mass Communication, but you are not eligible for M.Sc in Fashion Designing. One year Diploma in Fashion Design may an alternative.

You can go for a Master's degree i.e, M.Com or move to MBA. You can always pursue mass communication if you can crack the entrance.
