All the best.

You need to pass out the class 12th then apply for UPSEE.

Since you have completed your schooling from a different state, you will have to submit a domicile certificate for WBJEE.

The basic eligibility for admission to MA in Mass Communication is a Bachelor degree in any stream of minimum 3 years duration. It is not compulsory to have a Bachelor degree in Journalism or Mass communication but it certainly gives an edge.
There is no restriction with respect to stream of education in graduation. However, certain universities do not accept application from students who belong to Engineering or Medical streams.

Yes, if you qualify JEE Advanced with good rank.
