I don't understand what 'valid by the government' is. NIFT has a diploma program in fashion design and a 6 month certificate course. It hard to say how much you'll earn and how 'practical' it is. You can make uuseful contacts during your time at NIFT and that will help you in earn I guess.

The last admitted rank in NIFT-Patna in 2018 was 567 CMR. I'd say settle for any seat you get and apply till the last round of counselling as your chances are low. You can always work harder in your first year and then transfer to another college provided they have a seat available.

Being an SC candidate, you need atleast 65% aggregate marks. It is 75% for general candidate.

Form is being filled. It is online process then entrance exam will be there in the department. There are 100 seats.

For BA entrance test, questions will be related to GK and humanities and social sciences.

BJMC is generally offered in both Hindi and English. Even MJMC has been offered in Hindi as well. I wish you find it out from the concerned university Prospectus or Inquiry department. In my view, I shall say that one should prefer English as a medium so that Mass Comm Degree gets proper value.
