Mass Communication & Media

Hi Vikas,
See, Diploma in journalism, first of all, in AMU is on-campus that means no distance learning is offered.
Secondly, if you want to make a career in journalism and print media then a post-graduate degree in journalism is required.
Talking about the qualities, one should have a curious mind, will power, an aptitude for presenting information in a precise, concise and effective manner. It's well and good that you have decided your goals, just set out the path and travel on those and there are many people who will guide you to help you reach your goals.
Best of luck.

Mass communication and journalism is a really vast field and you will have to specify this thing in your mind that what you want to go for journalism or mass media. There are a lot of different course related to Mass communication. I'm from Lucknow and I won't suggest you to go for any media college in Lucknow. If you are really passionate about the field then atleast go for Amity-Noida but I would recommend you apply for colleges like St. Xavier's-Mumbai, Christ College-Bangalore, Manipal University-Karnataka campus or Jaipur.

Amity is the best option among the colleges you have mentioned but it also depends on what you want to go do, journalism in specific or mass media.

Maths is not compulsory for BMM. You can opt for BMM after completing 10+2 in any stream.

The list is huge and you'll have to decide which specific field of communication and journalism you want to go for. If you want to go for journalism then you can consider colleges like:-
St. Javier's, Mumbai
Christ College, Bangalore
IIMC, Delhi
SIMC, Pune
Manipal University, Karnataka
MICA, Ahmedabad
I would suggest you tell the specific field of media and communication you want to study because it matters a lot that which field of the media industry you are planning for.
