Diploma

Hi Abhishek!
Mass communication opens up several avenues for you to chose your career path. You can chose to work in a news organisation as writer, reporter, editor, photojournalist etc. You can work for an advertising or PR firm. You can also work for a radio or TV channel for various designations depending on your area or interest. You also have an option of becoming a Media Faculty or Media Researcher. The opportunities are limitless for a Mass Communication person. All you need is to figure out where your interest lies and then approach for organisations working for that particular industry.

No, if you want to do B.Com then you would have to complete 12 with commerce.

No scholarship. Even, you have to pay a hefty fee and you can't go for a job in this duration. The best option for you is doing AMIE. It is the best and the only option for Diploma pass students.
