Career

There is the whole sky open and no boundary or limit. Instead of doing regular BA in any subject. Choose a specialisation subject where you can enhance and shape your further studies or career. Like Doing BA English (Hons), or BA Psyshology, BA Jounalism & mass communication and so on.
Think your area of interest and choose right subject.

Important Advice- 11th has Media and Mass Communication Optionals now. Take those. Do Bachelor's degree in Mass Communication and Journalism. We call them BJMC, BMM, B.Sc Mass Communication, etc. and not B.Com. I don't understand why B.Com was suggested. 12th through Arts and Media options will prepare you.
After Bachelor degree in Mass Communication, do Post Graduation in Mass Communication.
