Hi,
Yes, you can go for MA (Journalism & Mass Communication) after BCA. Eligibility criteria for MA (Journalism & Mass Communication) in most of the top universities is a pass with 50% aggregate marks in Bachelor's degree. (It may vary with the university you choose)
The most important thing is that from where you pursue your post graduation. Its better to choose good institute or university which offers you good practical and industrial exposure, good placements like:
Lovely Professional University- Punjab, Sri Ram College of Commerce (SRCC) - Delhi, Department of Commerce - Christ University - Bangalore, Lady Shriram College for Women (LSR) - Delhi, Hansraj College - Delhi, Loyola College - Chennai, Christ university and few others. These universities also offer various skill development programmes, professional enhancement training and outstanding exposure to its students. They also provide worthy scholarships to its students depending upon the entrance test taken of the university or board result. These universities also offers top class learning environment to the students with extensive placement opportunities. I hope it helps.
