Nothing is valid abroad done in India.

While pursuing B.J. M. C. you'll learn Print, Electronic Media, PR, advertising, Radio and so on. If you're highly interested in PR course then choose a Diploma course in PR. I don't know about top college in Maharashtra but search in Pune for top colleges for B.J. M. C. or PR course.
