IIFT-Delhi is a better option over IIFT-Kolkata because of the academic environment, faculty and better placement record. It is the mother B-School for IIFT-Kolkata. IIFT has a wider alumni network which will help in getting better summer and job placement and also growth after MBA.

The best institute to take admission is Satyajit Ray Film & Television Institute.

I hope, this will help you.

Dear Suman,
Not just in India, but in the entire world, you can never do engineering and medical through distance mode. So don't ask for B.Tech college in distance mode in Kolkata as you will not find and even if any college offers B.Tech in correspondence, means they are violating the rules of AICTE. Go and complaint them. So, go for regular B.Tech program.
Ask any query at anytime.
Good day.
