Hey Sushant,
Most of the top business schools don't offer direct admission or they have some predefined criteria. You can check out the following colleges which have some such criteria as well as best placement statistics.

If you want to join a really good college, your target should be at least 95 percentile. Joining a good MBA college is the first step towards a great career and life ahead. Faculty, placements and alumni committee play important roles in deciding what steps should be taken for a great career.
Career

Hey Devanshi,
I suppose this question can't be answered too simply. You can go abroad if you are getting a chance and you should. But then thinking financially India also has some best institutions standing with international standards. You can pursue your higher degree here only and go for education

You didn't mentioned your background. And of course MBA is a good decision.

If you have any reservation, then there could be a possibility in lower NITs otherwise no chance. I will suggest you to apply in other colleges like UPES Dehradun, ITM Gwalior, JIIT Noida, Thapar, NSIT etc to have a backup as competition is very difficult to get a seat for top engineering branches i
