Colleges in Delhi

For FMS, Delhi you need 99.6 percentile atleast and average for general category is 99.7 percentile.

The fee structure is 1.3 lakhs per year for MJMC.

It's definitely a good university for a professional course like BBA, but as long as you know how to make the best out of the three years in a university which doesn't really have a lot of good clubs of its own but provides you with ample amount of time and resources to be part of things outside.

Hi Mohit, you need to have atleast 50% in 12th to secure admission in Amity.

As you are in 12th, all you need is to maintain 75% or more than 75% in CBSE boards exam and need to clear JEE Mains exam with a good score. Just qualifying JEE Mains with the minimum cutoff doesn't make a sense. If you want mechanical with specialization in automobile you need atleast 180+ in Mains.
So don't worry, just focus on your boards and JEE Mains preparation.
All the best!!
