Hi Piyush,

Your WBJEE rank is enough to get admission in IEM Kolkata or Heritage Institute of Technology (HIT), Kolkata.

But, as far as I know, you need an overall aggregate of 60% in 12th Boards for the GENERAL category candidates to be eligible for B.Tech in IEM Kolkata.

To get admission in HIT, you need an aggregate of 45% in Physics, Chemistry and Mathematics combined.

Hope this helps you.

All the best!!!
