Hii Avinash 

LNMIIT Jaipur is one of the prestigious college of Rajasthan which have its own standard. The LNMIIT is running by Mr. Lakshmi Naryan Mittal.

Getting into LNMIIT is not tough but not so easy as well. The student must score above 140+ inorder to occupy the seat. But student's also remember one thing LNMIIT doesn't have all the branches. It has only few branches. So accordingly student have to select.

So as you are expecting 91 marks in your JEE paper. I think it will be tough for you to get in LNMIIT. But don't loose hope many other good colleges are there where you can easily get admission. 

All the best.
