With 442 as your Gate score in the open category, it is not going to be easy at NIELIT Aurangabad. Trying in lower ranked NITs is an option that you can consider and examples are Jharkhand, Jalandhar, Manipur, Agartala.  Have you registered under CCMT2020 for admission to their listed colleges and if you have any queries so you can write to: ccmt2020help@mnit.ac.in (mailto:ccmt2020help@mnit.ac.in)

If you happy with the 16 college’s list then was suggested, then rank them in order of preference and apply to the ones you like.  Do the necessary registration and necessary short listing to avoid any last minute uncertainties.

Good Luck!
