Hello Harshit.

There is only one way to get admission into NITs . If you are interested in NIT Delhi BTech computer engineering then keep in mind that it is among the top rank NITs of India. For this you have to score much more than the cut off marks of JEE mains. This year exam pattern and all things also changed very much. It will be much better for you to target at least 180 marks.

Hope you get it.

Good luck
