Indian Institute of Technology, Delhi

Hello my friend, your ranking in JEE Mains appears to be quite good but unfortunately this ranking is of no use for seeking admission in any IIT. For getting admission into IIT student needs to appear for and pass with good marks JEE advanced entrance examination. If you had appeared for this and got a good ranking then you have chances of getting admission in any of the IIT. For the branch of CSE, student needs to be in the top bracket of percentile then only has some chances.
Best wishes to you.

Hello Hritika, yes these two types of institutions have quite good name and ranking in the minds of students. But then there are other government colleges also in your own state or in some other states which also have good reputation academically as well as during placements. But gftis and iiit are definitely good institutions. Best wishes to you.
