Hello Priyanka,

Since you did not mention the stream it is hard to tell but I suggest you go through the following link where you can check below the GATE cutoff for previous years' PSU recruitment:

Frankly, getting a seat in IIT depends upon ranking and cutoff for the session instead of marks, higher the difficulty level of paper-lesser the marks required to make a good ranking. You can also check the GATE cut off for various IITs depending upon your stream and category from the following link so that you can get a rough idea -

Hope this helps.
