For a general category student getting top NIT with cse branch at 150 marks is almost impossible until the god do some miracle so that you get higher percentile.

But 150 is a descent score!

You can try branches like ECE, EE, Chemical, Mechanical.

Dear applicant although your score is good but as you know to confirm a seat into Computer Science Engineering branch you need to score more than 195-200 for the NITs and IITs. But yes since 150 marks is also not bad you can expect seat into Institutions like NSUT, Delhi Technological University, few of the IIITs as well.
