Congratulations,you have scored very well
You can get NIT of your homestate, because there is homestate quota in wgich you can get admission in NIT by your rank I think you can get admission in CSE if you take admission in lower rank NIT.

• You can also take admission in some other Colleges which use jee mains rank to get admission.
• Take admission in THAPAR UNIVERSITY as you may get ECE or probably CSE in second or third round.
• You can also take admission in IPU if you are from Delhi it has some best Colleges like MSIT or MAIT.

If you only want NIT then you can get admission in NIT patna, Nit bhopal.
You can use the College predictor tool available on this website.
Good luck for your admissions.
