Hello Ashu

as far as your JEE marks is concerned then you are quite well off but as far as your percentage is concerned then its quite backlagging.

See, first of all you dont qualify the basic eligibility criteria for JEE mains that is 75% but please do check form your board whether you are in top 20 percentile in your board.

If its so then you will get NITs, BIT mesra and other GFTIs also.

But if you dont qualify the above criteria then you cannot get into NIT.

in that case i would suggest you to go for GFTIs or you can also opt CSE in PEC and Thapar.

Hope that helps!
