Hey!There

This year total score of JEE MAINS paper 1 has been changed by NTA.JEE MAIN PAPER1 will be of 300 marks.Seeing previous year trends of JEE MAIN, 20+ marks in PWD category can give you seat in NITs.

I hope this helps..

Hello there

I dont think 40 marks in JEE Mains would fetch you a seat in NITs. Try atleast for 90 marks.And to be honest its not that hard to score 90 marks in JEE Mains.Just attempt the questions you know for sure to reduce negative marking.Concentrate on chapters that you are thorough in.With a little bit of preparation you can easily get a seat in NIT.You can get a better idea by looking at previous years cut offs.
