Hello dear,

The cutoff of PWD GENERAL students for JEE mains is close to 20 . , if you get more than that like 35 marks you will be able to get NIT's . f you go anywhere greater than 50 you can easily get an IIT .This is the best opportunity to get seat in top institutes with least marks .

Good luck !
