Hello student,

As you have said you are 75% visionary disable person, the according to the rule you come under PWD category.

JEE Main Reservation Criteria says that any students who are suffering from 40% or more disability (specified disability), as certified by the certifying authority can avail the benefit of PWD reservation.

Now on the basis of above analysis we can say that you will be eligible for PWD category reservation and for PWD category, cutoff of JEE Main is relatively low.

With 21 percentile you have high chance that you will be clearing JEE Main cutoff and hence we can say that you will be eligible for JEE Advanced too.

Lat year the cutoff for PWD category was 0.0618524 percentile.

I hope this information helps you.

All the very best!!
