hello anmol

well there is nothing to do much in this case . after results you cannot change your category.you will be treated as a general category candidate .however there is not much difference in general and ews category ranking ,so you can get admissions if you got good jee mains ranking without using ews category

try checking colleges you can get using the college predictor
