Hello lakshmi

The cutoff for all students are judged on the basis of ranks on AP EAMCET so i will attach a link for college predictor and a link where you check the cutoff of each branch of those colleges there so you can get an idea what will be the opening and closing rank of different colleges for Biotechnology
