I would say try securing B.Tech in Biotechnology from VIT as your first preference, followed by B.Sc. in Biotechnology from Manipal University. Manipal and VIT are two of the best private institutions having strong faculty, infrastructure and research facilities. Incase you arent able to make into one of them try securing B.Tech in Biotechnology from SRMIST or B.Sc. in Biotech from Amritaa.
