Hi

Bsc biotechnology from dg vaishnav would be a little better option.

First of all the ranking of this college is pretty good it ranks 96 by NIRF.

Also the infrastructure, quality of teaching, faculty, campus lifestyle is amazing.  Bsc biotechnology also requires lot of practical knowledge so its very important that lab facilities are also good and there the practical labs are pretty good and also they are getting more advanced.

Crescent university although is not bad one can always keep this option open.
