Biotechnology

Reva University is an upcoming university with new records every year with placement and it's good for M.Sc.

Actually, going for MBA after Science or Technological background makes more sense if you take specializations like Data Science, Operations, and Business Analytics. As research work in Bio-Tech is taking big strides I guess analytics along with Bio-Tech will be a good mix. Many firms in pharmaceuticals and food-processing industry need quality analysts. So, if you get opportunity to get Data Science/ Business Analytics course, then its a hood option.

Yes, you're eligible. You shall go and visit various websites and check their notices and criterion.

If it's B.Tech in biotechnology, the fee in private colleges would be in Lacs and if it's B.Sc in Biotechnology, it would be from 40K up to 80K in most of the colleges.
