B.Sc

Hello,
https://www.shiksha.com/mba/articles/top-5-mba-specializations-in-india-blogId-3223 Visiting the given link would help you get some valuable information about the MBA specialization you would wish to pursue.

As for my perspective, you should go for B.Sc or B.Tech in private college, because your class 12th percentage are not good.

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.

The Eligibility for pursuing a Bachelor of Science Degree in Information Technology is a pass in HSC (with Mathematics as a paper). Even without Science Group you can apply in many colleges, but not without Maths in HSC.

You have passed B.Sc (with Chemistry, Botany & Zoology), so it is a Graduate Degree programme in Life Sciences, which is eligible to apply for the Admission in the M.Sc (Diabetes & food nutrition).

There is no Entrance Exams for a B.Sc (Microbiology) - Three Years Duration Course. But, colleges will conduct Merit Based Admission and depends upon the Ranking from Applications you will have the scope.
