B.Sc Biology

You should concentrate on chemistry. Focus on this subject and you can work as a chemist in a laboratory.

B.Sc in Science or B.Sc in hotel management both courses have good scope and opportunities. So, don't bother about the scope choose the stream in which you are interested in. I can recommend you some colleges/universities offering both of these courses. Some of the universities are Lovely Professional University, BHU, BML, CNG etc.

B.Sc in biology has more scope.

Arun . you will have to appear for entrance exam conducted by cbse/ states and other colleges. and for this session it has already been done. you can try for BDS courses by private colleges

u can do MBA.

You can opt msc if u want to pursue higher studies in your own stream. Else you can pursue mba in pharma management or biotech management or forest management. It will be a good career enhancer for u. All the best. Thank you.
