Hi Jaya!
You can pursue B.Sc in catering from this college but you have to start with B.Sc in catering from the 1st year itself.

Yes. You can do M.Sc. Microbiology after B.Sc. Zoology, all you need is 60% aggregate in B.Sc. But it will difficult for you because you won't know the basics of microbiology, so you will have to work hard for M.Sc. Microbiology.

There's not much difference between the two. But the only main difference I can point out is that. One is for 3 years and another for 4 years. Both the courses gets similar placements . or jobs . But another difference is that government IHMs offer only BSc and not BHMCT

English subject marks are counted but if I ask specifically about PCM, then it is not added, else it will be added.
