Hi there.

Yes, you can take admission in bsc microbiology without giving any entrance exams whatsoever. But you need to keep certain things in mind. If you want to do bsc in microbiology from any of the reputed institutions across the country, then you need to score a good percentage in a 12th board examination because some colleges admit students on the basis of their 12th board result while some other institutes carry out their own entrance examinations.

Here I am providing you with a link which might help you to know the course better.
