hi soni,

The cost of B.Sc. in microbiology varies from college to college.

I will give you information about some colleges:

St. Xavier College, Mumbai - 34k for whole B.Sc. course

Madras Christian college - 71k for whole B.Sc. course

Jain university : 7 lakhs for whole B.Sc. course (too expensive)

Fergusson College,Pune : 36k for whole B.Sc. course

As you can see the B.sc course fees varies form college to college.

It can be 30k or can go upto 7 lakhs for total B.Sc. course

I hope this answer will help.
All the best for the future!!
