Can I do msc entomology after bsc microbiology
Offcourse Manisha, there is a big yes for you.A s long as you have studied microbolgy in your under graduate course, you're eligible for a MSc in entomology.
I would definitely try and figure out what you are looking to do long term and see if that Masters is worth the time and money.
hope you got your answer.
Good luck :)
