Suggestions to those studying Microbiology from Apurba Sastry Microbiology PDF in the Second Year MBBS are as follows:

  1. Stay active in lectures and classes. Jot down essential points your professors teach you. Use them wisely days before the exam.

  3. Have a better grasp of finds on microscopy. Practicals are relatively difficult and many mug them up. In real scenarios, it becomes disastrous to understand any single of them.
