Suggestions to those studying physiology from AK Jain Physiology PDF in First Year MBBS are as follows:

  1. Try to stick to one book, multiple books will just confuse you. Pick one and read it with heart since physiology is going with you for the rest of your medical career.
  2. You can watch some YouTube videos since there are many, to clear the concepts of some mechanisms. You don’t want to miss out on some fundamental essential topics without understanding them, do you?
  3. Yes A.K. Jain is the recommended book in most colleges, but no one is forcing you to read it. Well, it is still the simplest book I have ever seen, but if you need K Sembulingam or Guyton, you can always check them out too.
