First of all congratulations to the people you have gone through one of the toughest exams of our country

• Anatomy- The biggest fear of any MBBS 1st year student. A boy who had just cleared the NEET by reading NCERT text books for him it seems that he will not be able to cover this deadly subject within 1st year.But believe me it is the most interesting subject. Just go through the diagrams and practice those diagrams as much as you can. Refer only B.D.Chourasia for anatomy.You can use Grey's anatomy as a reference.
• Physiology- This seems to be an easy subject but believe me if you are able to understand each and every topic of physiology then only you'll be able to understand Pathology, Pharmacology and Medicine. Physiology is basic science for all these subjects.understanding understanding of the subject, I would suggest you to read either Ganong or Guyton. I had preferred Ganong. Just make flow chart for each topic. Make it as simple as possible.
• Biochemistry- This is also a very easy subject. I have completed it in just 15 days. But let me give you an example- If a patient comes to you with his blood report or any other biochemical test which u have not read or you have no idea about what's written over there in the report then you won't be able to make any diagnosis. So the biochemistry is all about normal values. If you don't the normal values, you won't be able to interpret abnormal ones. So for that purpose, I suggest you to read this subject with your full heart and open mind. Honestly speaking I hadn't gone through the Lippincott but my friends who have read it are much better than me in biochemistry. So you should also go through it. From exam point of view, u can prefer Pankaja Naik. Again make flow charts here.
