Hello aspirant. I suppose you asked about which books to study to get admission in MBBS course. So for that you will have to qualify NEET with at least above 620 out of 720 for top government colleges, or else even after having 50 percentile you are eligible for MBBS but no good colleges take up admissions at that low percentile. Your category will affect too. I have told you the scenario for general category.

Regards
