know the class 12 marks is not necessarily important in determining how you fair in your MBBS because most of the subjects will be biological and your concepts and interest in biology as well as your memory will be a key in how will you do in your MBBS level but yet I will evam aggregate of 50% in physics, chemistry and biology is required for the general category and 40% for the reserve category for you to be held eligible for qualifying in the Neet examination and apart from that also you need to realise that the solid concepts in 11 and 12 are most important in laying the foundation of most of your medical subjects taught in MBBS like biochemistry, microbiology, pathology and Physiology
so not performing fairly well in class 11 and 12 is not going to be particularly helpful in your medical career as well although it does not have any direct impact as such

Hello,
No definitely not much.
12th marks is used only for admission in colleges and there is ap minimum requirement of percentage in every college.So, don't worry about it and concentrate on your studies.
Good luck.

its not very definately i could say as you must hava minimum of 45% to get any MBBS admission where as if you have that much thats more than enough , while which matters is your NEET score you must have very good score in NEET around 550+ for MBBS admission in govt college

hope this helps
