Hi

I'm extremely sorry to tell you dear about with 43 marks in chemistry in your 12th board examination you are not eligible for MBBS in afmc.

This is because,

As per eligibility criteria of AFMC to be eligible you should pass all the subjects in your class 12th in your first attempt  with English, Physics, Chemistry and Biology and must  get at least 60% in PCB  i. e Physics, Chemistry and Biology  and at least 50% marks in English and 50% marks individually in each of PCB , also should have studied and passed maths in the class 10th.

So, to be eligible for AFMC you should have got at least 50% marks in chemistry, that is at least 50 marks out of hundred marks but you have got only 43 marks and thus you are not eligible for MBBS in Afmc.

You can check the same at its official page , the link for the same is provided below
