Hi

To become a doctor you need to do mbbs and admission in mbbs is through neet exam but arts student are not eligible for neet.

So, being an arts student you cannot become a doctor.

Still, you want to pursue mbbs and be a doctor?
Here's the solution :-
Go for  NIOS on demand examination for 12th  with all the  5 subjects including physics ,chemistry biology/biotechnology and English and for the 5th subject you can choose any subject of your choice like Hindi ,Sanskrit, maths or any other subject and after passing,  if you fulfill the percentage requirement in PCB i. e

at least  50  % in aggregate of PCB  i.e Physics, Chemistry and Biology/Biotechnology  in 12th examination  if belongs to general category , or   at least  40%  in aggregate of PCB if belongs to  Obc/ Sc /st category  , or at least 45 % in aggregate of PCB in case of general pwd candidates to be eligible.

If you fulfill this then,
you will be eligible for neet  and after qualifying neet you can get admission in MBBS on the basis of marks obtained by you in the Neet examination  and after completion of mbbs you will become a doctor and can practice.
