Hello student,
In order to get admission in the MBBS course through the 85% state quota of Assam , you need to have completed class 7 to class 12 in Assam itself.
PRC is mandatory if you want to apply for state counseling in any course(also MBBS). If you don not have PRC you can apply for it online. Nowadays, the Assam Government provides e-service for applying online for this. You can do it from UMANG app (provided that you got a Aadhar card). You'll also have to submit some documents like land holding certificate or electoral roll verification etc. You'll be required to show the purpose of this document (like admission form or brochure mentioning its necessity).
You can go through the below article for details:-
