Hello Aspirant,  In MBBS the minimum eligibility for the course is 10+2 with subjects with a minimum of 50% marks in Physics, Chemistry, and Biology.  If this elligibility does not cross then he will not get college. But you can do one thing,  you can visit in private  MBBS college and check their elligiblity criteria. 

Hope your doubt is cleared still if you have any doubt then free to comment
