Hey Krishna.

See the marks u have got is too low for u to bag a seat in the govt college to pursue ur higher studies in the field of ur interest under MBBS courses. In private colleges also u should be going through management quota to secure ur seat which will require a huge amount of money. U can also take a one year drop to start once again. About ur rank I m providing u a link for ur help.
