You have to appear for NEET (National Eligibility cum Entrance Test) and have decent marks to take admission in any government college. The cut-off varies year to year but 570 is generally regarded as a very good score. You can find the application from the NEET website itself, and apply from there to appear for the exam. There are reservations and people holding SC/ST and OBC caste certificates can benefit from lower cut-off marks and lower admission or session fees. The process is pretty straightforward and I don't feel any necessary improvement is needed to the admission process.
