Don't tell me you have graduated from high school and cannot even do a basic internet search, e.g. google "mbbs India." Get list of schools, check them out - admissions policies, application procedures, costs, etc. Should have done this well before graduating from high school to ensure you took all the prerequisite science & math courses.
How were your grades, class standing? Are you sure you are exceptionally intelligent, have a superior grounding in sciences & math, and have any hope of competing for a place in an mbbs school? No discernible signs in your post.
