Dear Future Doctor:
Thanks for your kind words. We hope that you would continue to find valuable information on iMahal and tell your friends about iMahal.
Entering a Medical School in India is highly desirable and extremely competitive. The basic education requirement is the completion of high school - that is, Grade 12. India does not have a "standardized test" for education in medicine. Each university or college has its own entrance exam. It is not uncommon for a prospective student to travel to multiple locations to take various entrance exams.
Each school has its own approach to handling International Students. We would advise you to contact prospective schools directly. You may have to do this via the postal mail, since not many schools have informative websites.
