Hi,

Well if you want to apply and study medicine in USA then there you need to first complete your undergraduate in any subject along with pre medicine track and then go for MD for four years and there are hardly any scholarships available. Medical education is very expensive everywhere. In UK you can opt for doing MBBS but then again there also the education is pretty expensive and same goes for Australia as well as Singapore where MBBS is available as a subject. In USA you are supposed to give MCAT when you apply for your MD program. In other countries there is no such special exams available but getting admission for international students is highly selective and competitive.

I hope this help you.

Take care
