How to l get a medicine scholarship for international students in the UkWatch
b) depends on your circumstances. Sounds like you are either attending school in the UK or am attending an international school abroad. These for foreigners usually mean you are from a relatively well-off household (even if you are not, unfortunately you would be for most scholarship schemes offered by most countries/companies). You need to look at your own country's governments' offerings and/or private companies' schemes. Both of which are usually really rare.

International studying is a privilege and not a right. Therefore it is usually unattainably expensive for many.
