Considering medical school in the UK for an overseas student is £100,000+ and in another thread you said £47 a week for volunteering abroad is too expensive for you. Considering that is HALF my accomodation alone a week, how on earth can you expect to pay for medical school? You are looking at between £100-£250 pounds a week (depending on where in the country you go) WITHOUT tuition fees to go to medical school. As a overseas student, you are looking at £20,000+ a year tuition fees, with no loans or grants.
There is not going to be any scholarship that offers that kind of money. Most offer about £1000 or £5000 if you're really lucky a year from what I've seen. If your only way of financing medical school in the UK is to hope to be given the money, I think you need to seriously rethink your plans. You also asked what to do in your gap year in a different thread, don't waste money on travelling the world, you can't afford it. Get a job and try to start saving these thousands of pounds you will need to study here.
