Study abroad for cheaper?Watch
Also are you looking to study a graduate degree? I'm pretty sure that you don't study undergraduate medicine in the US, it's a grad school subject (not sure though I just read some other threads on TSR about this).
I understand your struggle, though. UK unis are increasingly expensive it's ridiculous. Would you consider studying in other countries such as Germany where tuition is very cheap/free? Or Bulgaria? Netherlands is good too!
