yeah i heard that if you work practically all the hours you can, you can earn about £35,000 a year in F1. if you're worried about studying for five years, you shouldn't apply for medicine. nowadays, it's all about life long learning, so it's not just the five years, you're be learning basically until you retire.
also you should try and get some work placements. about 3 will be perfect if you can get them. make sure you organise them quickly, otherwise all the slots for the holidays will be filled and you'll have to do it in term time at the beginning of yr 13 like me. try to get placements in different areas as well. GP is quite easy to get into and surgery is quite fun/interesting. if you can organise it yourself, it shows initiative, which looks good. don't try to do too much volunteering just for the sake of it cos personally i think it looks a bit obsessive, unless you really want to wipe old peoples' arses. the best thing to do if you don't want to volunteer is to get a job. you gain experience of teamwork etc and you earn money.
try to get involved in some school sports and try to get a position of responsibility at school. it show's you're mature and can handle responsibility etc.
the best advise i can give is to find something to do in your spare time that develops your skills in teamwork and working under pressure and that you enjoy. too often people do activities just because they think it will help them get into medicine but don't actually enjoy it. in my opinion that's just a waste of time.
by the way i got an offer from cmbridge for medicine 2007, so if you want any more advise just PM me.
