^ i think i heard that to get in to medicine at queen's (belfast) you need 6 a*'s at gcse, in addition to straight a's at a-level...
but yeah, some jobs just plain are oversubscribed. like forensic science.
(a) there are about 3 jobs in the whole of the UK for it.
(b) you can get into it with a chemistry degree, as far as I know, which'll leave you with lots more options for jobs.
hmmm, it's mostly tv programs that oversubscribe these jobs... too many people watching ally mcbeal, ER and CSI, methinks...
I'm just waiting for a degree course to be announced for "survival on a desert island if your plane crashes on it..."
;)
EDIT: i also agree with petre- don't necessarily go for the jobs that are totally undersubscribed, since they'll be the oversubscribed jobs of 10 years' time, since the pay will rise so much that everyone will want to do it.
