ive just done my GCSE's and i am gonig straight on to A Levels. i know exactly how u feel. coz after that.....i have to go to Uni. the thing is, like you, i dont want to. i want to take a break!
and i am!
i am going to New Zealand, get a work permit and work there for about 6 months, either go somewhere else or come back.
