I haven't been put up a year, but I've basically learned everything I need to complete my GCSE's, so I don't really need to go to lessons again, until I come back in year 12 for my A Level stuff. Pretty much the same with me about top in the year, but strangely, no-one refers to me as a "nerd" because I'm very musical, with me playing loads of instruments really well. I think it's just that when they hear me play, they all forget how extremely clever I am. Which is obviously a good thing. I'm really into Performing Arts as well, so that's another reason not to call me a nerd.
Have you finished school yet? I might just skip the last two weeks over here, because I really can't be bothered with it, but my parents will probably force me to go in, so I'll just go into a computer room and do nothing but chat on MSN, and play games.
