hmmm you wont be able to find anything back dating back to 1980 ... but thats nut, how do you balance with other subjects i mean each paper takes 3 hours or even longer to do or you must've been doing pass papers ages ago...
i was actually planning to do my 4 unit exam accelerated last year but in the end i didn't but ended up finishing 4U in the middle of year 11-i'm lucky now cos i got a lot of time and can do trials pretty quickly-btw ur sig is freaking awesome-is that from pizza?.
