the last time i did my theory exam was in 2003 and that was grade 5..i only got a merit of 85 though..n to tell u the truth, i sorta HATE theory i dunno y..so mostly i did last minute work with sum huge pushing from my teacher
after that i didn't take any more exams since all i needed was a grade 5 cert to go all the way to grade 8 in practical..so gud for you, personally i feel theory is juz like any other academic subject, u'll do well if ur interested in learning it..which i dun although i noe its important..so keep doin ur thing n it wont b too tough. anyway,congratz!
