I'm sitting this one on Tuesday as well, it will be my third attempt at it! Haha
Anyways last time i did it i got 57 according to my results sheet, that was a D but someone posted earlier that 52 is an A? Guess my actual marks were half that or something right?
Anyways i think my problem has always been knowing my stuff, last two times i found it hard to pick which questions to do because i felt i didn't know enough to be able to answer them well so right now i'm going through the book again and my notes and just getting it all together in my head.
