Guysss!
I really am freaking out right now..
I have done very few past papers...and i did fine. I mean i got an A on the mock- good enough!
I just did the latest exam... Nov 2008.
IT WAS SO HARD! AND JUST LIKE CHEM IM SCARED ITS GUNNA BE THE SAME!!!!!!! Seriously, what do you guys tihnk..and am I the only one that thinks this paper is hard??

hey there goin4dakill!! you'll be fine because:
1) if you know how to answer - you can score
2) you said you got an A in the hard mock - no need for panic
3) the threshold is low for p3 , usually being 55%  ;D

remember Bob Marley "Don't worry! Be happy"


Hey :)))
Thank you, I really appreciate that :)
Rep + for you luv
