Yep, I was rank 3 actually.. 95.5% in SACs. First rank got 98% (but As in exams) second rank 96-97ish (A and A+ in exams).. they both got 39 raw.
The teacher took marks off on technicalities saying "you won't get away with that in exams"..
So, I lost 3 marks in exams, whilst another member here lost 3.5 for a 50 .. 
Well MAtty, the achievement is that you powned the exam, so congratulations on that!

Although, I know how badly SACs can hurt..
IT Applications:
GA 1: 74% -----> 86%
GA 2: 75% ------> 86%
GA 3: 150/180 (A+)
SS: 39
Some guy here got 135/180 and ended up with an SS of 42...I was rank 3 or 4, in a cohort of 10. Basically our teacher turned out practice SACs into real SACs, let us take them home (and thus no one ever knew what mistakes we made, but the dropkicks collaborated) etc.
RAnk #1 managed an A+, pulled out a 42 (so i presume it was low) Rank#2 must have gotten an A, he got 36, rank#3 was a complete dropkick, collab'd with friends to get top in SAC, he probs got <25.
