2011 - English. 1/130-odd in SACs, my indicative grade was 97 or 98, and I lost no marks at all for C&P. Came out of the exam feeling I'd done my best - B+ on the exam, 5/10 on C&P, which was my strongest area throughout the year. Came out with a 39 instead of the 43+ I was sure I'd achieved.
2012 - all my classes. Enviro Science I had an indicative score of 98, 1/15 for SACs, and got A+ on both exams, along with two other people in my class. It turned out that my cohort had a lump of awful achievers at the bottom on exam 2 and high achievers at the top, so somehow the top three in the class got pulled down slightly. I thought that the person with the highest SAC marks wasn't subject to moderation, but I was expecting a 43-48 for sure with the marks I got. Still, 42 was fine.
Chemistry, all my practice exams were A/A+ and I didn't mark lightly. SACs were very high A, I think 7/46 in the school. Had a nervous breakdown in the first exam and got a B, but I studied hard for Exam 2 and then screwed up two large questions that were also in my area of strength due to being unable to interpret properly. Came out feeling fairly calm and expecting an A, with the 35 I'd been aiming for, ended up with B A B+ and 33.
Methods, I was ecstatic to get that A+ on the second exam, and I definitely put a lot of blood, sweat and tears into this subject, but my first SAC mark was so bad it pulled my 89 average down to 82, and I lost two marks on Exam 1 (realised a day after I walked out I'd lost the A+) for something really simple, and while I definitely exceeded the 35 I was aiming for, the amount of preparation and intense study I did for the Metods exams felt like it didn't pay off quite enough overall. I feel like none of scores in 2012 were indicative of my internal grades (except Methods) at all, and I feel like I wasted a lot of time and effort to get the scores I did.
Overall ATAR I was happy about, though, it got me into my dream course, so I'm all set for a fresh start in a sensible system!

...it feels good to get that rant out. Really good.
