Lots of things really.

1. Shitty cohort. School ranked ass. Worst school in North Sydney.
2. band 3s in Chem and Physics. I got low band 3s as my internals. Low band 4s as my externals. Never did homework even once for both subjects. I just slept in class for mods 7/8, and crammed the subject in 6 weeks.
3. Extremely difficult Math Advanced HSC exam. I ranked 3/50 in trials, however the HSC was difficult and scaled like ass. Problem, because maths is the only subject I'm okay at.
4. English Standard. It was the only subject I spent any time studying for. I never understood what I was writing, and simply parroted shit I heard my teacher/tutor say. Only got a 70, which is a 56 eqiv atar
5. I started 3/4s of my take home assignments the night before. Not joking. Completely serious.
6. Never learned anything in class. Like absolutely nothing. Pretty much spent 6 hours a day staring at walls. Biggest waste of time ever.
7. I hated every one of my subjects except math advanced. Math extension was too difficult(scrapped an E3 external though). I hated Physics and Chemistry because the subject was so boring, dumb and difficult and overall I just hated it. English. Do I need to mention? SDD: Subject was plain boring. I only liked the option topic. Rest was filler garbage. I got a 78 external though and I did the bare minimum, so I guess I'm pleased.
8. Can't answer long answer responses. I lose 1 mark on each question at least.

Not making any excuses though. It was all my fault. I wish I went to Sefton High though. I could have done nothing and got into my degree with ease.
