Do you get the day off?
I only got the day off between 4u and 3u. My curriculum coordinator is strict.
Hmm. When you do past papers, I assume you mark yourself. Look at where you went wrong and ONLY study that. There is no need to study what you do know - what a waste of time. Then, once you have polished up on your weaknesses do the next past paper. Identify weaknesses, work on them, and do the next one etc etc ad infinitum.
Maybe go through the syllabus? I printed it out and ticked off everything, maybe did a worked example on a point that I was hazy about.
That's about it. My study on the day was a formula sheet my maths teacher had made for our class. He actually sells them now, but I don't know where - he left at the end of last year.
That's it. None of that study note crap. You only need the formulas for 2u and 3u (to an extent, 3u needs some logic). Lol, maybe even do some Sudoku or something, get some logical skills.
