I was just in need of some tips & tricks to prepare for upcoming trials in regards to study and how I should be doing it/what prep is going to be the most beneficial for each subject. I'm currently studying Ancient History, Adv English, General Maths, Senior Science and SOR2.
Thankyouuuuu 
Hi!
I have basically no overlap with your subjects, but as a general guide:
- Ancient History: Have like a cheat sheet with all the stats, dates that you need, practice writing essays in timed conditions
- English: TQTE tables (Themes/quotes/techniques/effects), write them on separate cue-cards based on theme, practice under timed conditions. Familiarise yourself with all the rubrics for AOS and your modules
- General Maths: Do questions from each topic from all varying levels of difficulty, once again building up to doing previous trial papers under timed conditions. Key thing here is that you have to go back and mark :|
- Senior Science: Once again, past papers. You may have some formulas/equations that you need memorised, which in that case, also compile a sheet with all that you need. Go through the dot-points and rank them based on how well you know them, and work on the ones which you don't understand.
Not sure about SOR2, hope this helps!

EDIT: You'll notice that the common theme is past-papers. You may have heard this before, so much that you're possibly tired of it, but they honestly are the best way to pin-point exactly what you need practice on [certain topics/creative writing/extended responses etc]
