its all well and good to be prepared going into next year but please remember to take this time as a break too. year 12 is a lot and for me these holidays were the last proper break i had all year. balance is key!
stay on top of your notes, if youve fallen behind in first term, work on them now and consistently add to them every week. i feel like the reality is that there are 4 topics in every subject for 10 units, there are things you are going to forget so having good notes to fall back on when you need to revise is important. having already done the content throughout the year, by the time you reach trials/hsc it wont be unfamiliar and will likely come back to you quickly. working consistently throughout the year enabled me to go lighter on study during the hsc. ofc there were topics i forgot and needed to revise, but they shouldnt be unfamiliar if you put work in consistently. You have a lot more time than you think during the hsc asw, depending on your timetable you could have a week in between subjects which is plenty of time to revise - by the hsc itll all come back to you, for now i wouldnt worry about forgetting and just start to be consistent in your study
