not being a show off or anything but i am just posting the stuff below so that people dont freak out.
if you havent been studying and are feeling stressed out, DONT!!!!!! In all honesty even though I told myself last year that I would at least study sometime during the summer holidays and do my notes, however it never happened. In fact I did ABSOLUTELY NO STUDY!!!!!!
so although it set me behind a lot, I played catch up during Term 1. Yes it was difficult at times you regret not studying during the holidays but if you can put yourself an extra few hours ever week to play catch up for the summer holidays then your set. Because I did absolutely no work during the summer holidays, I had to give up an extra 3 hours of social every week to do my work such as notes and stuff. It can be an ass but it is possible.
If you can absolutely do work this holiday then do it as it will make term 1 much easier but dont be a freak and over do everything, you either burn out or you will regret it as it is kinda your last opportunity to go out as much as you can.
If you are going to go out throughout the holidays (like I did) and do no study, make sure you can play catch up!!! If you know you cant catch up start motivating yourself to do some work. Even if it is 1 hour a day. Thats enough to get you going. You dont need to be crazy and do like 3-5 hours every day...
I regretted not studying during the summer holidays but I managed to play catch up and still got an atar of 99.30. So dont be stressed. If you are someone who is capable of doing study and a bit more studying during school, then you are completely fine. In the situation you can't, now is the time to get moving. You can still socialise and stuff now but be ready to give up your last week of holidays to prepare for school and stuff.
just my two cents to those that are stressing.
