Thanks so mcuh for the response! I'd put examples but everythin you said is applicable to what I need to do! I am just stressing because I haven't been spending a lot of time on math.
By the way my first assessment is 10%. If I get in my 60s or 70s, do I still have a chance of getting a band 6?
Short answer to that question is yes. Band 6's don't vanish that easily. (I could give a long version but it's too early into the HSC for that)
Well given you're aware of the time factor then you will want to get a start there. It just means you need to practice more and practice more.
Although, don't wear yourself out either. Don't exhaust you to the point that studying/preparation becomes ineffective. Also, make sure to focus on relieving the stress first. You can't get as much done whilst stressing than when you don't. That doesn't necessarily mean to just stop stressing; it just means to put aside a sufficient amount of stress and get started (once you start studying you may feel the stress disappears).
