If you're unfamiliar with the ATAR Notes Forums, welcome aboard - great to have you here.
Basically, ATAR Notes is a place full of students. Current high school students, current uni students. And for literally more than a decade, it's been a place where high school students can come online and clarify concepts they just don't understand at school, get feedback on their work, and just generally chill out.
The cool thing is, we actually have dedicated sections of the forums for specific HSC subjects. And
within those sections, we have individual threads where you can ask whatever questions you like about your subjects. Some of these have thousands and thousands of questions and answers. Others are pretty new. Below, you can find links to some of those threads - hopefully, this will make it easier for you to navigate the forums. It might be a good idea to bookmark this thread!
