but the kids who truly do well in my school are those who are involved in such activities. Not the ones who spend every living minute of their lives studying. And this is from a selective entry school viewpoint.
Strange how that works.. Doing better with less time to study.
As someone who completed VCE nearly a decade ago (that hurt a little to say), I found that the hardest part of VCE wasn't the content, it was having the time to study for SACs during terms 2 and 3. This is where a lot of people burnt out, myself included. Term 1 and 4 where very manageable as term 1 was easing you into the workload and term 4 was only 2-3 weeks long with no SACs and was essentially revision (well it was for me at least).
I'm not sure what school you go to, but maybe next year pick a Unit 1 & 2 subject in an area you're very confident in i.e. if you're good at English, do an english subject and vice versa, then in year 11, pick 1-2 Unit 3 & 4 subjects. This will boost your confidence a lot as you'll begin to see that VCE isn't the monster you've pictured it as.
Also, pick subjects you want to learn, don't just pick it because it's easy. Trust me on this! It also means when you study you'll actually enjoy what you're learning and won't see it as a massive task. I remember reading a post years ago from a guy who said when he was studying for Methods and Specialist, it wasn't about knowing how to do a specific question, it was about learning Differentiation and the whole purpose of it. So basically fully understanding topics. He went on to do extremely well in VCE and at University.
I learned about physics in physics, rather than learning how to answer textbook questions. I learned about maths in maths class, not about how to answer textbook questions. I learned about networks and security and algorithms and project management in software, I learned about improving my sentences and vocabulary and about ways people use language to convince you of a point and what to call those things they do with their writing that you don't have a name for in english. I spent this year learning. Not stressing or working or memorising, learning. Then the scores sorted themselves out, and that turned out okay.
Just out of curiosity, what subjects are you thinking of doing?
