Might be off topic but I'm kinda getting anxious for physics next year...I looked at VCAA 2014 a couple hours ago and literally couldn't do any of it even the motion and electronics section which made me scared lmao.
I think I'm putting too many expectations on myself already and expect myself to understand U3&4 exams with my U1&2 knowledge, sigh.
I wouldn't worry at all. You are definitely more prepared than I was. I doubt I even looked at a VCAA exam when I was doing 1/2. I had the exact same problem in specialist
this year. At the start of the year when our teacher gave us past exam questions I didn't know how to do almost any of them. If it makes you feel better, I honestly didn't understand a lot of motion physics, conceptually and otherwise, until we did dynamics in spesh haha.
My best advice would be just forget about looking at exams, you aren't expected to know everything already. Contrary to that, maybe try to use it as motivation; keep learning. Make a checklist of things you didn't know from the 2014 exam and tick things off as you do learn them. Just some ideas, but in the end don't worry about it., you'll be fine
