rumi1i1i1 I guess I was good in math, but I wasn't the greatest either at the start of year 11. I'll mainly apply this to probability because I was the weakest there and I often found myself being frustrated and hating it until like year 12.
But then yeh, ig i did that you said and I really tried to understand the ideas/concepts in probability and eventually it went from a struggle to a breeze in the exam. So if you feel like you're not confident in something, I suggest, rather than just throwing it away or rote learning, really try and understand the underlying ideas.
In regards to your question about SACs, I did a few questions from "easy" practice exams sort of like to practice ig lol, but I only used up my school's prac sacs like a few days before the actual sac(because I didn't get many only like 2 per sac). And I mainly revised for sacs by doing practice questions.
Hehe external resource 😅 the one i got a lot of trial papers from got taken down ;-; this year.... (rip vcetextbooksxyz 😔 )
And dw about asking this many questions its fine!! 😃 best of luck in year 12!
