I have completed my worked solutions to the 2024 HSC Mathematics Extension 1 exam and will make the video walkthrough soon!
Thoughts on this year’s exam (link to the solutions is at the bottom of the post):
I found this year’s exam to once again be pretty approachable for Extension 1 students. I enjoyed the more novel questions and didn’t find any of the questions particularly awful.
My personal favourite question was Question 14(a), partly because I like differential equations, but also because I felt the question was relatively unique, bringing in the consideration of the function’s domain and range, and it made you think a bit.
My personal least favourite question was Question 13(d), because even though I normally enjoy integration, I initially mistook the 8 in the denominator for a 4, so I initially got it wrong and then got caught up trying to think how I’d approach it properly. That’s more my fault of course, not the question’s!
