First off, to the students coming here just after the 2017 Mathematics Extension 2 test, congrats on finishing 12 years of mathematics studies! And to my students that I’ve personally tutored, I’m very proud of all the hard work you’ve put in!
The folks grading the HSC papers generally take a few months to publish the solutions, but I know everyone’s dying to know if they got certain questions correct or not. So I’ve worked through all of the problems from the 2017 exam for you! I tried to include as much working out as possible, in case you were wondering how to get the answers (and for future students using it to study for their exams).
I found the 2017 exam was easy in some parts with some particularly difficult bits throughout. In particular, I thought Question 15 was a little more on the difficult side, and Question 16 was on the easier side than I expected, other than maybe 16aii, but that’s just me!
