VCAA 2018 Chemistry Exam Provisional Solutions
Solutions by Kevin Mao at TWM Publications

Full worked solutions available for Section B only. Section A has answers but no working or justification. We'll get to Section A some day, but most of you would've forgot this exam by then lol. Enjoy!

From the people I asked, the general consensus was that it was easy, however it was quite long. Idk what's up with the mostly easy exams this year for math/science.

As I expected, the exam was extremely long just like the 2018 NHT. Although I’d say the content was much easier. Perhaps even easier than last year’s.
