This page features free HSC extension one maths questions organised into exam style topic tests with worked solutions. Unlike the other subjects on this site, these tests will be of varying lengths as each topic has a different amount of content and I didn’t want to write tests that ask the same fundamental question multiple times. Each test includes 5 multiple choice questions and 1-3 15 mark short answer segments based on the amount of content in each topic. If you happen to find an error in any of my papers, contact me and I’ll fix it as soon as possible.
