    What HSC markers had to say about last year's exam

    Resources for Standard 1

    It seems most of the maths courses now have mostly sufficient resources. Trials for Standard 2 (just as it was for General Maths) seem to still be hard to get (compared to 2u, ext. 1, ext. 2). But a scarcity of resources is even worse for Standard 1. So far we only have 2 hsc exams and books...

    Projectile motion with resistance proportional to the square of the velocity

    The syllabus is unclear as to whether this is required. Even some textbook authors have contacted NESA to gain clarity on this issue to no avail. Some texts include it. Some don't. In particular, Cambridge and Terry Lee don't. New Senior Maths and Maths in Focus do. You may be wasting your...
