VCE Specialist Unit 2 Skills () « back to units

The skills below are aligned with the VCE Specialist Mathematics Study Design 2023-2027. Skills are organised into key areas: Simulation, Sampling & Sampling Distributions, Trigonometry & Reciprocal Functions, Transformations of the Plane, Vectors in the Plane (2D), and Complex Numbers (Introduction). To master a skill, you will have to gain 10 stars.

There are 3 levels to each skill,

  1. Easy: A star will be taken away if you get 3 consecutive wrong answers.
  2. Medium: A star will be taken away if you get 2 consecutive wrong answers.
  3. Hard: A star will be taken away on each wrong answer.

Most skills have multiple types of questions with varying difficulties. If you keep getting wrong answers, the system may give you the simplest question to answer. The idea is to have you master these skills with a ground up approach. If you get an answer wrong, you can read the solution and helpful tips that briefly explain the skill/topic you are practising.

All the best with your VCE Specialist Unit 2. If you see any issue, please do report it by clicking the red button at bottom left of this page.
