Print Materials to assist with any pre-requisite mathematics required in USQ courses. These materials are based on USQ's Tertiary Preparation Program. Mathematics modules are presented in increasing level of difficulty and complexity from Level A through to Level D.

Comparing numbers (part of module only)

  • Comparing quantities of subtraction
  • Comparing quantities by division (including percentages)
  • Ratios (including ratios in squares, rectangles, circles & triangles)
  • Rates
