### Success in Maths for IT

Students studying IT require a sound knowledge of mathematics.

To assist you if you have had bad experiences at school, not enough exposure to mathematics or the exposure was a number of years ago we have developed a series of videos.

These videos are based on the materials that is assumed in **MAT1101** (found in the appendix of your study material (USQ username and password required)).

To view files click on the topic you wish to refresh. A copy of presentation is available for you to download (Printable Handout).
