## Mathematics Skills

### Success in Maths at USQ

#### 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)).
