### Success in Maths for Science

Students studying science 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 **MAT1100**.

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