Course: Assumed knowledge (Mathematics Skills)  OpenDesk

Mathematics is often a part of university study, so it is important to develop the mathematical skills necessary for study within most disciplines. Resources are available for students who have maths anxiety or for students who are studying mathematics offcampus.
Current students can access a range of video snippets, and QuickTips can help them to develop their mathematical skills.
