There is a prevalence of mathematical deficits in higher education. This is exacerbated by the increasing number of students entering through non-traditional means. The ability to address these deficits, either prior to the commencement of an undergraduate degree or through the provision of additional mathematics assistance, is therefore vital for student success. This paper examines strategies implemented by a mathematics learning support unit in addressing mathematical deficits. As confidence is an essential component of learning, it is crucial that any course or assistance increases both confidence and mathematical knowledge. The two studies reported in this paper investigated student confidence levels upon commencement and completion of preparatory courses. The benefits of dedicated study spaces with tutor assistance, to encourage independent learning as effective and efficient methods of decreasing mathematical deficits was also investigated. The results of these studies highlight the importance of mathematics learning support units in universities. These units and their integrity should be preserved both nationally and internationally.
