Bendable twist-ties are used to connect straws when forming simple and complex geometric designs.

This study guide for Varsity Maths Preparation has been compiled by Emeritus Professor John Webb in response to the dire challenges experienced by first year university students, in Mathematics as well as in courses in Science, Engineering and Business Science, all heavily dependent on mathematical thinking. By working through the problem sets in this self-study book, learners should develop and test their skills, on their own, in areas such as algebraic expertise, trigonometry skills, word problems, geometric insight, numerical facility, logical reasoning and flexible thinking. This cannot be taught and is best achieved without assistance and timeously, i.e. prior to students entering university. The problem-solving techniques which learners could acquire from dedicated, independent use of this outstanding booklet will contribute significantly to their success in the National Benchmark tests (NBTs). Varsity Maths Prep is a gem for learners who are serious about an academic future.
