MathCentre is a very large repository of tutorial videos, interactive assessments and PDF handouts to help with maths topics, roughly at A-level. This link is to a range of topics selected as relevant to Economics. The materials are categorised by area (such as Algebra, Arithmetic and Differentiation) and by individual topic.
Assessment Materials in Maths for Economists
This course webpage supports an introductory module on quantitative economics as taught by Fowad Murtaza and Domenico Tabasso at the University of Essex in 2009/10. It introduces students to the methods of quantitative economics, i.e. to how data are used in economics. Beginning from an elementary level (assuming no background in statistics), the course shows how economic data can be described and analysed. The elements of probability and random variables are introduced in the context of economic applications. The probability theory enables an introduction to elementary statistical inference: parameter estimation, confidence intervals and hypothesis tests. With these foundations, students are then introduced to the linear regression model that forms a starting point for econometrics. It includes a course outline / handbook, lecture presentations, lecture notes, coursework assignments, problem sets with solutions and statistical data.
Mathematics for economists is a course webpage produced by Dieter Balkenborg of the University of Exeter, the 2008 version of the course was taught by Juliette Stephenson. The material includes lecture slides, class exercises and solutions, homework tasks, and exam papers, usually made available as PDF files. Also includes links to previous versions of the course stretching back to 2001.
Three short (15 minute) tests are archived here, using a cross between multiple-choice and multiple-response questions, totally 26 questions.
This is an online tool that creates paper exams in the key mathematical skills required for Economics. It generates questions randomly, lets you choose which ones to include and then print out separate question and answer sheets.
