For the Diagnostic tests, the core mathematics syllabus has been divided into six main topic areas: Arithmetic, Algebra, Geometry and Trigonometry, Graphs, Probability and Statistics and Matrices and Transformations. A calculator is allowed for all the tests apart from arithmetic.
The Learning Module programs cover a variety of 30 different topics ranging from multiplication and division of decimals to frequencies, 3-dimensional trigonometry, and determinant and inverse of matrices. Each section provides the student with the useful option of selecting Notes before attempting to answer the questions, and the examples are then worked out step-by-step on the screen with comments to clarify the various stages.
I haven't done any serious maths for many years but I found things coming back to me after working through the Notes. The Study Aids booklet too, is an excellent source of information, and the package as a whole represents a powerful interactive revision aid.
