Serious software for the A level student is pretty thin on the ground as most companies focus their attention on the primary market. So it's a pleasant change to find a detailed and comprehensive revision and tutorial work on a subject which causes many headaches in A Level and additional maths classrooms.

Vectors is a set of fourteen programs which may be roughly divided into tutorial and testing. Each subject block is dealt with using graphic illustrations, animation where necessary and clear unambiguous text. It covers a wide range of topics under the vectors' umbrella including general principles, dot (scalar) product, ratios, three-dimensional vectors, the right-hand rule, the Cartesian equation and vector/plane intersection.

For ease of use, each program leads into the next and you can choose in the end-menu, either to run-run that section or chain the next one. The whole suite is easily transferrable to disc although no menu is included. The handbook sets out clearly the objectives of each section and, within the programs themselves, it's not possible to progress until understanding of that section has been reached.

Well written, well presented and clearly produced by someone in education (a senior lecturer in maths), it's good value for money and an excellent revision aid for the student.
