A2 Applets

These have been AI-coded to provide hours of practice on many of the examinable skills for your A2 Mathematics Examinations.

Please note that, whilst I have tried as far as possible to match the questions to the WJEC specification, there may be gaps in coverage and missing topics. I will continue working on this as time allows!

Note that these applets are designed for web browser, and may well not display correctly on iPad or mobile devices. For best results use a computer/laptop!
