A site where you will find very high-quality resources comes from Dr Jamie Frost who has produced resources (slides/worksheets) for the new specification.
Dr Frost has also written wonderfully clear instructions on the use of the Casio FX99-1EX calculator which you will find on his site, I have also included a link to this on the Use of Technology page.
To really challenge your students Dr Frost has created such a useful resource with his STEP, MAT and AEA questions all aligned to new A Level chapters. This document is 156 pages of categorised questions (brief answers are given). Also available is a pdf file of just the STEP questions.
For mark schemes see:
- MAT (Maths Admissions Test), see right hand menu, question papers, followed by solutions as separate documents. For superb resources for these questions see these Underground Mathematics Review Questions where you will find not only the questions but suggestions and complete solutions.
- AEA questions and mark schemes.
- STEP mark schemes (under STEP past papers). See also this post which includes details of a superb site for STEP questions; this site has free access to fully worked solutions for STEP papers.
Maths Challenge questions are an excellent resource at any time – not just for preparation for the competitions, particularly with the increased requirement for problem solving skills at all levels. It is possible to access Maths Challenge questions by topic for Junior, Intermediate and Senior from Dr Frosts’s wonderful website full of outstanding resources.
Very conveniently it is possible to download zip files of questions by topic.
You can also search the UKMT database by topic.
