Where to start

The material is organised in two parts. Curriculum maths supports GCSE and A level study with lessons and practice. Extracurricular maths is for anyone who wants to follow an idea beyond the boundaries of a syllabus.

If any explanation here is unclear, the fault lies with the explanation rather than the reader, and I would be glad to know of it. Please get in touch to suggest any passages that need rephrasing/pages that need reordering; anything which overcomplicates an idea, and I will do my best to improve it. Thank you for helping to make this resource better.
