I’m Mr Shelswell, and in my professional life I’m a Maths teacher working in southwest England. These are some of my notes.

These notes were originally written to support the students that I had in Swindon studying A Level maths with the Discrete module of the old MEI specification. A couple of syllabus changes and a school move later I’m teaching in Bristol and finding that it’s time to update the content of the site.

The bulk of the content is currently still in the Discrete maths category, now part of Further Maths, a leftover from the original aim of the site. As I get time I will be adding to the content in other categories, and hopefully including topics that are not in the A Level, precursors to the course and work done at GCSE.
