We tutor 220 state school kids EVERY week to increase the number & diversity of excellent mathematicians. In Sept we double our cohort, so we need more great tutors. Can you spare 2 to 10 hrs per week, £27.50/h (it's a good cause). Pls send a note & CV to [email protected]

Exciting news: here's the cover of my book about Shakespeare and maths, coming out in April. I spent the last two years researching it, which took me from Portsmouth to Keswick via Stratford-upon-Avon. The most fun I've ever had on a book project.
