I Used to Know That: Stuff You Forgot from School (Unabridged‪)‬

Can you remember how photosynthesis works? Well, what about quadratic equations? Or the names of all the Bennet sisters in Pride and Prejudice? How about Henry VIII’s wives, conjunctions, inertia, the continents of the world and the Seven Deadly Sins? And what on earth is the point of pi? Let’s face it, there are an awful lot of half-remembered things floating around in our heads.

This witty and very insightful book gathers together the facts, fiction, figures, and formulae we all learnt at school, and is guaranteed to have you exclaiming, ‘I used to know that!’
