I used to know that : stuff you forgot from school
(Book)

"A Reader's digest book"--T.p. verso.

"First published in Great Britain in 2008 by Michael O'Mara Books"--T.p. verso.

This small but mighty collection will trigger your memory with fun facts you learned in school--from adverbs to the Pythagorean Theorem. Covering a variety of subjects, it features all the most important theories, equations, phrases, and rules we were all taught years ago. The information--presented in easy-to-retain, bite-sized chunks--is accurate and up-to-date. It will touch a chord with anyone old enough to have forgotten half of what they learned at school.--From publisher description.
