This page has a variety of tasks designed for practice and revision. Practice questions are an important part consolidating students' understanding of a concept.

Errors - an appeal to users!
Few are infallible and we have all experienced frustration in finding errors in shiny new textbooks that we have just paid lots of money for! The advantage of online resources should be that as soon as errors are found they can be pointed out and corrected! When you find errors, please accept my apologies for the inevitable frustration it can cause but please also tell me as soon as you can on email@example.com so that I can correct it as soon as possible! Thank you!
