This is a useful tool for any student revising for their A Level. It is not as detailed as a textbook would be when explaining the basic principles or going through worked examples but instead just outlines what the priciples are. Each element of the course is accompanied by a quick multiple choice set of questions and two examination board questions. It is a shame that there are not more of the latter as it is practice that makes perfect and to have three of four years worth of specific topic related questions would have made this far more valuable (You'll just have to trawl the internet examboard websites for those instead). I feel it would also have been better if the mark schemes had been in a seperate area instead of immediately following on from the questions, this being too much of a temptation to view instead of the inevitable struggle first.
