As a black and white book, at first glance this might appear too dull to be something you would use as a study tool; don't be fooled by that. The notes themselves are very well laid-out and are always supported by worked examples. It's not as bright and colourful as other revision notes/guides but it was invaluable tome during my highers and even as a back-up for university.
my daughter wasn't doing as well as she hoped at maths,so i bought this book. she feels it's made a difference to her studying and she has a better understanding of the subject now. as she's gone up a grade,something's working so it's been worth buying.
