My only slight criticisms of the book are that on a few occasions, i.e. transforming graphs and dividing fractions, the help is constrained to the “how” of it, with not the why. And that Colin dismisses completing the square as pointless, but I feel that it is great for explaining the quadratic formula, is useful for seeing if a graph has real solutions and has its uses for higher level polynomials for those who go past A Level.
Colin and I differ on our opinions on the best way to complete the square, but his explanation of the equating co-efficients method is superb.
If you, or someone you know, is struggling with any of the topics involved in C1 then I would certainly advise buying a copy for your kindle. It is far better than any of the other C1 revision guides I have come across, and would be worth the money for the jokes, or the story of “bad guy x”, alone!
