If you do not need it for the maths, you probably do not need it.
Inside the book it has sections on reading and making notes, working with diagrams, learning and using mathamatics, working with numbers and symbols, different ways of studying, studying with a computer, observing and experimenting, writing and assignments and tackling examinations.
It does refer in S103 to the book but i have not bothered. So i would probably save your money.
