Remember guys, I'm writing all this up for your benefit in my spare time, it has took me 2 hours - 3 hours to write all this up reading each part carefully. Reason why I'm telling you this is because the specification of edexcel rounds everything up in 30 pages, it doesn't give detail. It just tells you to learn some stuff e.g. trigonometric functions, use a calculator effectively, not detailed stuff like sometimes when you have to use cos in a equation on a calculator. Also, this is in order of how you should learn it, that specification is in random order. For example, you need to learn factorising for quadratics.
