A level Further Maths- ResourcesWatch
The fp1 and fp2 books are big study areas whereas the fm1/fs1 book is less than 150 pages - so to pass the a level - all fp modules would not be the easiest route.
The fp modules do have things that I’m interested in such as comic sections, mobius transforms, group ring descrete math etc. So I will learn this as my intention is to learn for university rather than the exam.
As a general point, the questions for fm in those books at least change emphasis from ‘here is a method please use it’ to ‘logically reason your way to x using all you know’.
For resources- I'd recommend the Pearson Edexcel textbooks, I got mine from Amazon but there's loads on depop, ebay and stuff for cheaper prices. Other than that - examsolutions and physicsandmathstutor.com have good resources too.
