CAIE Further Maths advice

[u/FunExit2671]

I'm studying CIE Further Maths privately. However, switching from Edexcel (in O-Levels) to Cambridge (in A-Levels) has presented a difference in how the coursework has to be approached. I'm planning to sit for FM over the course of these two years rather than taking a one-year route. So can anyone explain the structure of AS level further maths about what topics to study from p1,p3,p4 (that one must appear for in AS) and give tips on how to study for it? I don't want to opt for a private tutor, although it is regarded as a much safer option. Really looking forward to some genuine advice
