How can I prepare for Year 13 Further Maths?
Besides integration and differentiation, very little overlaps with Further Maths.
However strong results in Maths, makes your fluency, speed and accuracy better - meaning it's less effort to learn new content.
In general the best plan is to focus on the new content only. CP1 Ch1, Ch2, Ch3, Ch4 Core Pure 1.
These topics will be the main focus:
In general students that work ahead - self teaching all of CP1 - tend to learn the content less well, and perform less well, than students who prioritise learning those first four chapters really well.
If you are working ahead the best way to do this is with the textbook or bicen booklets.
