Hi guys, I didn't find a thread for this and thought I'd make a revision thread for the C4 exam where we can talk about Qs we might be stuck on and help each other!

Anybody else having trouble with the finding of differential equation from data given?

These type of questions appear rarely and is usually the last question or so. Is there a special technique you can use in these questions?

I don't there is a special technique, you just need to understand the context well, when forming the equations.

Yeah, I'm not very good at understanding those questions, especially those chemical compounds and Newton's law stuff (I didn't select science subjects for A/L nor O/L).
Really want to get an A* for Math

i need approximately 90 too for an A* hope we'll get it btw, dont worry about not finishing the book yet, you still have time until 21st june and its easy to finish the past papers once you know the topics..
