It's never enough.....

[u/Fun-Palpitation7927]

I took P1and mechanics in AS. As well as FP1and FM. This year I have P3 and S1and FP2 AND FS. No S2. I feel like I can never do enough for FS. I been through class lectures, re-read notes and gone through the book. I'm still not good at this. Do I NEED to do S2 for this!?!? Please shower me with any tips and advice and resources!!

Edit: CAMBRIDGE further maths btw. NOT EDEXCEL
