FP1 definitely looks interesting!! How have you covered C1-4, M1, S1 already? That's a lot! I plan to do just the AS so EDEXCEL FP1, D1 and either M2/D2. Im doing C1,2 M1 in lower sixth - Is FP1 understandable and fine while doing these or will it be confusing and need knowledge of C3-4?
I am going to ask my school if they'll let me take the exams on Monday so hopefully they say it would be fine.
