Talk:A-level Mathematics/OCR/C4

I started on the differentiation section (first contribution, woo). But I'm studying for the Edexcel syllabus. On top of that, I've learnt most of C4 myself, so no guarantees on reliability. I took a brief look at the OCR syllabus, and they seem more or less similar. However, since I haven't actually looked at any past exam-style questions from OCR papers, I have no idea what the specific requirements are, or what common problems with solving questions are.
