The 14 questions CAIE examiners themselves flagged as the ones candidates get wrong. I went through recent 9709 examiner reports, collated the questions singled out as the most challenging, and wrote a complete step-by-step worked solution for every one. Covers differentiation, integration, differential equations, complex numbers and vectors. Includes question booklet, mark scheme AND full worked solutions. These are the questions that separate A/A* candidates from B candidates. Free, and used with my own A Level classes.
