DS is doing his Year 12 mocks. He's doing Further Maths which, at his school, means doing the whole A Level syllabus in Year 12 and the Further Maths syllabus in Year 13. His 'minimum target grade' (from school) for the maths A Level is an A, and he is personally aiming for an A*. Like most year 12's he has found A Levels a step up from GCSE, though his internal assessments have generally gone ok. Now that year 1 is complete, for his maths mocks he is taking the equivalent of full A Level maths papers. His experience of sitting a couple of past-papers at home, and of the exams themselves, is that on each paper there are questions that he finds very unfamiliar and difficult. He attempts them, but struggles to complete them. My question is this ... are the A Level maths papers deliberately designed to stretch the more able by including questions that will be unfamiliar, or should students aiming for top grades expect to be able to fully tackle most of the questions?
For context, DS has never needed a tutor in the past, but I'm now seeing him thrown off his stride for the first time and wondering if this is par for the course of whether he needs some help to get back on track.
