My DS has just started year 12 and is taking 4 a'levels, with the 4th being further maths. He is coping fine with his main 3 subjects but is struggling with some parts of further maths, which is also making up the bulk of his homework, and affecting the time he can dedicate to his other subjects.
I have spoken to him about dropping it if it starts to impact his other grades, as he doesn't need further maths for what he wants to do but he wants to carry on with it. He is a really capable student, with all 9's at GCSE in his A level subjects but the jump seems huge.
Is this likely to be part of dealing with the transition to A level and will get easier or a sign that he needs to consider dropping it. How long should he give it a try for?
