As per title really. DS is interested in taking A Level Physics and/or Computer Science, both of which suggest you take A Level Maths as well. He is fairly ambivalent about GCSE maths (although quite good at it), whereas I think he should have more of a passion for something he is going to study for A Level.
A colleague suggested that their child had found A Level maths much more interesting than the GCSE, and I wonder if others think this is the case? (I appreciate this might be very individual!)
