Ds is in yr 11 and needs to make a decision about which A levels to take. He is pretty set on a maths degree. His school offers 4 A levels as a pathway in 6th form. He wants to take physics and chemistry, but I'm unsure which other A levels he should take, apart from Maths. Is it necessary to take further maths as well? It's not my subject area so unsure. He is expected to get 9's in all subjects except Enlish lit, which is 7. He knows his strongest points and is a natural mathematician
