My eldest wants to do medicine and took physics, chemistry and biology at standard grade level (equivalent of GCSE).
In Scotland there is not the option of doing a combined science course, but there is still a reluctance on the part of schools to allow pupils to take 3 sciences. I went to a meeting at the school where the depute head said taking 3 sciences severely narrowed your child's future prospects etc etc.
My son did 3 sciences, and at higher level he is continuing two of them, with the intention of picking up physics again in sixth year.
My younger son is doing physics and chemistry, his other subjects are identical to my elders choices - English, Maths, French , History, Music but he is doing computing instead of biology. Strangely there is no objection to this combination.
Te depute teacher also gave incorrect advice on University courses to several parent whose children wanted to do dentistry and vet. medicine. 3 sciences are definitely required by some Scottish Universities to do these subjects.
There seems to be a bias against science in some schools.
