DS is struggling to find ideas as to exactly what he wants to study - he is doing biology, physics, maths and product design A level (plus gold level EESE), and should get A, A, A, A with the A in biology. He knows he doesn't want to do straight physics, biology or engineering, and is thinking along the lines of medical physics (gets it from his mum), but is also interested in bio material engineering as he really doesn't want to move away from more practical design aspects that still play to his biology strength.
Any suggestions for things he might not have thought about?
