Ds has decided to go down the IB route rather than A-levels - he's doing English and history at higher level and maths, biology and German at standard level but has a dilemma with his third choice for higher level. He can't decide between philosophy and psychology. He enjoys and is good at philosophy but thinks the psychology curriculum looks really interesting. He thinks the clincher will be which is regarded as better by universities (will be aiming for Russell Group) - any advice please?
