My DC has to choose one or the other to do in a year (year 11). He is bright IQ top 3% but has a processing disorder which means he struggles terribly to write fortunately this is compensated for by excellent reading and comprehension skills and a virtually photographic memory.
He was advised to do history in two years because so much writing is involved and I wonder if anyone on MN knows if there is a large amount of writing involved in either of these two subjects.
When I was at university those doing a psychology degrees told me that there was a lot found of maths (??) is there maths in the GCSE? It really is not his strong point.
