Hi - fortunate enough that my son has been offered a place in S1 at both (currently at a State Primary in Edinburgh). He is academic and bright but not sporty. How do the two compare? I know GW is co-ed whereas SM is split but I have heard that boys do better in a co-ed environment? GW is a lot bigger but seems to have more clubs and facilities in the one campus. Torn between the two, to be honest!
