So getting back to the topic, it seems there isn't any real difference in the two schools other than size, facilities at eton a bit better, and the rest really might just be down to people's own experiences.
colleger I think I understand why someone would ask for advice to choose eton or Harrow, its where the question was asked that was daft and wrong wording.
In the first instance parents have to decide to apply, I think this is what that parent needed help with in deciding, once you apply it is then up to the school to "choose" you.
To parents unaffiliated there really doesn't seem to be much difference in terms of quality of education and curricular activities offered, the few differences seem down to preference, for instance I am not bothered by harrow's location at all, eton on the other hand is very far from where we live.
They both seem to be just as hard to get into, so will just have to wait and see.
headmaster advised against applying to both schools as it might not go down well with whoever is second choice, is this true ? Has anyone applied to both ?
