You'll actually find that the Oxford summer school has a quite unique
atmosphere. It manages to be both socially relaxed and intellectually
intensive in a uniquely Oxbridge-in-summer kind of way. I suspect that most
people come away feeling that the formal lectures were not the most
important part of the experience.
