I'm going to be spending the next year studying at Oxford, which is exciting to say the least. Here are a few things I'm looking forward to:
Old buildings and traditions: I've always enjoyed wearing robes and I hear that there are a number of events each term at Oxford for which formal academic dress is required.
Botany: unlike Emory, Oxford has an entire department for Plant Sciences. There's a Botanic Garden and herbarium in town, and Kew Gardens isn't far away.
Tutorials: in a tutorial, two or three students meet with a faculty member each week for discussion and the students are assigned readings and work to discuss next week. Tutorials allow for very flexible and specific study.
I don't know how much culture shock to expect. I enjoy standing in queues and not making eye contact on public transportation, so that's a start, I guess.
