Yes, it is with Continuing Education and it is interdisciplinary. They have said that they don't yet offer the DPhil, but that the MSt course can be used to lead to DPhil work possibly at Oxford and that they may be able to offer you a place if suitable supervision can be found. It seems like they are interested in creating the programme at some point.
Could you elaborate on how the grading works? What does a 60, 70, 80 mean (in terms of frequency awarded and criteria for each)? I realize this is rather theoretical, but I am just trying to get a grasp of the context and standards, so please know I'd just be grateful for any light you can shed, as this is all foreign.

Also, I was curious to know how graduate students approach the reading lists, as in, do you read all of the books listed, or do your best or pick and choose, or is this a conversation with your Tutor or Advisor? Is there any general idea of how much of a reading list to try to accomplish?
And my last question involves being assigned to a college. Do applicants reach out to the desired college in any way, to state their interest? Is there anything that you can do to help your case? Thanks for your input!
