What is a biology interview at Oxford like?

It's not as scary as it seems! It's a good idea to look through your personal statement and make sure that you can talk well about anything you've mentioned in it, but don't be surprised if they don't ask you about it- the interviews are supposed to test you on things you haven't seen before. The number of interviewers in the room is variable, and you will get two interviews, one at the college you applied to, and one at another college. The interview is not an interrogation, more of a discussion to see how you think, so just try to relax and think through the problems they give you. They are likely to give you a graph, photograph or biological object to look at, which will then stimulate more questions. Lastly, remember that the interviews are supposed to determine whether you would work well under the tutorial system, so speak through your thought processes and ask questions if you need clarification.
