I want to apply at oxford. Who would be the best to get recommendation from ?

Like I mentioned on the other post, I don't think Oxford is still accepting applications for the 2010 intake. However, if you do decide to apply to Oxford (either now or in future), the best thing is to get recommendations from former professors of yours. I believe that Oxford doesn't seem to pay much attention to professional referees, except where one's been away from school for a long time (more than five years I'd say).
