I graduated from both Oxford and Emory. I think a good way to think about Oxford is rather like how you might look at an honors dorm program at a large university. All of the students at Oxford are highly competitive in terms of grades/scores and the smaller environment encourages a tightly knit community - a situation that is beneficial for college students that are seeking this type of fit. Another thing to know is that because the class sizes are small, many classes feel more like upper level seminars where group discussions of the subject material are encouraged and each student has a voice in the discussion. My professors were excellent and, because I had an actual academic relationship with them, they were the ones I asked for graduate school recommendations. Oxford is not for everyone, but if you are the type of student that is looking for a smaller supportive environment to start with and you also want to later experience studying at a larger university then you might consider it a good choice.
