Should you be looking at a college where the DoS have the same periods of history that you are interested in - or does that not matter eg if they are specialist in medieval history but you are more interested in modern history should you try to find a college with a DoS who has interests in that area?
Also as numbers of history undergraduates vary significantly per college should you be looking at a college with the most history students?
Also the stats on state vs independent schools per college - are they relevent? for example would those with high level of independent school students be better to apply to if you are a state school candidate?
