I couldn't find a Columbia vs. Yale thread for this year, so I decided to start one. Factors: 1) Quality of education? 2) Quality of teaching hospitals? 3) Quality of students? 4) Quality of faculty? 5) Research opportunities? 6) Location? 7) Residency match? 8) Prestige in medicine? BTW, I hear that Columbia is now P/F for the first two years (starting class of 2012). Can anyone confirm this? Feel free to consider other logical factors. Thanks in advance.
