I don't believe organic chemistry is intentionally used to cull out medical students. Instead it is simply the difficulty of the course, which by-the-way matches the learning situation in medical school: My organic chemistry course was excellent until the half-semester, whereupon the professor's well-organized and insightful presentation ceased. Instead we were confronted with a plethora of memorization with little organization. The change in teaching method and learning was obvious to everyone in the room. We questioned it and the professor said apologetically "That's the way it is! It's hard! I'm sorry!" Within a week a large part of the class dropped and many of the remainder became more reclusive and protective about their study. So much must be memorized in medical school that the process alters the way students think. I watched an excellent scientist fall away from science (but become an excellent memorizer) in medical school. Once a brilliant researcher, now a doddering encyclopedia of (sometimes incorrect) facts. Sad.
