norcalmom2014: On this point I must disagree strongly. Your son may or may not learn a darn thing about economics or one or three other subjects where he has a professor that he doesn't get or even the one or two who are just really bad teachers. However, is that really all that different than any other staid university level institution? I think not, after all we all know of instances where someone pays a fortune for a top level University degree only to hear their child is being lectured by a graduate assistant over 50% of the time or take Brown University where all classes are graded "pass/fail" and the entire student body talks of how hard it is to get in and easy to get through... In any case I'll be shocked if when you get to graduation with your son in June of 2014 you don't see a young man who has learned a ton of things and grown tremendously compared to the one you dropped off at O'Hara Hall in July 2010.
Now wether or not he knows a ton about Economics on that June date in 2014 if he has Professor Cohn will likely depend on how well he and his classmates teach each other the actual material in the Professor's fairly well written text vice his classroom contact hours with the professor. However he and his entire class will likely well know how to deal with at least one difficult, slightly egomaniacal, narcissist, if not a couple, and really of the things one must learn to excel and be a leader in this life, isn't that a lesson he's likely going to have to learn at some point anyway, especially if he chooses to go to sea given the personalities of many ship's masters and chief engineers.
