The Ivies may appear pure compared to the SEC, but they have ways within their scope to optimize results. Two stories from when I was in grad school at Cornell:
1) I was taking a grad level stats class in the Ag School (which was surprisingly rigorous). One day we were taking an exam and the class before us had clearly been assigning project teams as all the names were in groups on the board. I recognized virtually the entire hockey team. I also recognized that each group had one or more non-hockey players. Does anyone want to place bets on how difficult that class was? Care to speculate on who did most of the work in each group?
2) Cornell adopted a new undergraduate financial aid policy while I was there. This was before the Ivies went "no loans." While they insisted that the totality of aid was independent of the student and purely based on financial need (OK, sure), the type of aid they could get was based on "student attractiveness." One could be considered attractive with a 4.0, by being a world class cellist or by having a 100 mph slapshot.
Then again, even at RPI the guys learned to play the system. One year, when I was working in the Registrar's Office, virtually the entire team signed up for Helicopter Design. That was odd because there were no Aero majors on the team. It turned out there were two sections of a required Management class - one taught at a convenient time by a friendly, easy going professor that was known to be a relatively easy grader, and the other taught at 9 a.m. by a known ball buster. Anyone care to guess which section conflicted with Helicopter Design? Would you like to speculate what happened after schedules were released? I never checked, but I'll bet the farm the Helicopter Design prof was a season ticket holder.
Lastly, although it has nothing to do with playing the system but is hockey related and I'm in a story-telling mood: watching a good chunk of the hockey team sledding down the hill near the Pittsburgh Building on dining hall trays. I'm sure there was more than a little beer downed to help out, but Jim Salfi's boys knew how to make their own fun.
