I was class president for 2 years and think I did pretty well. The key for me was communication - letting the rest of the class know what was coming up, what to expect, etc. We consolidated the exam schedule and just tried to make dental school a little less painful - threw a couple social events and stuff. I also got to know most of the instructors/administrators and talked with them regularly about things that were concerning the class. There was plenty of BS, but for the most part I enjoyed doing it.
