If the plebe fails one course. Then the plebe will take summer school. Summer schools starts the week after graduation and goes until the end of Indoc. If 2 classes are failed, then a setback or disenrollment happens. It's up to the Academic Review Board.
True, people have gotten out. It is more that the people in band complain about being there, but don't actually do anything about it. Why they don't do anything about it is unclear to me.
I am currently a M/N in band co and I can say personally that the band is nothing like what it was in high school. We march and play old style songs that frankly are not that fun to play. This is all just my opinion, but I have made great friends being in this company and there is a comraderie...
