when i was in grad school all the faculty were off doing startups and they had the grad students teaching the undergrads because they were never around.<p>we were all petrified, felt totally under qualified and did as much as we could do to fill the perceived skill gap.<p>i think without an exception we excelled. the courses were harder, graded better, got better student feedback, covered a lot more material and engendered a reciprocal student response that the distracted and jaded profs never got.<p>a little performance pressure isn't always a bad thing
