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.

we were all petrified, felt totally under qualified and did as much as we could do to fill the perceived skill gap.

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.

a little performance pressure isn't always a bad thing
