Whatever you do, never correct a college professor, no matter how ridiculously wrong he is. It'll earn you an enemy for the rest of your time at school. A lot of profs are egomaniacs for some reason, and they don't like to be reminded that they aren't right about
everything.
Status and prestige are a big deal for those people.
