This class got screwed over. Everything's interrupting them this week, so the final got moved up three days with very short notice. It cut down on the time when we explicitly reviewed as a class, but after all the talks about needing to prepare, I'm lacking sympathy. If you have to stay back from next week's field trip to a theme park (that was just announced last week) in order to really prepare and learn the material, so be it.
Stop worrying. Or, if you're going to worry, do so productively.
