'''Kirby's section''': If you are not good at math, this class will be hard. But if you have a sound grasp of addition, subtraction, multiplication, and occasionally division, and if you have a sort of understanding of how math works, this class is easy. You don't need to do any reading to do the course, which is good since the texts and reading assignments are really dense. Classes are small, so the professor will notice if you are not there.
