Do not skip classes!! Everything is explained clearly if you're there and listening, but notes aren't normally put online, and when they are you only glean a little bit of an understanding. Showing up is super important, but if you do, you should be fine. Very math heavy and applying formulas that we're taught to situations. Essentially, if you put in the work and do studying on your own time the week leading up to a test, you'll be fine, but if you don't study or don't always show up, this'll be a rough course.
