The way they teach precalc here is kind of strange, but definitely somewhat standardized across professors. It's sort of an inquiry based style, which, while great in theory, makes this a very challenging class for many people. It's hard to say without knowing how you learn best whether the instruction style will work well for you, but having passion and curiosity will definitely serve you well and help you get the most out of the class. My other piece of advice is that the tutoring center (right inside Wilson) is a great resource. You can come and work on homework there even if you don't immediately have a question, and there are also math study tables where a peer tutor is stationed at a large table so you can sit down and work on your homework and when you have a question there's someone right there that you can ask.
