This class is tough for sure, but don't let all the hype intimidate you. You can get through it if you're disciplined with your study habits, do lots of practice problems, and do the reading. You'll use parts of the 3131 material in later classes (and on the FAR section of the CPA exam), so it's better to learn it as well as you can now. There's usually some kind of curve at the end since the class is mandatory for ACG majors, so you may still have a chance at making it if you end with a high C.
