Bus Calc will make you want to cry, but Dr. Vaughn will try to make it as bearable as possible. I HIGHLY recommend attending lecture and lab on a regular basis. Unless you're a math whiz, you will need to study your butt off if you want to do well in this class. My main complaint about this course is that the quiz and test questions were generally harder than the problems the instructor taught in class, which I found unfair. Only buy access to the homework... DO NOT buy the book; it didn't help me at all. Dr. Vaughn's colorful personality and Email Bag breaks make the class more enjoyable, so take her if you have to take this course!
