Not the worst class if you understood microeconomics and calculus to a degree. Textbook isn't mandatory, but I found the practice problems in the textbook helped a lot when I was studying for tests and exams.

Formula sheets are so helpful, and the practice problems Carolina has for tutorials are very similar to the types of questions that are on quizzes/exams.

Carolina is one of the best econ profs I've had. Her classes can be a little heavy on the content, but the detail does help.
