Not bad; not great either. The class was typically big (200+, five TAs), and her lectures weren't the most interesting. On the other hand, she seemed to have a good grasp of the material, and her lectures were well-organized. The textbook is also very clear and well-written. On the whole, if you are interested in econ, this isn't a bad way to start. One note: there is a weekly discussion section which all students must register for; I found it to be virtually useless, and there isn't an attendance requirement.
