One of the worst professors I've ever had. Takes simple ideas and complicates them beyond any sense of understanding. She goes way beyond the scope of the course material, rambles on a lot, and the exam questions were filled with all kinds of errors. If you are taking ECON1000, do not take it with this professor.

She has a lot of experience teaching economics elsewhere so her terminology is different than that of every other professor. She is also big on giving out trick questions; every test I took just felt like a series of traps. I got an A+ but my grade was definitely much lower before the bell curve.
