ECON 709
Quality 5/5Difficulty 2/5
Very good! You can tell he's new; there were myriad typos in his lecture notes, and the homework problems were very easy. But those lecture notes were great nonetheless! Thorough, easy to follow, with numerous helpful example problems. Feel like I learned a lot from him.
