Professor Kosenkova was a great professor for this class. Going to class, asking questions, putting in the time (10 hours per problem set), and going to discussion ensure that you get a lot out of this class. It has been a challenging course for me, and I expect to get around a B+, but the key to me has been asking questions and going to discussion section. I think if I'd attended more of the discussion sessions, I would have been able to get an A (but who wants to go to class late on a Thursday night). Anyways, I think this class is a good one for a strong foundation in econometrics if you want to do analytics or research in the future.
