Econ is just a dry subject, so I can't really blame Convery for this class being terrible--I don't really know how you can teach Econ with pizzazz or make it seem engaging and fascinating. Convery is a very nice guy and more than willing to help you--he met with me outside of class, always emailed me back, and hooked me up with a tutor. But yeah--I had to get a tutor for this class, because I was doing that badly.
The lectures are dry and dull, and all of his slides go up online so you don't really have to go to class anyway. I think I would have done better if I had just worked out of the textbook and done example problems from there, because his slides don't really help you learn how to do the mathematical problems you later see on his exams. Convery is great about providing practice problems--he puts up problem sets for every chapter that is covered, as well as provides sample midterms and finals for you to work on (all with answers included). He holds review sessions before each test--which were of no use to me, but maybe some people got more out of them. It's really not Convery that makes this class bad--econ just sucks tbh.
Anyway, class is 25% midterm 1, 25% midterm 2, 50% final. He curves the class at the end of the quarter, so here's to hoping I end up on the right side of the curve because I could go one way or another. If possible, I would recommend you check out one of Convery's lectures and one of Sproul's and then decide whose class to take depending on who seems more engaging. I wish I had done that, maybe Sproul's style would have worked better for me.

If I had the chance to go back and re-plan my schedule, I would not have taken Econ with Patrick Convery. I think that the material that was taught was interesting but his lectures are extremely boring (and pointless because he puts the lectures up online) and he just reads off the slides. There is no homework in his class but there are suggested reading assignments that no one really does (but I found them helpful because Convery was not helpful at all). There are 2 midterms each worth 25% of your grade and the final that's worth 50% of your grade. I didn't do that well on the fist midterm and when I went to go see him to talk about what I did wrong and to go over the concepts, he didn't really answer my questions and I found the other meetings I had with him were unhelpful. The TA's for this quarter were all very unhelpful and the only recommendations that Convery gave to me was to get a tutor (who cost $70/hour). He also purposefully said that he would make the second midterm and final harder so that there was a larger distribution in terms of grades amongst the class.

I would suggest not to take Econ 1 with Convery and spare yourself the tears and stress.
