This professor was unflinching during the pandemic in his insistence about the final. He was highly unhelpful throughout the entire quarter. His class was extremely difficult, made even more so by his horrible communication.

Prof. Tornell is probably my favorite Econ professor so far. He's really kind and helpful, and you can tell that he cares a lot about the content and his students. Because of the coronavirus, the final was optional for us, so I opted out. However, I can talk about the midterm. TBH it was pretty tricky, but if you actually understand the content and aren't just cramming, you should do well. There isn't even a lot of content to learn; he covers like 8 scanty slides per class. His homework can be tricky sometimes as well, but you get a 100% for just turning it in.
I really liked this class. I feel like I learned lots of valuable real life knowledge and it forced me to keep up with economic news. I loved that we focused more on real-life applications than just theory. That's pretty rare for an Econ class.
Negatives: he teaches really slowly. It's p. annoying in the first few lectures but you get used to it, and it's kind of great because there's less content to study lol. There were some stuff on the first few homework assignments that were never covered in class. That was frustrating. The TAs NEVER respond to emails. Don't waste your time. The professor might respond if he's in a good mood.
