Foundations of Geometry
Overall, not too bad. Has a really good sense of humor, which made the class period bearable. He is old, which means he has a lot of teaching experience, and it showed. He has a clear, concise way of explaining things, and there was hardly ever confusion about his explanations. He only gives one midterm, and the final is the other part of your grade. There is graded hw, but it doesn't factor into your grade unless you're borderline. He didn't have a textbook or even a syllabus for the class, but he printed out notes for each lecture. He is a straightforward, no nonsense professor, and I really enjoyed his class. I'm taking him again!
Spring 2020 - Honestly having Marco with this class this quarter was godsend. He was very considerate of all the situations going on with covid and protests. The class was interesting the material was all easy to understand. Putting those ideas into use to create proofs is difficult but getting through them makes you wonder why you hadn't before. We covered a lot of different geometries off the top of my head they were Euclidean, affine, inversive, and hyperbolic. Don't remember if there were more. Like any math class this class takes time. You need to know the theorem and the properties from each geometry. I think Marco did a good job of explaining throughout and was always willing to help regardless of your at home conditions :)
Mess can be a little awkward, but overall cares a lot about his students. I took him for 123 and 106. His teaching and lectures are hard to follow but he stresses proofs above all else, especially the ones he does in class. He is an extremely easy grader. If you get the proof right, or almost right, or if you're on the right track you'll get full credit, or mostly full credit on the midterm and final.
