Winter 2021 - I loved 170E with Professor Tyler – he was a really good teacher, taught a lot, and was really helpful during office hours. There's a good amount of homework, but since we were virtual the midterms and final weren't bad. Class seems to be one of the easier math classes, but also one that's pretty interesting as well, and Tyler is a great teacher for this class.

Spring 2025 - Butson does a great job of making the homework challenging but not impossible. I always felt as though I was thinking when attempting his HW, unlike lower division math classes, where the problems are just rinse/repeat. He's always very helpful and kind in office hours; whenever I was uncertain about a question, I never had a problem asking for his help. I will say the second midterm exam was a little more difficult than anyone anticipated, he's really looking to get you to think beyond just a simple plug/chug formulaic approach to math. Final was very fair, all the questions were questions he went over in class, to some degree. Some were even from the second midterm. Overall, would very much recommend this prof but he probably is on the harder side of 170E professors.

Fall 2020 - This professor was the most unclear and unfair professor. I don't understand why he was even able to be teaching and don't believe he should continue. When I first started the class, I thought he was a really cool math professors with lots of icebreakers and fun games to help understand concepts. However, as the class went on it seemed to me that he really was playing mind games on the whole class. He would make typos on lectures and then frame it as if he did it on purpose, giving people bonus points left and right for what felt like complete favoritism. For our second midterm, he gave some of the class the ENTIRE midterm with word for word questions that COMPLETELY ruined the curve. The first midterm was fair and those who worked hard actually did better but since you were able to take the midterm with the higher score almost everyone got 100% on that midterm. Not to mention, he would tell us to ignore certain material that he said wouldn't be tested which then showed up on exams! For the final, there were many rumors that he gave people in office hours the questions that would be on the final. This class was extremely corrupt, as I had an A in the class up until the terrible and impossible final that was given. I am extremely upset with the way this class had ended and definitely wouldn't recommend taking his class. I have even reported this to the math department and I am very disappointed that no action was taken further.
