Spring 2019 - For 131BH. Best professor ever met. He cares about students’ experience and is definitely good at teaching. The workload is not as heavy as 131BH taught by other professors, but due to the nature of the class, you still need to spend a lot of time on the class. Take his classes whenever possible!!!
Winter 2022 - Dr. Madrid is very friendly, helpful, and generous with the office hours! The class is very hard, but if we attend the discussion and office hours regularly it helps a lot! Our TA Steven Truong is awesome as well. I suggest everyone who take 131B to go to Steven's website and review 131B materials since test-related concepts are on there. Tests are all online, hard, and require some creativity. There are 2 midterms (24h) and 1 Final (48h). Overall, Dr. Madrid makes this class a lot more tolerable!!
Spring 2018 - Good professor in my opinion. Would have him again for another class. He was very helpful, nice, and approachable in office hours. The class was mostly very difficult because real analysis is a very rigorous topic. As far as individual professors for this course go, I have heard of there existing (lol, a quantifier. math joke) worse professors for this course such that they give unreasonable homeworks. His homeworks were very reasonable yet challenging given the nature of the course. His two midterms (I'm writing this before the final) were doable but not necessarily easy. The questions just weren't what I predicted based on the the homeworks and course material but the questions would absolutely fall under the category of what you would consider fair game (so just be sure to study comprehensively as opposed to focusing on certain topics). The average for my class on the first midterm was actually very high, but he explained this was atypical as it was not as high last time he taught the course (a.k.a., my particular class was probably just smarter). I would not necessarily suggest taking him for lower division courses however; he is a very intelligent professor and his math skills manifest in his lectures to the extent that lower division students likely cannot keep up with him. Anyway, I really liked the course. Not a bad idea to take Manion.
