Taking this class online was extremely challenging for me. I do not know if it was the content in general or the actual teaching style, but I found it extremely difficult to keep up and understand. The class is made up of weekly homework assignments, two midterms, and a final. I found all of the tests hard to study for as they were in a sense cumulative and we were not given a study guide. I am typically good at math, but I think the online environment was not one that I thrived in. If you do take this class, both the TAs and teacher is accommodating, just make sure you stay on task and do not get behind on lecture. I got WAY too behind and it was too difficult to catch up.

I took this class online due to COVID. Overall, Prof. Moreno was super nice and cool. He was a clear and engaging lecturer and explained concepts thoroughly. Participation and homework were light. The weighting was 25% for each midterm, 30% for the final, 15% for homework (the lowest homework score was dropped), and 5% for participation, which was measured using Campuswire. It was easy to meet the threshold for points on Campuswire; you just ask and answer questions that other students post.

The TA section I attended with Ben Jarman was super helpful. He went over any difficult homework problems and explained confusing concepts clearly. Would recommend going to him if you have the chance.

The most difficult part of this course was the midterms and final. Given that it was online, the professor made the questions very conceptual and with little calculation problems. It was helpful to have 24 hours to figure out the problems. but the problems themselves were very tricky and required a thorough understanding of the concepts of the class, not just knowing how to solve the math problems.

Overall, the course was not too difficult, and I would recommend taking this course with Dr. Moreno if you are willing to put in the work to REALLY understand the concepts. Just be warned that the tests were hard, at least while school is online.

He was a reasonable professor. Would recommend. Participation was required on campuswire, but it was fairly easy to fufill.

Overall Professor Moreno was very fair and a good lecturer and if you know the material, you'll do well. The midterms and especially the final was difficult compared to the hw but with the 24-hour time limit, it was definitely doable. He also gave 5% for participation which was very easy to do on campuswire and let us drop one he as part of the hw grade. He also gave us 1% extra credit for doing his evaluation so that also helped boost people's grades. Overall would recommend Moreno for a relatively straightforward Math 31B experience.

Homework was fairly light and his lectures were pretty clear, but one thing I disliked was how hard his exams were -- a group of people cheated on the first midterm, so the second was exponentially harder than the first and tested us on material we never went over explicitly in lecture. It took me ages to figure out how to solve those questions because the wording of the question was also quite confusing, too! I emailed him about it and told him I was worried about the final because of how much I struggled on the midterm (I did actually score a little above average on that second midterm) and his response was...not great.

If you're taking his class in person I would probably recommend him because he is very patient in lecture and always happy to answer questions, plus you don't have to worry about having exams being extremely difficult to counteract cheating!

Even though I dropped the class for unrelated reasons, Dr. Moreno is the greatest professor I have ever had. In spite of clearly being a genius beyond our comprehension, his ability to simply complex concepts is unmatched. Further, he truly cares for his students and is extremely lenient towards them. He is arguably the greatest professor this school has produced, if you get the chance, take him
