so this is a class where you're not really going to learn anything. villanueva is a nice guy but his lectures are so disorganized and tbh I didn't even go to lectures 6/10 weeks. discussion sections are mandatory attendance and it's just 2 groups presenting a research paper each week but tbh nobody even paid attention. you have a quiz every week but it's really easy since it's open note and it's 4 questions in like an hour (at least that's how our TA in F25 did it). no other hw or assignments except for the group presentation you have to do one time during the quarter.
the lectures are not great and honestly I didn't even know what was happening 95% of the time. the class is stressful for like the few days before the midterm and final because you have to basically learn everything and there's no recordings, so you're really just relying on the slides which are also not great. but villanueva lets you use a cheat sheet so everyone would just write down all the info on there and the exams we had were not that hard and they were like 20 questions (the exams were only like 24 points total each for midterm and final). the main way I knew what to study was because of my TA Aneesh whose final review sessions were literally the GOAT. TLDR I'd take this class again but idk how much the structure of the class changes from year to year so ymmv. just be warned though if you're like most people you're just gonna feel like you have no idea what's going on for most of the quarter

I wanted to like this module but I was quite disappointed by Prof. Villanueva's teaching style. First off, his slides are terribly unorganized with either no text or a mountain of text with no way to know what was important. Continuing this, for an unknown reason he would post two different versions of the slides and sometimes the slides in lecture would be just one or a mix of both decks. He spoke... so... slowly and asked so many questions to the audience with 30 seconds of silence that it was extremely disengaging. I gave up attending lecture when it became clear that I could never remain focused or understand in class. And it wasn't just me. By the end of the module, maybe 1/4 of the class was showing up and even looking around I would see people falling asleep. My method of survival relied on watching the lectures at 2x speed and going to discussion since the TAs were actually able to properly organize the material with what we needed to know. His test was easy enough though, just memorize and regurgitate like the rest of Phy Sci. If you've made it this far, you'll need to take this professor and this module anyway, just don't have high hopes for his teaching style and save your time by not going to lecture.

I honestly cannot remember much about Villanueva, he seemed forgettable. Nothing struck me as bad or good. His lectures were meh, and his exam seems decently easy/manageable. He seemed to be less enthusiastic about teaching as compared to quijada and certainly when compared with Correa.
