Winter 2022 - If you're considering taking this class with Alwan, I wouldn't be discouraged by the negative bruinwalk rating. She isn't the most engaging lecturer, but will take time explain difficult concepts, and will stop lecture to clear up any misunderstanding that you may have. The pacing of the class is a bit odd, where the first half of class that covers material similar to 102 drags on a bit too much, and the latter half feels a little fast. However, I felt like there was still enough time to grasp the material. The homework assignments seem simple at first glance (usually three to four problems per week), but the problems are usually pretty thorough with multiple parts, so they will end up taking a good portion of time. I had Jinhan as my TA, and every week he would post discussion notes consisting of the answers of similar problems, which were especially helpful with difficult homework questions. This class is not very heavy on homework, and additional review of the textbook practice problems were helpful for exams. In terms of the exams, they were pretty fair. There was one midterm and one final. A good portion of the questions on there were related to the homework questions, but there were some parts that required some additional thinking. Paying attention to the examples she spends time going over on the lecture definitely helps. We were also allowed a sheet of written notes, which helped with all the different formulas. The exams definitely weren't easy, they weren't unreasonably difficult either. Overall, I'd recommend not being discouraged in taking this class with Alwan. There likely are better professors for 113, but there's no need to restructure your schedule to make that happen. You'll learn the concepts well, just that the overall curve might not be as generous as you would wish.

Daneshrad plays the game “I know but I won’t tell you.” Consequently, his lectures are totally useless. It seems that he instructs his TAs adopt the same philosophy (if it’s a philosophy at all, but let me be educated, you can use the most properly word to qualify this attitude). He repeats what is in the reader making an impressive rate of mistakes when he is not reading his notes. He does not provide any personal approach for understanding the topic is talking about. Conversely, he will confused you madly when his lack of understanding of this class (I mean EE13). There is a moment in which every good and excellent professor provides to student his insight about the course he is teaching that makes his lecture memorable and worthy to remember forever, and to attend. DO NOT EXPECT THAT FROM THIS ASSISTANT-PROFESSOR. If you enjoy his great English pronunciation, it’s fine, but he is an Electrical Engineering assistant professor, not a political sciences one. I don’t know what his problem is, but certainly, UCLA engineering school is going all the way down the hill with people like him. Midterm: Easy but tricky Final: 50% was the project. Overall quality: very low as teacher (From A to F, I would give him a D-) assistants were even worst

Winter 2019 - Honestly... she's probably the best you're going to get for 113. Her curve is set so that median is a high B+, pushing to an A-. But the way she runs her classes is problematic. Her examples and lecture notes are too simple, and are designed to teach you definitions and to present formulas to solve questions with (e.g. determining if a system is linear, TI, casual, stable). The homeworks and discussion sections are designed with similar principles, but much harder. Then you realize the goddamn midterms are EVEN HARDER, but on top of that, a large portion will usually involve proving some crazyass property and the questions related to homework and discussions make up maybe only 30% of the exam. And to nobody's surprise, the class got absolutely dumpstered. So on the final, the focus was on stuff similar to homework questions, which is good! But the test is now 36. FUCKING. PAGES. Just endless questions (i.e. endless torture). So that's already bad design. But on top of that, because of her grading scheme, and the fact that the midterm averages were so low and unrelated to the design of her final exam, it made me realize that I totally didn't need to even take any of the midterms. That's not a good outlook on the class, just fyi. Anyway she has an extra credit project. Do it lol.

Winter 2023 - Kadambi is pretty cool prof. Gives cool grad student vibes. His tests could be a bit confusing, but I thought he taught pretty well. His quizzes were stress-inducing and he seemed strangely attached to justifying their existence and use. Also loved his rant about how much money he has from selling his startup (in response to an anonymous student review saying he needs to touch grass and work in industry). We literally had to watch a recorded make-up lecture afterwards to cover the material because he spent like 40 minutes talking about how much money he made and how many patents he has which was hilarious.

Spring 2020 - Professor Lorenzelli is nice and professional. He provides well written (as in organization but maybe not in handwriting) notes. He would try his best to clarify things in class, and he can be easily accessed outside of class. Perhaps more importantly, he is a very kind human being, that he would try to accommodate everybody's needs and you could always talk to him if you need anything special (ddl extensions and etc).
