Not a good teacher at all. As other say on top, he just reads his notes and rewrites some stuff on the board. I saw no point of attending class. However, he does care for his students that he knows who comes to class or not. He always talks in condescending tone and his answer doesn't even help for student to understand the stuff. Don't expect to learn anything in his class. However, one good news is that he lets his TA write his exam. If you get a good TA, the exam will be piece of cake.
Fall 2021 - DO NOT TAKE THIS CLASS with Amar!!!!!!!!!!!!! 105D material is inherently difficult to capture, but Amar makes it even more difficult by not engage the material clearly. He barely know technology, including writing on surface / iPad, which makes taking a class with him a terrible experience. He talks really slowly and without a focus on what is important, he goes everywhere. The homework is A LOT and was BARELY RELATED to the material covered in class. Half of the equations used on homework does not even appear in class lectures, nor was covered by class examples, so you have to read tedious textbook for answers. You will take roughly 8 hours per homework to finish them. The exams are tricky and he is ALWAYS AMBIGUOUS about what is covered for each exam (Quote: "covers everything"). This is especially terrible when the homework and the lectures are NOT the same thing AT ALL!!! He WILL attempt to trick you with something never taught in class.
Winter 2020 - If you have to take this class for credit/grade, then you have to. If you want to learn the material, take another professor. Very confusing lectures that more than half the class stopped attending after the midterm. He gives hints for the midterm and final in his lectures, though, so you have to attend if you want a good grade. A nice person. Not an engaging or inspiring professor. After taking this class, I became disinterested in further study of heat transfer. Before taking this class, I was very interested in it.
Winter 2022 - This is my most enjoyable course at UCLA. Professor Hu is a great lecturer who is very knowledgeable and obviously concerned with our learning of the course materials. His lectures are very clear, efficient, and have a good balance between concepts and examples. I feel like I learned a lot from the class. I also like the small quizzes which helped me stay on top of the contents. Final exam shouldn't be an issue as long as you practice the homework. 105D can be a difficult engineering course otherwise, but this fantastic professor made it very easy.
Professor Ju does an excellent job of teaching his material. He made the entire course lecture into a pdf file for you to follow. While the material of 105D may not come as easily as material of other courses, he really does cover all the material in a very concise and organized manner. He really believes in thinking as opposed to plugging and chugging, and thus is a fan of derivations in his tests. The problems he gives are good. i.e. slightly challenging, but very "core". In lecture, sitting in your seat, he seems like the nicest guy. When you ask him a question, however, he cam make you feel pretty stupid, and kind of don't feel like asking him any further questions. But thicken your skin, and ask what you need to know. He makes himself very available, despite all that, and will answer your question thoroughly, provided he deems it not too basic and something you should have learned from other classes. Overall, great professor. You learn a ton from his lectures, he puts a lot of effort into organizing his lectures, and they are effective. His education philosophy is good, and you come out learning something worthwhile.
Spring 2022 - Lavine is probably one of the best professors at UCLA. Spring 2022 was the first quarter was the first one where she taught in person again, and while I had some complaints about how the class was structured, I would highly recommend it. The grade distribution was as follows: 55% weekly quizzes, 35% final, 5% homework, and 5% "extra". The homework started off easy but got progressively more difficult and time-consuming as the quarter continued. Regardless, you learn a lot from doing the homework and they're great preparation for exams, so despite being such a small percentage of the overall grade, I highly recommend you do them. Quizzes were straightforward, but difficult. They're open everything except collaboration with others. Do the homework and you will be fine. The final exam was slightly easier than the quizzes in my opinion. Her lectures are very clear and succinct, albeit they don't give you everything you need to know to do the homework, just the major concepts. You would need to read some of the examples in the textbook to do them confidently. Discussions were basically useless because the TAs go over problems that they release the solutions for; I used these discussion worksheets as practice for the weekly quizzes and found that to be a much better use of my time. In addition, Lavine structured her class as a "flipped classroom", where lectures were posted online but we would have to show up on Mondays for an in-class activity and Wednesdays for a weekly quiz. Personally, I despise this style of teaching because you spend so much more time in "class" than with just a traditional classroom. It may work for some people, just not for me. Part of class is allocated for office hours. Every time I was there, Lavine was extremely friendly and very eager to help me understand. She told me enough to help me work out a roadmap for the homework problems without telling me exactly how to do it, which I appreciated. Overall, you won't go wrong with Lavine, and when she decides to do live lectures again, I think that she'll be the best 105D you could have.
Professor Marner is the best professor that MAE has to offer. No question about it. He has a fantastic lecture style, a high level of organization and straight forwardness, and he involves the students in his lectures through his charismatic personality and humor. Don't graduate from UCLA MAE without taking this guy at least once. That being said, students considering taking his class should be aware that a high workload will be the norm. I also took him for MAE 133A, were there is a project which takes up a lot of time. During this time in the course the homework piled up sometimes even up to two homework assignments per week in addition to an approaching project deadline. Students should also not expect to pick their own groups; Marner wishes to make the class like industry so the TA's pick the groups according to a skills questionnaire. Great professor, great man...take his class at least once.
