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.

I usually don't recommend a professor, but I believe Professor Hu is among the best that I have met at UCLA. His lectures are always very well organized. For 105D, it has many different topics but Prof Hu can explain everything clearly and make it easy for us to learn. I actually have learned a lot from this class.

Yongjie is really a mixed bag. On one hand, he really cares about his students, and this was reflected in him reaching out to students throughout the quarter to check in on their progress and whatnot. That being said, he is super disorganised as a professor. He only decided in Week 6 that we would have weekly quizzes instead of midterms, and that the quizzes would be 55% of the grade. He also showed recordings of old lectures during class rather than teaching live himself. It's also Wednesday Week 1 of Spring quarter, and he still has not uploaded our grades. He's a nice guy, but comes across as lazy and disorganised, and his teaching style is meh. He's not horrible if there's no better options available, but be prepared for a bumpy ride.

This is one of the more difficult engineering classes I have taken so far, but thankfully the professor is always willing to help and truly goes the extra mile. He set aside a fifteen minute block for every student to meet with him towards the end of the course for questions and feedback, which is a lot of time if you add up all the students. The only issues I really had was that the class was mostly asynchronous this quarter, but the professor did the best he could in the situation. Would definitely recommend!
