I really love this class! :) I thought that the material was super interesting, and I enjoyed learning about immunology! But this is class was, by far, the hardest class I've taken at UCLA. The lecture material is dense, I had to continually pause the recordings and rewind, which made the 1hr recordings take 3hrs to watch and take notes on. Professor Yang's lectures were especially difficult to watch- I had to watch them on max volume at 1x speed because I couldn't understand what she was saying with her accent. The recorded lectures had VERY POOR video quality ( the images and texts on slides were blurry) and VERY POOR audio quality and there were also no closed captions! My ears hurt after trying to watch every lecture and I would get so mad because I couldn't understand 75% of what Professor Yang was saying. Perhaps it will be better in person, but I found myself getting so frustrated because I could not understand her in the recordings at all. The exams are very fair though, just like the homework problems!

Lily Yang and Tim O'Sullivan co-teach this class and their new format is using flipped classroom learning. They each record lecture videos and expect you to watch them before class. Class time is converted into office hours and you can only ask questions from that day's lectures (meaning no going back to previous lectures). They do not hold additional OH outside of scheduled lecture times.
The lectures were very difficult to comprehend due to poor video quality and audio quality. At points, the video was incomprehensible and required a separate audio only file to be made. I felt that the lectures were also poorly organized. In other words, the professor jumped around a lot going over content and often repeated information covered previously, which made things confusing. I also felt that substituting lectures for office hours was inappropriate. The professor did not hold any additional office hours outside of the designated lecture times. The problem with this is that if students have questions outside of lectures or from different lectures, we cannot discuss that during “office hours” because they only discuss content from that day’s lecture. This makes their “office hours” very restrictive and not practical.
The midterm/final review sessions were also inadequate because they replaced “office hours.” The professors held the midterm review session on the same day as the midterm. During the final review session, 15 minutes were wasted because the professor wanted us to fill out the evaluation forms. This is not appropriate because it takes away the already limited time we have with the professor to review content. Furthermore, the practice quizzes in lecture do not nearly correlate with the difficulty and complexity of exam questions. I felt that the professor was not very engaging or enthusiastic about helping students
The pros of the class is there's only one midterm and one final (non-cumulative). Plus, the exams are open notes (I used a binder and focused on understanding the figures/mechanisms).
Overall, the class content is doable and reasonable. However, the poor execution and minimal teaching of course content makes this course difficult for students with little research experience. As one of the flagship courses for MIMG, I hoped for a stimulating and interesting class. Instead, the material felt dull and very basic. If you like asynchronous learning and self-studying, take this class with Yang/O'Sullivan and just take really good notes for the exams. If you want a class that's stimulating and engaging, take it with Zack.

This was a very hard class, but incredibly interesting. The lecture format could be improved so it is more engaging, but overall the flipped classroom format really helped get all my questions answered when I watched the lectures on time. They are also very generous graders. Dr. Yang is so knowledgeable about her material it is insane, so having the chance to ask questions and pick her brain was very valuable.
