Professor Tung is an amazing professor who was very accommodating to us during the pandemic. He gave detailed reviews before his exams and was very lenient while describing everything so well :) He cares so much for his students and always went the extra mile to make sure everyone understood (he answered all the questions in the chat and risked getting injured to give us physics demonstrations). He has detailed notes for his whole course (literally like a second textbook). During the pandemic, he had 24 hour exams and offered extra credit questions to take roll. Homework only needed to be done to 65% and if you did 100% you got a little bit of extra credit. Coming in with no background physics knowledge, he made the subject approachable. Thank you Dr. Tung!

Professor Tung is definitely beyond my expectations. The 4 midterms each make up 22.5% of the grade, while the homework is 25% and the discussion worksheet is 5%. For the homework, you only need to complete 65% to receive full credits. Anything beyond that is extra credit. You can also receive extra credit points by answering tophat questions during live lectures for both completion and correctness, and you can receive up to 5% of extra credit in total. That is a huge amount especially given that the exams are neither cumulative nor hard (though very conceptual).
Tung's lectures are clear and well-paced. They are on youtube, and he responds to the chats quickly. There are more than enough extra credit points in homework to get the 5%, so it's perfectly fine if you do not want to pay for Tophat. The slides on Tophat are not important for the class, as you can find the summary of basic concepts in Tung's notes. The notes are really nicely written and compiled.
Homework does not penalize you at all for giving wrong answers, so it's a good way to practice without any pressure. Just make sure you practice the conceptual questions without numbers, because there won't be any numbers on the midterms.
Tung's class definitely made my winter quarter more enjoyable. I cannot expect anything more from this class. 11/10

Don't listen to these reviews. It's just a bunch of whiny stem kids. The class and professor are fair, and I am sure everyone will eat their words when final grades come out. He's trying his best and it's clearly evident, and to put yourself in his shoes would give you a lot of perspective on how good of a teacher he is trying to be. Emphasis on teacher, as he cares about education and is going against the grain on just giving A's to everyone who think they deserve it, which is why he's experienced such a backlash from these entitled students who think that grades should be handed to them on a silver platter. Don't get me wrong, I still failed the first midterm like everyone else; I am not someone who's excelling and is on a high horse. To give him such bad ratings shows the disconnect between the value of education and the demand by stem students to be handed a good grade so they can move on and go to med school. These people seems to be missing the point about why they are in college... Every classmate I have spoken to has not blamed the professor as they can see him really trying and adjusting, and they all trust that he will be very fair in grades at the end. The students on bruin walk are NOT representative on how students feel in this class, don't let the whiners dissuade you from taking this professor, he is a good man and a great teacher with a lot of potential in the future.

Nathan Tung didn't prepare well enough for this class. Although this is his first time teaching his test were poorly worded and he continued having poorly worded tests all throughout the quarter. I would highly advise against taking this class with him if you want to learn. Not only did he want us to practice the questions on mastering physics, but they had no correlation with his tests. The only way to describe this class is chaotic. Every lecture he had a new experiment which was visually appealing however we're here to learn and to prove that we understand the material. It's impossible to do so when the tests don't reflect what we studied which was unguided. How were we supposed to study what we didn't know was going to be on the test.

As a 3rd year taking this class, I've never failed any course in my life until taking this class. To the people who said the class was easy, yes the class itself (concepts, ideas) are pretty easy, but the exams are the problem. Tung did not do a good job of emphasizing what was important takeaways for the course. The midterms and final were obviously physics related, but going to lecture, doing mastering physics, or reading the book will not help you. For Tungs exams, you either get it or you don't. I had several friends take the same course, and they all say the same thing-- they had no idea how to study for mt2 or the final because of how open ended Tungs approach to asking questions are. He stated himself multiple times that mastering physics will not help us answer his exam questions. I think as a person Tung is passionate, and wants us to learn which I appreciate, but his approach is all wrong. I originally failed this class, but he likely realized too many people failed his class and gave me a passing grade. Would not recommend taking this professor.

Professor Tung did not prepare us enough for the tests in this class and the materials covered in class were much too easy compared to the material tested. The first midterm was a complete shock to me as I had reviewed over the class material religiously and still could not do HALF of the test. The second midterm was a bit better due to the review session but it was still quite difficult to me, and a lot of the wording was just confusing for no reason. Lectures were generally not very engaging besides several experiments, and all the notes were done on the chalkboard. It was EXTREMELY difficult to see any of the notes past the fifth row from the front of the lecture hall and the material we did in class was usually pretty easy, like explanations of simple conceptual ideas or formulas. Professor Tung also did not give out any extra credit, even after the entire class was very upset over the first midterm. The only helpful thing from this class was the final exam review. I would strongly advise against taking this professor unless you already have a solid foundation in Physics knowledge.

I feel like many of the negative reviews are unwarranted. After the low scores on the first midterm, Tung did change things. Like others said, he hosted his own review sessions which were extremely helpful and told everything we needed to know for the exams.

I do agree that the Mastering Physics homework was useless. But, he provided “Nathan’s Notes” which supplemented the textbook and covered almost everything he talked about in lecture. These notes were super useful to me and prepared me well for the final.

The class is heavily concept based, so the examples provided in class weren’t exactly “examples” as we’d expected. However, he pulled most exam material directly from lecture. The second midterm and final were fair, in my opinion, given that he covered everything in class and review sessions.

This was professor Tung’s first quarter at UCLA and he was by far the worst professor I have ever had. He would spend all of lecture reviewing formulas and expect students to answer elaborate problems on exams. Not to mention, he provided no preparation for the exams and was absolutely a mess.

Honestly, dont listen to those bad reviews, those are the people that just rely on the lectures and dont take the time out of their day to commit and use other resources. While it is the professor's first quarter teaching the class, i believe he is doing well in it because i was able to score decently in both the first and second midterm. A huge part was due to his lectures and whatever i did not understand, i went home read the book, did practice problems, or i went onto khan academy. This guy teaches you on concepts, not pure numbers and formulas you have to memorize. Honestly, he is a good professor, those people complaining want everything given to them including an easy A.

I'm retaking this class with a different professor right now because I was unable to finish the first time due to personal issues. I'm coming back to say that, after taking this class with a different prof (Rombes), I think that the way Tung teaches makes the course a lot harder than it needs to be. His lectures were engaging for the most part, and he was good at explaining things clearly, but I think he tried to teach concepts in a way that was too in-depth for an intro physics course. There are a lot of things in my old notes from this course that haven't even been mentioned in the one I'm taking now because they're not necessary to understand the curriculum.

If you like physics and want a deep, integrated understanding of the different concepts in 5A, then this might be the professor for you. Otherwise, I found that other profs like Rombes make their courses a little more beginner friendly.
