Highly recommend Master Tung. Great lectures, fair exams. We had 4 shorter midterms instead of 2 midterms and a final, which I liked since we finished the last midterm done before finals week. His demos were definitely the highlight of this class though!

Dr Tung is a very clear lecturer, prerecorded so many cool demos for us to watch in class, and gave us extra credit for completing >65% of the homework. No surprises on the midterms, although the free response parts are slightly harder than lecture examples, it's still very reasonable. Definitely recommend his class!

Professor was fantastic. Really thorough with his lectures and even provides a large list of notes that can help you study. You are given mastering physics to do throughout the quarter, with one due date at the end of the quarter. Midterms were very fair. There was no final (only 4 midterms). I would highly recommend Tung for any physics class you may take in the future!

Professor Tung is wonderful! As someone who had zero physics experience prior to this course, Professor Tung did a great job of easing into the material and making concepts feel as intuitive as possible. This quarter he offered up to 5% extra credit on our final grade (!!) which could be earned by completing extra homework problems and in class participation. The amount of effort he puts into making class engaging shows how much he really cares about his students-- even though he has no idea what any of us look like, as he likes to joke. 10/10 recommend!!!

Professor Tung is one of the best professors I've had at UCLA so far. This is my 3rd time taking a mechanics class, and I wish Professor Tung had been the first person to teach me physics. He makes the subject material intuitive, he really cares about how his class impacts his students, and his enthusiasm makes a typically tough subject totally bearable. If UCLA doesn't hold onto this guy for as long as possible they're out of their minds. In conclusion, if you have the chance to take Professor Tung's class, there is basically no reason why you shouldn't go with him.

I love Professor Tung! Take his class if you have the chance; he's a really great person and super passionate about physics.

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

Dr. Nathan Tung is by far one of the best professors at UCLA. He is engaging, full of life and very kind and understanding. Though I had him online for 1A his interactive videos and demos made it worth it to attend live lecture.

The best professor at UCLA so far in my experience! As someone who miserably failed AP Physics back in high school, I dreaded having to take this class. However, Tung was able to teach us everything so clearly and his resources are great. He also knows how to use technology well, making it very neat and convenient. The workload could be a bit heavy, but it's definitely something you want to complete since they are a great study tool for the exams. Overall the class is super organized and Tung is super reasonable with everything. I truly learned a lot and actually started liking physics after this class.

He is a good lecturer. He gives massive homework chunks that are all due at the end of the quarter so it's easy to get behind on those but if you do more that 65% everything past is partial credit.

His midterms are 24 open book, BUT they are very hard do not be fooled. He is very big on cheating so just don't do it or else you screw yourself and everyone else over. He also gives a form of clicker questions where they are used for extra credit.

Overall, he sets you up for success but the class is still very challenging nonetheless. Also contact me if you want my notes for this class **********) for a low price (even if you don't take the class with Tung, friends in other classes found them useful). Good luck!
