I 100% recommend taking this class with Dr. Tung! He explains concepts with great clarity and even showcases fascinating demos that really help to apply concepts learned in class. The format during the virtual setting was also very reasonable, with lecture attendance not being mandatory and all the hw due at the end of the quarter(though definitely don't start at the last minute). I found rotational motion(last topic) to be the most difficult component, so definitely put extra attention into practicing the material.

Best professor out there. Take his class if you can. He seems to really enjoy it, cares about students, and engages with them. He also does awesome demonstrations and he has the type of voice and enthusiasm of Neil deGrasse Tyson.

He did his virtual lectures through YouTube livestreams, which actually worked REALLY well, and he used TopHat to keep us engaged and to make sure we understood.

Lectures were entertaining and helpful. Tests were very fair. There was also plenty of extra credit.

Basically, take his class. I have nothing negative to say. Great professor.

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!

Dr. Tung is a really funny guy. He really tries to make lectures fun and engaging with fun demos and random jokes. His exams were a little annoying for me because they were all theoretical with no numbers but I got used to them after a while. They aren't super challenging but he has no practice problems that are like his exam questions. He uses slides but they aren't really helpful so you have to go to lecture to get the actual notes. He gave a LOT of extra credit this quarter, I don't know if he does that for every quarter but attending class was extra credit and doing all of the launchpad problems were extra credit. Two midterms and a final. Labs were graded on completion this quarter which was great because they were hard to do at home vs in person. Overall, I can't say I loved the class but it definitely wasn't as bad as the other reviews made me believe before taking the class.

I found this quarter to be a wreck. He crammed 100+ students into a lecture hall for the midterm where everyone needed their laptop for KUDU and it was just a mess. His lectures weren't helpful, all he did was demonstrations instead of actually applying the equations to problems. Tests were so challenging.

Background on where I approached this class with: apprehensive yet excited to see if I would like physics, and I have adhd.These reviews made me feel like even though I had no previous experience in Physics, this class was tailored to life science students like me who don't really have a physics mindset or background and wanted to dip their toes in. I was extremely wrong. This class made me depressed from weeks 4-10. I poured around 20 hours a week into this class, blood, sweat, and tears, but it still was not enough. I tried my damnest, had 3 engineering friends help me with homework, and I still got a C-. He is a decent lecturer, and I can tell he's knowledgeable. The homework is hard, but forgiving (you only have to complete 65% of all assigned work, and its online so you get unlimited attempts and sometimes hints, which I appreciated). The labs stressed me out so much, my TA was cool to talk to but a hardass on grading, but he has no control over that. The workload is pretty rough, not because its so much content, but because the content is extremely challenging. We had homework problems on Mastering Physics where you get unlimited attempts at the questions and only have to complete 65% of the total assigned homework problems for full homework grade, which I appreciated, most of these chapters had no more than 30 questions. The majority of the grades are the tests. I went to every lecture, every discussion, and every lab, rewatched lectures, studied homework problems with my generous engineering friends, and got a 51/100 on the first midterm. He does not curve to the benefit of students (or at all). His testing format is generous, but to be honest, the only acceptable format for free-response tests during COVID. A pdf is released and we have 24 hours to do it. We have 4 midterms throughout the quarter, which I also appreciate this format. Professor claimed that these tests were meant to be completed in an hour, every single midterm I spent a minimum of 10 hours on. Worked from when it was released (around 5) until I went to bed around 11-12, and then got up in the morning and worked on it until my brain was fried and I couldn't bear to look at it any longer. You know if you struggle with math or chemistry or physics, and you will struggle with this class. I passed with this C- by a miracle. Overall, the professor is generous and forgiving on assignment submission formats but the content is absolutely brutal. My mental health and daily life have improved since I no longer take this class. Professor, if you're reading this, make the content easier. It is ridiculous what we are tested on and what we are expected to know as life science students to an introductory physics course. Sincerely, someone who tried her hardest and barely succeeded.

TLDR: if you want a really high-quality, interesting physics class, and a professor who truly cares, but you don’t mind getting a lower grade, take this class.

I got As and A-‘s in the other physics 1 series classes, so I was pretty surprised to receive this grade. In general, Nathan Tung is very kind and cares deeply about student learning. His lectures are beyond entertaining, and I don’t even like physics that much. However, I felt this class was not very forgiving. None of the midterms were dropped, the TAs were not helpful at all, and the questions on the exams felt sort of unpredictable. However, there was a chance to get 3% extra credit which was nice. Furthermore, I cannot emphasize what a wonderful lecturer and kind professor Tung was. Overall, I enjoyed this class the most out of all my physics classes, despite getting the worst grade in it. (He did tell us in the beginning that he would try to keep the class average gpa pretty low as the physics department was requiring it, which kind of sucks.)

Professor Tung is a great lecturer and is very clear in his explanations. He also adapted very well to remote learning, probably the best I've seen out of any professor so far. Everything in his class was done on Kudu including the midterms. I think they got progressively longer and also more difficult, but they were still very reasonable. Tung also gave a lot of extra credit and hints for the midterms throughout his lectures.
The labs in this class were sometimes frustrating because it is taught like a separate course. Sometimes labs do not line up with lecture which can make it difficult to get prelab questions correct. The tracker program used in lab was a bit slow for me so it took me a long time to complete the labs at first, but with more practice I got the hang of it.
Overall, this course with Tung is not too difficult and I would recommend choosing him as a professor if you can.

Professor Tung is by far the worst professor I have ever had at UCLA. I have zero respect for how he teaches his class and I strongly advise against taking this class with him. He spends all of lecture going over pointless derivations of the equations and rambling on about convoluded concepts somewhat related to physics. He provides little, if any, examples that honestly have very little to do with his test questions, he provides no practice problems other than mastering which he even said were not reflective of the exams, and he provides no practice tests. His instructions for studying for the test were to "learn physics" and not just "study for his tests" and I'm sorry but that is complete bull. The average of the first test was 50% which according to him was his goal. The last problem on the test was worth 20 of the 40 points and no one had ever seen anything like it, which was his intention. Following the huge backlash of the 1st midterm, he tried to improve but did so sparingly. He held a review session for the midterm and it was surprisingly helpful however the average was still pretty low at a 63%. He is very condescending when speaking about grades in that he said in order to get an A you should be able to do problems you've never seen before just like him with no mistakes which is completely unreasonable considering he has a PhD in physics and none of us are even physics majors. All in all he sucks as a professor and I genuinely hope he drastically changes or never teaches again because I wouldn't want anyone to go through the torture and hell that is his class.

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
