Let me start off by saying that Lancaster is an extremely genuine and caring professor. It's evident that he cares deeply about the success of his students, and tries to engage with everyone both before lecture and at office hours. I personally didn't find lectures helpful or necessary (he talks VERY slowly) so I didn't go to most of them; discussion sections were sufficient for me. He basically reads off the Pearson slides in lecture (which themselves give way too much info) so it's easier to just take notes on your own time on what you actually need to know since everything is posted to CCLE. There were no posted practice exam problems for either of the two midterms, but he does go over some in lecture and did post a few for the final which was very helpful. Exams themselves were pretty straightforward given that you studied for them.

Professor Lancaster is a very kind person. I'm really not a fan of the asynchronous learning structure, but the good thing is his lectures are so slow you can comfortably watch them on 2x speed so I watched all three lectures for the week in one sitting. Tests are 35 mins but he pretty much gives you an identical test for practice so that's all you need to study to do well. The class is not bad and Prof is very sweet. My main problem with it is that office hours often had 100+ students so it would be very hard to get any one on one help with the professor. Other than that, it's very doable.

This guy is not good.

This class was absolutely miserable. I believe Professor Lancaster failed to realize that this is an introductory class and completely ruined my perception of physics. Homework was annoying to complete due to the penalty and the large amount assigned. Exams were extremely difficult to retain. Time limit of 35 minutes was the worst ever. Office hours weren't even during the time stated in myucla. It failed to say that this is an asynchronous class but I think he's fixed that for next quarter. Although I passed this class, it did not come easy at all. I was stressed the entire time. Stay away from this professor's class if you can.

I was just 1 point away from an A- and this guy decides not to curve the class like he promised.
Not to mention he doesn't give equation sheets for exams when all other professors do. Lancaster sucks, that's all. The fact that he's still teaching after all these bad reviews proves UCLA doesn't care about its students and god is dead.

I was forced to take this class to declare my major. Almost all the reviews I read for Lancaster were negative and they were right. This class was pretty difficult in terms of the tests Lancaster gave us. The first midterm was fair and tested material that he went over in class. The average was a 91% which is the highest average I've ever seen for a midterm. However, the second midterm was insane. Virtually nothing that he taught was on the test. He included difficult concepts from 5A that he didn't even go over in class. The average was so bad that he allowed us to make test corrections that would bump up our test score by 12 points. The average with the test corrections was an 81%. The Final was extremely fair. My TA basically went over all the topics that would be on the test. I studied these topics and got a 91%. The average for the final was 82.45%. For the final there was an essay question, but it was straightforward. You had to explain a concept and draw a diagram. One piece of advice for this class is to really go over and check how the TAs graded your test. In both midterms my TA took off points when I got the answer correct. In the case of the first midterm he took of 10 points even when I got the question correct. I submitted a regrade request and he gave me back the point. So just be sure to check your test to see if they made any grading mistakes! Overall this class was challenging. The workload wasn't too bad since we only had about 20 questions due each week along with a discussion question. However, the test were graded harshly and the content of the tests were unpredictable.

Professor Lancaster is just dry as a lecturer, but he explains concepts adequately and the exams are fairly straightforward. This was the first quarter back in person, and reading the reviews from the online quarters he sounded terrible. In person he is not at all like he apparently was for online. You could tell he wanted us to succeed. Lecture attendance isn't mandatory (though I would recommend going because he sometimes adds important information that isn't on the slides). The homework system is fairly lenient (you get about 6 tries and only lose 3% on each problem that you get wrong after each try). The exams have one or two problems with about 10-15 intermediate problems that somewhat guide you through the overall problem.

Easiest class ever. We had mastering physics, discussion problems, labs, 2 midterms, and a final. Since we were online, discussion problems were all due on Sunday night regardless of what day your original discussion section was. The TA's gave us one problem each week and they were graded on completion. As for the labs, the physics dept created weekly labs that you could do with household items. The post-lab assignments would ask you for pictures of your set up and some easy calculations and questions. The pre-labs literally just asked for a picture to ensure that you had all the items needed to perform the lab (often times, just a tape measurer or something). The midterm were extremely easy (class average was in the high 90s, maybe even 100 lol) and the final ended up being optional. Lectures were pre-recorded and he would upload them all at the beginning of the week. Not gonna lie, he is a boring lecturer and after week 3 I stopped watching them. He just goes over each slide so you can just go back later and skim through them for necessary formulas.

literally did the discussion homework on the cardboard part of my notebook and still got an A+

10/10 easiest physics class i've taken, would take again (during covid)

This is just my personal experience with this class, I cannot speak for everyone that took this class this quarter. My experience with professor Lancaster was not bad at all. I found the structure of the class pretty easy to follow. I did all the homework for the week the weekend it was due and it did not take that long. I watched all the lectures at 2x speed and took notes on the slides. I had a great TA who went over all the discussion problems step by step. All I did to review for midterms and the final was go over the slides and make a summary sheet and go over the practice problem he gives out the week before the exams. The exams were basically the EXACT same if not slightly easier than the practice problems. However, I did have a quiet place to work through the exams and I live in LA so the time constraint was not as hard on me. I usually work out problems fairly slowly and I was able to finish every exam with a little bit of time to spare. Note: I did not have time to check answers but I took physics in high school and that helped tremendously. I also have reliable internet. Overall what I would say about this class is it is fairly easy IF you do not need accommodations. That, however, is a big IF and I believe under different circumstances I would not have done as well. So I would say take these reviews with a grain of salt and think about your own situation because it is true that professor Lancaster is not very accommodating but this has been one of the easier classes for me that I have taken so far at UCLA.

PS Tung's class got a lot of extra credit and he gave 24 hr exams and a lot of my friends said he was a great teacher.
