Regan is a cool guy, I like him a lot and he clearly cares about the welfare of his students, but fuck this class is hard. I'm a CS major, I don't care about physics, and I really don't want to spend the amount of time required to do well in this class on physics. It's probably a good take if you will do physics upper divs, but it's not for me.

This class for most of the quarter was quite difficult and had me questioning my major. There were two midterms, a final, and a bunch of homework. The homework was very doable and Regan would almost always extend the deadline. The midterms were difficult but overall I would say they were fair. The final was also fair in my opinion. Some tips for future people taking this class: 1) Don't freak out if you start off the quarter not knowing wtf is going on in the class. The first lecture petrified me and I didn't think it would get better from there, but it does. 2) KNOW THE HOMEWORK. It seems that Regan really liked pulling questions from the homework to put on the midterms/final. If you really know the homework and the ideas that were covered then you will do fine on the exams. 3) Don't freak out if you do poorly on the first (or maybe second) midterms. Since Regan curves, as long as you stay near the average you should do fine. I was below average by a lot on the first midterm, around average on the second midterm, but I crushed the final, so I ended up with an A-. For me, Regan's lectures weren't that helpful, but they were entertaining. I found myself mostly self-studying for the course. Overall, study the homework/textbook really hard and don't freak out and you should do fine.

Grading: I got an A without really understanding anything and get about the average on every midterm/final. Still very confused about that curve. The averages were around 55-65%.

Prof: Take Regan if you really understood 1B, if not, you're kind of screwed. You also have to understand the readings that were supposed to be done each week and took about ~2 hours each for me. He makes the assumption you know all that information going into lecture. Which is great if you do because then he teaches very well at that high conceptual level. If not, then you'll be in week 10 and see him write Maxwell's equations every lecture and still have no idea what they mean.

Regan: cool funny guy
tests: crazy hard
homework: ALOT
hbar: stupid human constant
don: enlightened
the curve: GNARLY

fr fr tho, prof is super dope, funny and knowledgeable. He teaches QM with his own twist, which was weird at first but later it kind of grows on you.

This class was extremely difficult I would recogmend not taking it with him. This class is also technically skippable. If you must take this class take it with a diffrent professor.
He is a great guy, funny, and lectures well. But his exams can be astronomically difficult.

Regan was very passionate about the content in the class which showed during lecture but lectures themselves weren’t helpful. Sometimes there would be a nugget of good information in one of the derivations which would help on a homework problem but the homework problems were mostly self taught. Don’t bother going to office hours, he can be really helpful when on track but most of the time it was just a hang out. The two midterms were nearly the same as the homework and the notecards were helpful. The final was brutal and the highest score was a 35%; it was not in any way similar to content we found in class. Overall my advice would be to read the chapters before you do th homework. Don’t be stressed by the first 3 weeks of the class, it’s supposed to be overwhelming. The last 3 weeks were a breeze because everything interconnected and the first 3 weeks finally made sense. I only got a B because I wrote an equation wrong on my notecard but otherwise I think I would have probably gotten an A- . I think beside the mishaps, Regan was pretty fair and reasonable.

Most difficult and stressful class I've ever taken, and it doesn't need to be, so avoid this professor if you can. Saddly he was a really entertaining lecturer, I actually enjoyed class, he also told jokes, always tried his best to answer questions, and held lots of office hours. But that doesnt make up for the fact that I thought I was gonna fail most of the quater. I walked out of both midterms and the final thinking I could have studied weeks more and not been able to get a 60%. The average grade on both midterms was around 50%, but if you stay around the average (I was below by a few percent both times) and turn in all your homework, you might be okay besides the anxiety and depression. I still don't understand how I got a B-, honestly, the curve must have been crazy. If you are a quick study, extemely knowledgable on all physics, and phenominal on creative problem solving, you might be one of the f***ers who can get an A, otherwise you're in for a wild ride.

Lectures: It's clear that he loves what he's teaching, and he'll bring in his own personal taste into things. If you're interested in physics, then it'll be awesome. If you just want to pass this class, this can feel a bit intimidating. He does a good job telling you what you need to know.

Homework: Reading the textbook is a must since his lectures sort of assumes you either already have some previous exposure to the topic or have read the textbook. Homework itself is of reasonably length, though sometimes the formulas required are in the textbook but are not mentioned in lecture.

Office Hour: Really nice and will talk to you about anything.

Exams: Quite challenging. The test questions are definitely complicated and a time crunch to think through and write down as much as you know. However, he curves fairly well.

Overall: If you enjoy lectures from someone who's really interested in Physics, then you'll like this class. You'll not only learn the course material but hear it talked about from the perspective of a physicist. However, be prepared to also put in the time because the content material is not easy tp master.

the goat. I have no idea wtf maxwells equations are but I still got an A. Like others, I am a stupid CS major who does not care whatsoever about physics, but I actually ended up being mildly interested after taking this class. If you do the homework, skim the textbook, watch lectures and try to understand how he goes from 1 step to the next (even if you don't understand the problem as a whole), you should be okay. MASSIVE curve. the two best tips are to:

1. write stuff down on the exam, even if you don't know wtf the question is even asking!!! You get points for anything and/or written conceptual answer (you will only get 0 on a question if you leave it blank).

2. GO TO DISCUSSION!!! I actually learned so much from doing the discussion worksheet even if I didn't understand anything in lecture that week, plus the people in my breakout rooms were pretty cool. IAN powell i love you <333

Finally, Regan is so funny. I actually enjoyed this class much more than I expected (finally got my first A in college physics!). the average for midterm 1 was i think 58, midterm 2 was like 65, and idk for the final but i got like 64. I still don't know wtf AC current or relativity is. You will be FINE.

Regan is...interesting. He skips the Physics 17 review that's scheduled in the beginning of 115A and focuses on special relativity: his favorite. As you make your way through 115A with Regan, you'll see that he has a problem with h_bar, energy, momentum, mass, and Griffiths. Anyway...here's a longer breakdown:

1) He assigns a lot of homework. Problem sets are mostly from the textbook (which is good), but the Regan specials are a hit or miss. His lectures are not that helpful for the HW (as he kinda just talks about what he finds interesting), but once in a while (maybe the day before the HW is due), he will say some useful stuff for the HW. He expects you to read the textbook (without telling you to read the textbook), so read and do the HW.

2) His exams are...interesting. If he gives a question similar to the textbook, be sure to get full points on that. The Regan specials are hard to do. Most of the time, I'm not sure what he's asking on his questions. If you can reach him during the exam to get clarification, please do so. HIs questions aren't necessarily impossible, but they are just worded confusingly. If exams were in-person (or synchronous), I would've asked for clarification and scored better. His curve is nice though, so that's good.

Overall, Regan is a funny guy. He's very likeable and is happy to talk to you about almost anything during office hours. He loves physics and he wants you to love physics too. But, his exams weren't that good and he thinks we can work faster than we actually can. If you have to take Regan, it's not the end of the world (as his class was kinda fun), but be prepared to do some work.
