For EPS SCI 9 with Professor Jewitt, I generally enjoyed the class. The lectures were engaging and interesting, with a small twist of humor that garnered a small chuckle from the class. He was thorough in explaining the topics at hand, but sometimes the topic did seem to drift from the core of the class. For example, we spent quite a large amount of time on Earth's geology (i.e. plate tectonics, atmosphere) relative to the other topics of the course. While I'm sure this is important, it threw me for a loop. Nonetheless, I still enjoyed these topics.

With regards to grading, this quarter was a particular circumstance because of the cancellation of in-person finals due to the coronavirus. So, Professor Jewitt canceled the final and accordingly scaled the midterm and labs. While it is true that the midterm would have been harder than the final (he was going to provide us with questions on the final), I cannot complain about grading because he provided up to 20% extra credit, which is extremely generous. All in all, though this class was a bit different from what I anticipated, it was still extremely interesting and low stress.

TL;DR: Professor Jewitt is a professor who is passionate about the topics which he teaches, passing this enthusiasm onto students while at the same time providing sufficient extra credit to help students focus on learning, not grades.

So I got an A+ in this class, thanks to all of the extra credit.
Even though I tried, I didn't feel like I learned a lot. The class wasn't super clear and discussion did not relate to class at all, which was frustrating, but I can't complain. The discussion quizzes were really easy and came straight from the worksheets. I found the midterm to be pretty difficult even though I studied, but the average was low so it balanced out. Dr. Jewitt was really great and cared a lot about our learning. I thought he was wonderful.
It's not a super structured class, but as long as you stay on top of discussion quizzes and the extra credit you'll be fine.
If you really care to learn about the Solar System, you'll have the opportunity to; if you don't care to learn about the Solar System, you'll find out just how interesting the subject is and it won't be too overwhelming.

My review of this class is going to be a little skewed because the final was cancelled because of coronavirus so if you are taking this after this whole thing has blown over, my experience might be a tad different. But overall, the class itself was good; he posts the slides so you don't have to technically go to lecture. But Professor Jewitt is really funny and endearing so I showed up most days, just because I felt bad missing out on lectures taught by someone so amazing in his field of work.
Midterm: The midterm was super hard. I got a 55, my first failing grade at UCLA. I studied so much, but I studied the concepts and facts, rather than obscure equations. The midterm tested for very small details and had way more math on it than expected. I got up in less than 30 minutes and just handed it in lol. The average was a D, so don't feel too bad about it. BUT, even though I failed the midterm, I still ended the class with an A. I don't even know how I did that tbh.
Extra Credit: He offers like over 20% extra credit and I am telling you right now: DO ALL OF IT. He assigns the extra credit early in the class and you may feel like your grade is alright, but do it anyways because the midterm will most likely kill that and you don't want to be scrambling to do the extra credit.
Labs: You have to go to labs for participation. Each lab is worth 6 points - 1 point for showing up and the other points are from the lab and lab quiz. You get to drop your lowest two lab grades too.
Final: He cancelled the final for us so I never took it, but from past reviews people said he gave a study guide that was basically the whole test :)
Homework: There's no homework. At least for my TA, she checked the labs for completion and then posted the answers later so you really don't have to try on them.

Professor Jewitt is a great professor- he's super nice, funny, and knowledgeable about the topic, and he makes the lecture and subject very interesting. That being said, I stopped going to lectures about halfway through the quarter (just because I was lazy and didn't want to walk to campus), and he posts the slides he uses for his lectures and they contain all the information. Grading wise, it's based on participation and quizzes given in discussions section, which are fairly easy (and your two lowest scores will be dropped) There's also a midterm that's actually pretty hard, but I managed a 26/29 on it. The final exam is worth the most, and from previous quarters it seems like he basically gave all the questions for the final beforehand, but for this quarter the final was cancelled due to the corona virus. He also offers like 20% extra credit to yoUR FINAL GRADE for doing stuff like watching movies and going to different science places around Los Angeles, so if you want an A in the class, you should be able to if you put in the effort. All in all, this a great and easy GE to take that I highly recommend

Best science Professor ever. Take this class even not require. Easy, fun, interested.

Fun class. Definitely take it. Super easy since there's a crazy amount of extra credit. You'll do poor on the midterms but there's so much extra credit that it won't matter. Jewitt is kind of a troll which makes the class funny. Maybe don't take it when you're a freshman. You'll probably be turned off by his style. But if you're a tired senior like me, then it's a really great time. It was funny time.

Overall, with it being online, I had a hard time focusing and actually going to lectures. The labs were very easy, though. It's an easy A if you put in a little bit of effort, and the extra credit he offers is VERY nice. It definitely saved my grade.

Looking past his abundant political comments/ awkward videos/ etc, this is actually a fairly okay GE. Exams are pretty much memorization off the slides, but he does ask questions to throw you off. For example, I felt as though the first and second midterms were okay, but the final was so strange with wording and so heavy on memorization that I felt like he just wanted to mess up grades. However, the extra credit will save you though, so I highly recommend doing even the most mundane extra credit assignment (like writing a 5-10 page paper for extra credit). For reference, I got a B on midterm 1 (10%), an A on midterm 2 (10%), but a C on the (45%) final (did all the labs, 35%, and did well on the quizzes) and I ended with an A thanks to the extra credit.

I feel like I really learn a lot in this class, and professor David makes the lectures funny and easy to follow. Definitely recommend this class!
