If you like math or language, you will be fine. You will learn how to do all the problems by doing the homeworks, or by referencing the slides or attending office hours. (There are TONS of office hours.) There is some room for error in this class, but not a lot.
If you can do the homework, you're good.

For some people, logic comes easily to them, for others, learning these concepts is like pulling teeth. I fall more into the second category of people. With that said, I felt that the classes explained the concepts very well, and definitely helped me to learn the concepts. I took this class when classes first went online, so I actually did not go to the lectures and would just watch the videos later, and it worked out fairly well for me.

This class is by far one of my favorite classes I've taken thus far--due mostly to Professor Levy's brilliance as a lecturer. He's extremely funny and very clear with the material; I'd suggest against skipping any lectures, for that reason, as it might be difficult to catch up without his explanations. There are a few homework assignments each week through Logic2010, which is a bit of an eyesore of a program but nevertheless pretty easy to use once you get the hang of it. This class isn't like a typical philosophy class and is more along the lines of doing math, if anything, so if you're good with that type of material I strongly recommend this class (and even if you're not, it's super fun and satisfying once you get the hang of it, which should be easy enough with how passionate Levy is about the subject). There are two midterms and a final exam as well. My grade breakdown was an 89 on midterm 1, 100 on midterm 2, and 99 on the final, and so I ended up with a high A. I made some small mistakes on the first midterm, but other than that, the material was pretty easy to understand if you do all of the homework. Levy also holds gala review sessions prior to each exam which are super helpful, especially if you're struggling with certain problems. He has tutors walking around to help (and Levy is also available to help) and these sessions go for about 3 hours. These sessions on top of doing a bunch of the problems on Logic2010 will basically ensure you kill it on the actual exams, especially because Levy gives practice exam sets that are essentially the same structure as on the actual exams. Despite the class being at 8am, it was super enjoyable and it feels great to have this neat skill under my belt. I highly recommend this class :-)

I absolutely loved this course! Both Professor Levy and his TA Christian knocked it out of the park! As someone that isn't very skilled in material of this nature (as it feels very MATH ADJACENT) their engaging approach and especially merciful approach to grading rapidly made this my favorite course, for my first quarter at UCLA.

The course was graded per three exams (two midterms, final) and homework assigned throughout the course; all of which done on the Logic 2010 program (...kinda fun, when it isn't terrifying!)

The only criticism I can muster is for the tutors chosen for the class... While the vast majority of the tutors were helpful, although beleaguered by terribly confused students (myself included!) a tutor by the name of "Rocky" stood out as particularly rude and unhelpful. The specific case of this that comes to mind was in one of the gala review sessions prior to the second midterm exam, where when I struggled with a specific problem he seemed more interested in flaunting his "brilliance" on the subject matter by using evasive terminology, which Professor Levy hadn't lectured on. Worse, upon asking for more clarification he loudly called out to another student with their hand raised, to apologize for me "taking so long!"

Suffice it to say: You will want to be mindful of who you ask for help, where the lectures and FREE textbook do not allay your confusion.

In conc., Professor Levy is a fantastic lecturer and I hope to take more classes with him during my time at UCLA!

I had no idea what this class was about prior to taking it. Despite it being at 8AM and for a whole hour and a half, I enjoyed every second of it. Not only is professor Levy funny and approachable, but the content is not hard at all. If you enjoy math at all (although I would not compare this course to math as much as other will) you will enjoy this course, and if you don't, it isn't too difficult anyway. 10/10 professor and course.

He is a good teacher for an intro level class. He is funny.

Very easy As. If you are a familiar with STEM stuff then you are probably gonna get an A because his exams are pretty much like very solving math-like logic problems. As acknowledged by others, his lectures are extremely slow, and if you are good at self studying you can do most stuff by simply reading the textbook. But don't miss his lecture on invalidity because it's the hardest part overall in this course.

Funny, engaging professor who makes it abundantly clear that he's more than willing to offer help to those who come to office hours, ask questions, etc.

The 8-10am lectures were brutal, but I went to most of them. I've heard from classmates that skipping lecture and going to office hours to learn the material is way more efficient, and I'd probably agree with them because lectures stopped being helpful after the first few weeks; he does a way better job at explaining sentential logic than predicate logic.

Overall fun and easy class if you put effort into the homework.

This class was honestly a great class and you'll find yourself saying "this class is so fun", whether you like philosophy or not! I came into this class because I had to fulfill a philosophy prereq (for CogSci) that was not really philosophy based, so I took logic. It's really annoying sometimes and the homework gets tedious and long, but if you put in the work you will do well. I would definitely recommend making a friend to help eachother out with homework, because it's a lot at times. I struggled a lot at first, but noticed that prof Levy really cares about improvement, so I ended with an A-.

The breakdown is as follows:
20% HW - 100%
20% Midterm 1 - 74%
20% Midterm 2 - 89 %
40% Final - 92 %

Def recommend!

I know a lot of people who don't show up in class. Always go to the TA's office hour. They are so helpful. Professor Levy is funny and his lectures very engaging. As long as you do your homework, you'll be fine. Really regret that I missed some class. Just can't always make it at 8 am.
