Dr. Moon is a really nice person. He cares for the students and tries to make sure students understand and learn the content. However, I won't say he is making it easier for us. Attendance is mandatory. Some parts are 10-20-minute video lectures, so you have to learn it by yourself, exams are not curved, and THE WEEKLY QUIZZES ARE HORRID

Professor moon is accessible outside of class and seems to care about his students. His class is HARD. First midterm average was below a 35%. No curve for exams either, so if you fail, you fail. Weekly quizzes are online but take hours and are very difficult. He is nice but this class is like a full time job, I don't have a life outside of it.

New professor so still learning the ropes. I think Professor Moon is very caring if you make an effort to go to his office hours because he is very helpful during that time. Only thing is he doesn't post notes, so it's hard to get that information if you aren't able to attend lecture. In general a very hard class.

Dr. Moon was a pretty good professor for CHEM105A. His lecturing is super clear and he displays all the calculations clearly. The unfortunate thing is that he only posts the blank slides so if you want to redo the question you just have to remember the answer. You do have to show up and study for quizzes. Very accessible outside class.

Dr Moon's emotions reflect the way he teaches (not showing work on a problem due to the actions of students in a previous lecture). However, his exams are hard at all and are very reflective of the amount of studying you put in. He grades fairly and even includes extra credit on the final exam. As long as you do practice problems, you'll do well.

Personally, I really enjoyed Dr. Moon's lecture style and course structure. Yes, there can be a lot of busy work outside of class (GRNs, Worksheets, HWs with lab work), BUT it really keeps you accountable/stay on track with the content and balances out your grade. I truly recommended him for CHEM 105B; he's so supportive and a great professor!

I actually like him for 322a because his teaching style is very methodical. Every week I know exactly what needs to be done. O-chem is hard no matter who you have so be ready to put in the work, especially before midterms. He does group quizzes the week before so you know how much you need to study. Content checks (unlimited attempts) help too.

His lectures are concise and helpful because he uses the same monologue for every similar problem he solves. The types of questions on exams are the same as the types he puts on the lecture slides. Yes it is a lot of work, but if you do all the practice questions and write down the types of problems he could ask, you're guaranteed above a B.

Dr. Moon is a GREAT lecturer. Honestly one of the best chem prof I know. Although there is a lot of work to turn in, that is his method of getting you to learn and understand the material well. Tests are challenging, but you will do fine if you study well. attend every lecture and you will get that A

moon is actually a really good lecturer and he explains everything well. while there is more work you need to submit i feel like overall the amount of time and effort you have to put in for moon vs the other prof is the same. it also means you get more chances to raise your grade outside of exams, which i really liked.

Dr. Moon is my favorite professor at USC. His lectures are always interesting and easy to follow. I actually learned to enjoy chemistry especially the last midterm concepts and I hate chemistry. A lot of work but it helps prepare for the exams. Study EVERYTHING. He is an amazing professor and his office hours are extremely worth going. Sweet!!

Great lectures, hard exams. I honestly SUCK at chem but I did the HW, practice, textbook problems, old exams/quizzes and went to his office hours 3 times a week and was able to get an A-. He gives lots of extra credit (20 points) + on the last HW assignment 3 points extra if u get 5/5. He drops 2 HW assignments. Hard class but doable

Dr. Moon knows the challenges ochem faces and counteracts them by providing his students with tons of support. He explains challenging concepts really simply, provides tons of practice sheets/problems, and has lots of office hours. This class is not easy, but you gotta put in effort to use the resources Dr. Moon provides. He is also funny

Very short with students. Organized, but he won't accept questions sometimes so that he can stick to the lecture schedule. Tough grading, barely any partial credit. Last two chapters had no worksheet or problem sets and were more biochem focused. Expected knowledge because it was related to his PhD.

The exams can be excessively difficult and he can be quite petty. But he explains things so well, hence the 5. Would not take again though lmfao.

Easily the best prof I've had at USC--clear and concise lecturer and intentional with everything he does, so as long as you pay attention and do the required work you'll do well. Exams are set up so you absorb the content better and there's always an abundance of resources to study from. There's also significant opportunity for extra credit.

Not the hardest class, but not the easiest. Each midterm was only 6% of your grade so it wasn't too high stakes; a lot of outside work you had to do though such as guided reading notes and weekly practice which basically made lecture mandatory . I will warn you he is a VERY, VERY creative test maker—take that how you will. Final was easy though.

Ppl who have "A" as their grades before the week of may 14th are lying. Every exam had a D average. It was to the point that he didn't do mid semester grades for us (he did it for 105b and 322a) because "I'd be giving out a lot of D's and F's". This class is ridiculously hard. Exams are really abstract. Take Kyung his averages were 100x better.

This course is a breeze if you go to lecture and do the homework. Taking high school chemistry and being decent at algebra helps. Solid amount of padding.
