If you don't like his style you won't enjoy the class, and I totally understand the people who don't like him. If you like to be pushed to work like your life depends on it, this is your guy. He makes you learn so much but you feel good if you go to office hours and talk to him. Definitely would take him again.

This is a hard class.

Taking 130A with Pettus will definitely prepare you for the rest of organic chemistry because of the rigor and depth of the homework assignments. The exams are challenging on time and the lectures are fast-paced so notes are hard to make but getting a satisfactory grade is possible if you attend the lectures and put effort outside the class.

I think Professor Pettus has some prejudices against Chinese American students. Honestly speaking, I don't feel right in his class.

His lectures are ridiculously fast and impossible to take notes because he scrolls through prewritten notes. However, homework is extremely effective at helping you learn the content well, if you take the time to do it properly. He is very direct and no-nonsense which I appreciate, however it may come off harshly and crude to some. Disorganized af.

I don't know why his rates are so low. As long as you watch all the lecture video, you should be ok. He doesn't really use textbook.
