I really do not want to sound mean, but this professor is by far one of the worst at UCLA. She stumbles over ideas, confusing the students. She asks the class: "Is that clear?" and she expects someone to raise their hand and say what? "Uh, I have no idea what you've been talking about for the past 30 minutes." She is so unclear and extremely difficult to understand and follow during her lectures. Her teaching style needs a serious overhall.
I just finished taking Philosophy 22W with Hieronymi, and I must say that I was pleasantly surprised. After reading the reviews I expected to be committing GPA suicide, but I ended up getting an A in the class. Look, the class was hard, but if you studied, went to lectures, and office hours to talk to your TA before turning in papers, it was quite reasonable. Although I ended up with an A, there were only three people in the class, other than myself, who did so, and there were 80 people in the class. If you are interested in the subject, then by all means take the class, you will get alot out of it. She does a good job of preparing you for her tests, some of the questions were almost word for word from lectures. I would recommend her, but only if you are ready to work for an A, and are not expecting one to be given to you.
