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.
What everyone has said here about her being the worst professor ever is not only true... it might be the most true thing ever said. Her lectures are the best cure for insomnia I've found yet, the material is interesting enough but when delivered in her monotonous drone, it sounds like Charlie Brown's teacher. The papers were graded much too harshly and did not encourage original thought. Hope and pray you have a decent TA because it's your only hope. I read all the reviews of her before taking this class but I said to myself "It can't be THAT bad!" and took it anyway. I wish now I had listened to the reviews and stayed away. I don't care if this is the only class you can get into or the only class you need to graduate or the only class that fits into your schedule... FIND AN ALTERNATIVE. Beg, borrow or steal, sleep with the dean... ANYTHING! If you don't heed the warnings, and still take a class with Prof. Hieronymi I sincerely hope you have a guardian angel and a really large supply of Red Bulls to stay awake.
