I put political science 191E with him but I took political science 119, 169, and 191D with him.

Dr. Perez is one of a kind and the best professor I've had at UCLA. Yes, he might not supply you with printed notes (an outline would be nice though) but he is by far the clearest professor I've had in my UCLA career. Especially when speaking about political theory where things can get a bit confusing, he gives you a theory and lists (he says 1, 2, 3 etc) at each of the explanations and ALWAYS asks the class if they understand and if he can move on. In terms of clarity, you will never have a problem with him.

Office hours- he has office hours and he communicates via email very fast (less than 24 hours and in depth). Unlike other professors I had that never responded to my emails, he will respond to each email you send.

Many people assume that since he is Israeli he is going to be anti-Palestinian and radical- and I am glad that he is a true representative of the majority of Israeli, liberal and on the left. He does not mention any bias in his courses and always states facts and lets the students make their own opinion (although most of the time, except of the seminar, isn't really about making opinions). He criticizes Israel where he feels like it is appropriate and tries to answer hostile questions from anti-Israeli students with straight facts and nothing else. As a matter a fact, some students (Israeli and/or orthodox) actually dislike him for his very left ideology. Therefore, don't come into the class thinking you'll get a bias opinion.

Grading- Perez is very fair. For 119 and 169 you have a midterm and a paper from weeks 5 to 7. You get the midterm first with about 5 articles that are not in the syllabus for the final (will not be included in the final exam). You read them, summarize them in like 4 pages or so, and write a 3-4 page essay (something of that sort). The same thing is with the paper, only it is a a page or two longer. In the end of the quarter you get a study guide for the final that you should cover WELL. I would recommend basing most of your information on the notes since Perez also talks about the specific readings in the notes.
For 191D, you write a 20-25 page research paper on your topic (along with his counseling).

Summary- great professor- TAKE HIM!
