His lectures are very well organized and enjoyable. He explains difficult concepts well, and if you regularly attend lectures and pay attention, you should do fine on the exams. The tests, however, are quite difficult, and you will have to know your stuff well in order to get a good grade on them.

The course reader covers almost everything you need to know for this course, and he goes through it page-by-page during his lectures. The textbook is useless except for the homework assignments. You could probably just borrow a copy from the Powell Library and save yourself some money.

Prof. Scerri is by far one of my favorite professors at UCLA. He grading is fair and his lectures are understandable. He utilizes simplistic concepts so the students will fully understand the basic concepts. He is a great prof. to take for any first year.

Scerri is an excellent teacher. He really knows his stuff and can teach it so most people understand. His test weren't hard at all, although some of the graders must have been out for revenge or something. His tests were alrigth because all that you had to study were the notes in his course reader - a must buy item. It gives you everything he will show in class so you can pay attention to what he's saying instead of scrambling to write things down. He has really fun demos too.
The only bad things would be be his tendancy to make people feel small when you talk to him (although he loves to talk about theoretical chemisty, which is really interesting). Also, there were annoying online quizes which had almost nothing to do with lecture. Good thing about them is that you can take them as many times as you want and save the highest grade.

Scerri is a good teacher, and he is brilliant, however he knows it and so he's very arrogant. 20A is a very possible A if you learn the material, but you better know it thoroughly cuz Scerri will definitely test your knowledge, especially on the final.

not an easy professor. I had trouble keeping myself awake during his lectures. If you have Nicole O' Bryan as your TA, go to her discussion. I failed my first midterm, then I started going to her discussion and got a B on my 2nd one.

Make sure you read the course reader and do your hw

Personally, I think he is arrogant as a person, but that does not detract from his teaching. He makes the material very available with lecture notes and VOH & regular office hours. Tests are quite difficult.

Prof. Scerri is not the best professor I've ever had but I learned a lot from him. As others have said, he's very organized with his notes and lectures fairly well. I just found his class challenging. It seemed there was just too much information to cover in not enough time. I also thought the tests were harder than they should have been and there seems to be little to no curve in that class. Overall Prof Scerri is enjoyable though and I especially liked his demos he did in most lectures.

Dr. Scerri is good. His lectures are well organized and clearly presented. The demos and other entertaining aspects of the class, such as his humor, makes the class really fun to go to. His exams are fair, and they are not that hard as some people say. Those who do really really bad on the exams are most likely the ones who did not put very much effort into the class and who don't know what they're doing in college. I realize it is hard for someone not so into science to do well on the conceptual questions on his exams, because again they do require understanding, and that don't come easily when its the first time u see something as bizzare as quantum mechanics and say "what the hell i'm i looking at?". however there are plenty of calculation, "plug in" questions that as long as you put some effort in, u shouldn't get lower than a C.

Good stuff. The more recent reviews below are pretty accurate.
Look forward to the guitar performance.

I'm not crazy about chemistry, but I always enjoyed going to Dr. Scerri's lectures. He has all the notes on the overhead and in an organized fashion. He also posts his notes on the web. I think he's made me laugh at every lecture, so, even if the material is easy to you, you should still attend for the comedy. I never got a book for his class, and didn't have too much trouble. The only bad part was that his midterms were a little long, mainly the second one. Don't let this scare you, he is still much better than the other professors.
