Comment:
Prof. Klein teaches organic chemistry in a way that is tailored to help students learn by recognizing patterns rather than by rote memorization, and I have yet to have another professor who is as effective as he was. The assigned textbook turned out to be one that he wrote himself and is as entertaining and informative as his lectures.

Best chemistry professor I've ever had. Lectures are crystal clear, he's always available, and prepares you well for exams as well as orgo 2. We use his textbook, which is amazing in itself. Lots of homework and practice required to do well, but he makes it extremely fun and made me super enthusiastic about organic chemistry. Would take again!!

Klein was hands down the best teacher i have ever had. His tests were hard but it wasn't anything he didn't teach. He made me want to go to class and as a result I love organic chemistry!

Professor Klein was hands-down the best teacher I have EVER had. I had heard of this website before, but never been on it. After taking Organic Chemistry 1 and 2 with Klein, I went onto this site to tell everyone how awesome he is. He has a knack for explaining very difficult concepts. I wish I could take his class again. Literally.

Fair tests and clear lectures. About a half the class ends up with an A or B. A is the most common grade given out.

Comment:
Klein is a great professor, he's very fair and actually wants his students to succeed. Absolutely take Orgo over the summer with him. He shows you how to approach Orgo problems, which is the most difficult and most important aspect of the subject. You'll have to work hard for an A, but it's Orgo. It's just the nature of the subject.

Comment:
Klein is a great lecturer but summer orgo is not worth it. Cramming that much material into 6 weeks is ridiculously hard. Most of the A's in this class go to the people that are retaking orgo. There is no curve in the class but he does final redemption. while this may seem ok, his finals always end up screwing people over. take orgo during the year

Comment:
If you want A, this class is quite challenging because there is hardly any curve. Klein is very nice and explains the materials very well. However, he does not go over difficult materials thoroughly, and thus it is quite common for students to panic during the exam.

Comment:
While Professor Klein is a very good teacher, he sometimes fails to go over very important points that are usually slightly more difficult to explain. This makes it easier for him to explain everything so easily in class. What's bad about this is that usually everyone panics the day before the exam, cause we all realize that he never explained some

An excellent lecturer. It really sucked when another prof. filled in 4 him 4 the jewish holidays. Not so great 1 on 1. He writes his own book 4 the class worth buying.

Comment:
He made this class very easy. If you study, you will get an A. It doesn't boil down to "getting orgo" or "not getting orgo"- it's most definitely knowing what he tells you you have to know. That's it. Only problem is, don't think his class is good preparation for MCATs. Still, easy A.

Prof. Klein is simply the best orgo prof. this university has. It's such a pity he's not teaching 2nd semester, for Townsend and Leckta just can't compare to this guy. He makes his lectures straightforward and his tests simple - if you study. If you failed his class, then there's something wrong...

He is very enthuastic about the subject and keeps lecture from being boring. He teaches at a very low level but his tests are very difficult. Do practice problems from the book!!!

His easy-to-follow lectures trick you into expecting tests on a similar level. He teaches on a low level, but tests on a high one. The absolute grading scale only accentuates the importance of this gap.

Klein - one of a kind. His lectures are very easy to follow, and everything is taught from a book he wrote - also very helpful. He does teach at a lower level and his tests are "racemic" mixtures of multiple choice and short answer questions.

This guy is pretty weird...he is very clear but teaches at such a low level it is almost condescending. He's also not a very nice person when you have questions...His tests are fine but, wow, he is so unforgiving.
