When I first enrolled in this class I was feeling almost desperate because the other 100A was already full, but it turns out that this class is really different from the bad comments from bruinwalk. Dr. Jaffe is a really cool professor who really wants to communicate with students and tries really hard to explain all concepts. He is really really approachable and would keep explaining one concept until everyone feels okay about it. He has a textbook which is really overpriced. I never read that book and relied entirely on the module and still got an A+. His tests are all really easy, especially if you have taken stats classes before or have basic understanding of hypothesis testing and probability. He allows students to have one cheat sheet and curves the scores whenever needed. Overall, I'll rate A- for this class and A+ for Dr. Jaffe.

After having heard horrible reviews about Jaffe I went into the class with low expectations. I am happy to say that I think Jaffe has made great strides towards improving his class, and I honestly disagree with a lot of the reviews I’ve read previously. I didn't go to lecture a majority of the time and I am still ending the class within the A/B range. I read horror stories about tests but was pleasantly surprised by how manageable they were, and Jaffe allowed us a cheat sheet (front and back) as well as gave us all the required formulas. The workload is manageable and the class isn’t too fast paced; modules are generally quite helpful. The one thing I will say is that it is difficult to follow the lectures if you don’t already know the information on them–if you know the information prior it is helpful so read the book and do the modules before class. Use the text and personal trainer for practice. The one thing I will say is that the TAs were absolutely horrible (I had Bufford and Kadambi) Section was rarely helpful, and furthermore they had an absolutely unapproachable air to them, thus I never sought outside help. Every review session I attended was dreadful, as it was unorganized and oftentimes the information was incorrect. There was a 50/50 shot of the BASIC CALCULATIONS being wrong. Then when students would raise their hand to point out a mistake it would create the utmost hostility.
Regardless, do not let reviews of Jaffe freak you out... He's a really cool guy and not a bad professor at all who IS taking steps to improving the class (new TAs would be great). Overall I sense great improvement.
