STAY AWAY from Christou. His exams are psychological experiments, and do not measure what you know. The midterms are not inherently difficult, but there is not nearly enough time to complete them.

His final exam? A total joke. It doesn't matter how much you study you will not do well. And he tells us this! "The test will be hard and long." I don't need to hear that when I have three other finals to worry about. I ended up with a grade that I did not deserve even after all of my hard work.

Then he tells us "grades will be submitted on Tuesday" and they don't appear until a week later.

I am NOT taking Christou for 100B solely because of his ridiculous final exam.

Even though Christou is very generous for giving As and Bs, he is a shitty lecturer. I am not saying that he can't teach, but it is just like he went over everything so quickly and he did a lot of proofs which have nothing to do with the HW and exams(Most of the time). I mean this is a theoretical class like Math 115A, i don't think it is necessary to show us the proof. One last thing, there are 3 exams, and some exams are directly from his lecture notes but not on the hand out. So you better drag your ass to class everyday. Good thing about this class/him is that he gave out shit of As and Bs and we don't need to buy books.

The person who left the review before this is either not cut out to be in this type of class or didn't attend because Christou is easily the single nicest and best math teacher I've had out of 8 at ucla. He is very straight-forwards, very friendly, and very easy. If you go to class and study what he gives you, there is no reason you shouldn't ace his open-note tests. Definitely take this class over any other Stat 100A or Math 170A or B teachers.
