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.

Professor Ioudina is a pretty fair professor. Her tests are on material that she thoroughly covered, she is always available during office hours, and she gives out tons of extra credit opportunities. She does have a bit of an accent, but it's not that heavy. You get used to it very fast. She usually is also willing to give a few extra points on homework and exams if you go talk to her about it. The homework she assigns is pretty tough, definitely way harder than the exam questions. Going to lecture is a must, as she does problems that you will be tested on. Don't rely on the book, it is REALLY unhelpful. I came in to Stat 100A expecting horrible things due to some previous ratings, but to my pleasant surprise, she wasn't bad at all! Stat 100A is not an easy A, but it's definitely manageable. If you've never really taken a Stats course before, (like me) you'll get a lot out of this class with this professor.

Winter 2020 - Professor Sanchez is infamous among the stats professor and I took her class knowing it was going to be a very rough experience. My expectation for her was low as yours will probably be, so surprisingly she did exceed my expectations. She is not as bad as other reviews describe as long as you follow her "rules". Some things to note: 1) She takes attendance every single class. Sometimes twice every class! Sometimes it's on a sign in sheet, sometimes she roll calls, sometimes she tells you to turn in a in class exercise, sometimes she calls on random student's name to answer a question, sometimes it's all of the above. 2) There are a lot of in class participation points throughout the quarter based on the correctness of your answer and you will most likely not be given much time for those. However she is nice enough to let you drop the lowest two. 3) She assigns official homework once every two weeks. BUT, there is often smaller, shorter take home exercises that she will assign in class(and she may or may not post on CCLE about it). So pay attention in class!! 4) There are two quizzes in addition to one midterm and one final. She takes these assessments very seriously and will write you many many many bullet points on rules to follow. FOLLOW THEM! DO NOT OPEN YOUR BACKPACK WHEN YOU ARRIVE IN THE EXAMINATION ROOM. One time she was very annoyed at a particular student who looked through his backpack inside the classroom before she handed out the assessment. She yelled at him in front of the whole class and order him to sit at the very front. 5) Homework needs to be turned in within 10 minutes of starting class or else she will begin to deduct points. Try to turn it in BEFORE CLASS BEGINS, or else your P(getting yelled at ^ humiliated) = 1. Despite my comments above, as long as you follow her rules and pay attention in class, have a decent TA, attend office hours, you will do just fine get at least a B+. She gets through a lot of material and you will feel like you've mastered a lot of material after her class. You learn a lot, more than other more "easy" stats 100a professors. And a bonus, she is quite entertaining, the way she talks, her sarcasm, and her occasional analogy of probability and life/death is quite accurate. She is very intimidating, but deep down, I believe Juana truly cares for her students. Shout out to Lenny for being an amazing TA!
