Just got out from 100B. TBH, he exam is actually very very very hard. The average score is around 18. However, he curve a lot. You not going to learn anything from his lecture, so be ready to go to OH and ask for help. Good thing he got 6 OHs a week. Overall, Prof. Christou is very helpful and generous on grades.

Professor Christou is by far the most interesting professor I have ever had. After about the first 2 weeks I realized I was going to have to make a choice with this class: either treat it like any other class, attend, go to discussion, study starting 2 - 3 days before the exam or make the class my entire life. I decided to do the former and I suggest everybody taking it does the same. The truth is unless you're going into research, none of this matters. Do enough to soak in the main concepts, but not too much to where you stress and question your intelligence. As for the exams, find the 3 - 4 questions that are extremely similar to homework problems or past exams and answer those, then focus on the rest. No matter how poorly you may think you are doing the curve will always catch you. I got a B+ and I'm sure if I dedicated my life to this class I could've gotten an A- or possibly A. I instead chose to focus my time on grasping the applicable and honestly more interesting topics that 101A and 102A had to offer which is a tradeoff I would take every time. Overall, I suggest you take this course IF you have the right mindset AND you are willing to possibly get a B+ or B.

Professor Christou is an extremely caring faculty member that values how much students actually learn. He is very helpful in OH, and is always happy to elaborate on axioms and corollary derivations in class. The class is very tough, with exams having an average score of ~35-37%. Don't worry, he curves the class and is very generous with your answers on exams. The homework is relatively long, but it's really helpful to go to OH and section for them. It's also great practice for exams.

Overall, love Professor Christou, and I can't wait to take 100C with him.

I have no idea why people keep saying he's one of the best and most caring professors. His lectures were all over the place, his handwriting was absolutely terrible, and his exam average was around 37, which included the free points he gave because he messed up the very first question on the exam. Despite the fact that he had a whole bunch of office hours, I don't see how one can use "caring" to describe him. He is not caring if he gave out quizzes and exams that contained materials he covered the same day, nor is he caring if he planned on going over new materials and assigned a new homework assignment that's due on the day of the final. This class with him consumed almost all my time, and I've never been so overwhelmed, even when I was taking 21 units in one of my previous quarters. People who left positive reviews should really think about if he's truly that nice or they were just suffering Stockholm syndrome and attempting to develop an unrealistic image to justify their suffering.

Christou loves this subject and his students and invests a ridiculous amount of time into office hours. His exams are crazy hard. Expect to get like 40% on them. The class is obviously curved a lot to make up for that. If you do the work and try to understand stuff you will probably at least get a B+. If there are other professors available who seem easier, probably take them if you don't care about really learning statistical theory much.

The only pro about professor Christou is how helpful he is and how much office hours he holds. Believe he held one almost every day. However, this class is super hard. You can tell he loves this subject but when he lectures he is kind of all over the place. It is rare when he would introduce a topic and you could actually understand it in class.

He does not have a textbook but instead posts handouts which are also quite difficult to understand. Most of the time I felt it was more an introduction of an idea and then a deep dive into it without really explaining it. Even something that was seemingly simple was incredibly hard.

The tests in this class were god awful, averages usually being in the 30s or 40s. The only plus is that he curves the grade for all exams. The exams are overwhelming because it is so many problems for such a short amount of time but it isn't expected for you to finish hence the low averages.

I wouldn't recommend taking this class but I also don't know how the other professors are in comparison. Christou isn't too bad, I mean I got an A- somehow and that says a lot, trust me. It was also open notes and during the Zoom stuff so meh. I highly recommend getting a good grip on all the distributions and how they connect, knowing the 100A stuff will help lots as well especially later. Good luck

Note: This review is for Winter 2021, a quarter conducted remotely for this class.

Professor Christou's class is one of the most well-known classes in the UCLA Statistics major. Initially, I was not going to enroll in Professor Christou's class, but a close friend convinced me to take it with her. The class was difficult, yes, but I found it to be worth it.

STATS 100B is a difficult class regardless of whichever professor you choose. Professor Christou was extremely helpful, providing office hours for two hours on each day for every day of the week. In lectures, he would often begin lectures by asking if we had any questions before proceeding with the material. We did not get to ANOVA, so rather than rushing he chose to omit it from the final.

In terms of assignments, it was mostly manageable, but sometimes there was not a lot of time to complete them. There were 10 total assignments, and the TA (Stephen) went over most (if not all) in discussion sections. For the assessments, they are some of the most difficult tests I have taken in my time at UCLA. The time limit is tough, but studying the material and doing the homework before the TA (to get genuine practice rather than simply copying) does help prepare you for the exams, as they are formulated in a similar manner. My one suggestion to those who take this class in the future would be to try to answer every question (and not get too involved with a single question).

If you are concerned with grading, Professor Christou demonstrated the cutoffs for A, B, C grades after the midterm exams. This helps give you an estimate of where you stand (the average is B/B+).

TL;DR: You learn the theory behind the application in the 101 and 102 series. Exams are difficult, but the curve is rather generous at the end of the quarter.

Professor Christou puts his students before anything else. He will go so out of his way to be as helpful as possible for the students, and he truly cares about our success. Yes, you've read the reviews. This class is HARD. The workload is very high and the tests are super challenging. BUT if you go to office hours and form a relationship with Professor Christou, you will find that he is very easy to talk to and he genuinely cares about getting to know his students on a personal level. He'll ask you about your life and talk about things other than stats because that's just the kind of professor he is. He really is an amazing person and this class is WORTH IT. You will be challenged, but you will end up learning a lot, and honestly, you will feel a lot more confident in your abilities as a student after taking this class. You will never feel Imposter Syndrome again haha!! Trust the curve. He curves very generously at the end. The GroupMe in this class is also group therapy so just know that you're not struggling alone. Professor Christou is truly a one of a kind professor and he has most definitely left an impact on my UCLA experience.

This class is good but you need to settle into it. If you really understand the homework questions and quiz questions, you will probably get an exam score that rounds to an A or a B (raw scores will be very bad) . Be okay not answering all the test questions -- just try them all and optimize for the ones you know and you will be fine. There is a lot of work but it wasnt nearly as bad as some of these other reviews make it out to be. Professor Christou cares about his students .

Professor Christou is legendary. He is the professor who truly cares about students' mental health. He holds almost every day for his office hour (even on weekends). Yes, his exams are goddam hard, but his curve is really generous, which means almost everyone fails. I have not seen any student who received below a B-. 100% recommend taking the course with him. He knows his stuff, and you can learn a lot if you try.
