Honestly, Christou is the best professor I've ever had at UCLA.
You can really learn a lot from this class if you put your effort into it. He really cares about his students and hopes them to be successful. He gives about 12 hours of OH every week, and he is always there ready to help you. He knows his stuff and what he expects us to learn in class.
As all of you already know that this course is extremely hard, the average of the midterms is just a little bit over 20, and it's becoming lower and lower every year. There are in total 16 homework assignments this quarter. You need to be prepared for all of these before you take this class.
In the exam, you need to clear your mind to do it. Sometimes you will find yourself cannot solve any of the questions on the exam, but just write down what you know about related to the questions, then you will receive partial credits where most of your points come from.
During the quarter, you need to be optimistic about your grades and assignments. Professor Christou is not meant to make difficulties for all of us, but he wants us to learn something beyond the scope in the exams. He told us that "grades are just numbers, what matters is understanding the material". Try your best to learn, not just to try to get an A. You may feel bad about it at first, DON'T DROP THE CLASS simply because you thought you did not do well in the exams. At the end of this class, I believe you will find Christou a very good person.
Enjoy it.

Professor Christou might be the only stats prof here who actually cares about you. Yes his tests are brutal, his homework makes you want to cry in the middle of the night, and sometimes his material is so challenging it makes you question your future academic path. But at the same time, he is the kind of professor who will push you to be a better, more prepared student.

some logistic:
15% homework (there's like 15 homework)
20% midterm 1
25% midterm 2
40% final

Homework is graded on accuracy, but with the TA and some smart kids in your class, you should be able to get 100%. Both midterms are hard, buttttttttt the curve works in your favor. For my class the average for the first midterm was around 22, and if you score above high 20s you are in the A range. For the second midterm the average was around 20 as well, and if you score above 25 you're in the A range. Coronavirus happened so Christou made the final optional, which just shows you how much he actually cares about his students.

This quarter is rough, but I am happy that I took 100B with Christou even though people keep saying it would be suicide. He actually cares about his student learning and have 20 hr of office hours per week. He even remembers my name ??? (Im an internatonal student so my legal name is very hard to pronounce for him but he still tries to do it????????)

If you like challenging yourself, please take 100B with him. He is such a great professor and you will end up loving him.

I love Prof. Christou as a person but not as a test maker. I had to study my ass off, sacrifice my happiness/health/social life throughout the qrt to get As on both midterms. (Though I failed the final and ended up with an A-, which sucks.) Some naturally talented people grasp the material faster, and the professor does not understand his exams are just not possible even to some most hardworking students, because of the presence of those talented students in his class (those people who would get 60-almost 90 regardless when the averages were around 35-40)..

If you have a good mathmetical background and wanna get the most out of this course, go for it.

If you want an A, but don't have a good mathematical background, and want to keep your health/integrity/social life/happiness, take this class with a different professor.

But I have to comment on how great this Professor is. I'm a senior, but I haven't seen any other professor who is as kind, caring, and friendly as he is. He is genuinly interested in his students and wants to get to know them more. Although I hate his exams, he is too great a professor I would still prefer his course to some other professor's.

For Stats 100B the midterms were cake, but the final exam was nothing like the midterms. It was not even like the practice problems he gave out in class. The result? A grade that does not equate to anything. The final exam does not measure how much the student knows. Also, he tries too hard to comfort the student. He will say that he will reward students for hard work and attendance in the end. He doesn't. So just remember that your grade is based solely on how you do on the midterms, HW and final (as with most classes).

I must say that I learned hardly anything over what I learned in AP stats in 11th grade! The stats 100 series coupled with Christou's slow teaching style is an insult to the statistics profession. Great...I know how to show that z^2 is a chi-square variable...useless...

I can hardly wait to see how little I will learn in "100C: regression analysis."

I must mention the one time Christou threw a temper tantrum in front of several of his students during his OH two days before the final. He slammed things onto his desk, gave rude responses to students asking questions, and when I asked him a question, he responded, "not today." Then what the heck is the point of office hours?

I don't know what to say. I have a very mixed review of Christou. He is very giving with regards to his office hours and handouts so I recommend him for that, but I do NOT recommend him when I consider the invalidity of the final exam, as well as his "moodiness" and lack of application.

Are Christou's exams the hardest exams I ever took? Yes (~20-30% midterms and final averages for the class). Did I understand everything that was taught in class? Fuck no. Do I recommend you take this class? Definitely yes.

People on this page keep complaining about how hard and stressful his class is, but honestly, it was one of, if not the best, classes I ever took. First of all, you're basically guaranteed a B no matter how poorly you do on his exams (one of my friends got single digits on all of their exams and got a B+). He just cares about whether or not you are trying to learn, and it really shows in how he structures the class. There's a fat curve, so you really don't need to be losing sleep over this class. All you have to do is try to learn.

He holds 2 hour long office hours every weekday and sometimes on Saturdays (including days of exams so you can ask last minute questions). Sure, he can come off as rude or impatient when you ask him a question, but as long as you're not asking a question about a foundational topic that was taught a month ago (which at that point is just on you), I promise that he isn't actually upset. He sounds like he is, but trust that he actually cares and is trying to help the best he can. A lot of people complain that he isn't very helpful in answering questions about the homework or practice exams, but that's mostly because he's just trying to guide you to solve the problem rather than just giving you the answer. If you want answers, go to ChatGPT or Gemini, you'll get better results there. If you like the idea of developing problem solving skills with the help of some guidance from Christou, go to his office hours (really recommend). I promise you, this is the best class in terms of challenging yourself and becoming smarter. Remember, you're guaranteed a decent grade, so this is a great opportunity to learn how to study/think without worrying about failing. If you're thinking about grad school, this will be the most helpful class for you.

Shoutout to the dumbasses who are ENTIRELY reliant on ChatGPT, Gemini, or any other LLM to get through uni. As long as you can think for yourself, this is a great class for you (and also guaranteed an A- at least probably).

Professor Christou is one of the best teachers in the stat s department. If you put the effort into this class, it will have a transformational impact on your understanding of mathematical statistics – this class almost feels equivalent to doing a year's worth of stats classes. With that said, there's a price. This class was more work than my other classes put together – I'd frequently spend more than 8 hours on the weekly homework (and yes, he even sets homework in midterm and finals weeks). You also cannot afford to drift off for even a second in his lecture otherwise you're in big trouble. His tests seem impossible while you're taking them (think single digit percentage averages) but he curves the class generously so your final grade won't be too far impacted. In short, this class is like medicine: if you take it, you'll do well – but you won't enjoy the process.

so obviously taking this class was immense suffering, but having gone through it i do see the point in the exams being so difficult. This class made me remember material from past classes, think harder, and problem solve faster than any other undergrad course so far. I learned 100a content (permanently) from this class, not 100a. I will never freaking forget anything related to gamma now!!!! anyways to study, 1. rewrite all the notes, proofs included 2. redo all the homeworks with relevant content 3. spam practice exams. it is actually not that hard to get an A because if you study least that much, many people will do much worse than you!!! AI is also making your classmates worse so if you actually learn you will be reasonably ahead of the curve :) the final was the worst exam i have taken in my life. for the last hour I did not write anything down, I could only look at the problems and laugh. But still the other 100b profs will actually give Cs so I recommend you take it with Christou :)

Good dude but horrible exams and tough hw.

A difficult but very rewarding class! I feel that I'm really learning something.
