Summer 2019 - Wow, this guy is literally the G.O.A.T. Stats 100B is probably one of the hardest statistics courses at UCLA, but this professor made it incredibly easy to understand and definitely made the material interesting to learn with real-life examples and applications. (NOTE: This applies to his summer course. I am not sure if this will necessarily apply to his regular quarter courses). He is also super patient and helpful in office hours as well. I think this guy is underrated, especially when everyone raves about Christou. However, Almohalwas is probably one of my favorite professors so far at UCLA. The homework is incredibly INCREDIBLY helpful for the exams. MAKE SURE TO DO THEM AND UNDERSTAND HOW TO DO EACH PROBLEM because again they are VERY HELPFUL for the exams! Also, he gives out extra credit on his final and a bunch of other free points (attendance, participation, etc). Also, he is a little bit messy as the previous reviews have stated (there are files everywhere on CCLE), but he just wants to give you all of the material you will ever need to help you succeed and master the course. Honestly, the hardest part about his class is that the class is essentially straight-scaled (since everyone knows the material really well and so do really well on the exams). So, it may be hard to come back if you don't do that great on one of the exams. However, it is very doable to get an A. Literally, amazing and highly underrated in my opinion. 10/10 would recommend and would take the class again. I look forward to taking more upper-division courses with him. This guy is definitely a few standard deviations above the mean for amazing professors!

Fall 2016 - First of all, I have to admit that Christou is one of the best professors at UCLA. He is the most approachable professor I have ever seen. He usually holds approximately 20 hours of OH a week, if you have any question anytime, u can find him. His office hours help a lot and he is extremely helpful. HOWEVER, there is a big but... His lecture is usually at an extremely fast pace that if you miss one lecture, it can be really hard for you to know what he is talking about in the next lecture. He gives tons of handouts and he doesn't use textbook, but these handouts are really helpful. THE MOST HORRIBLE THING about Christou is his exam. I just finished my second Midterm and I would say it is the MOST, MOST, MOST difficult midterm I have ever seen in my LIFE. I studied really hard for the midterm but I think it would be hard for me to get a score over 30. When I got the midterm during the exam, I found I don't know how to do question 1 part a), then I moved up to part b), then i found I don't know how to do part b), then I moved to part c), and I found I don't know how to do part c), I moved to fking part d) desperately. His tests are ridiculous, those tests are useless tests that make us study really hard to get a freaking low score. And by the way, his midterm is three-hour..... a little bit shorter than a final... Honestly, you don't need to prepare for the exam because staying up late at night won't improve your score even a little. He is still one of the best professors at ucla even though he gives ridiculously hard exams. But I do not recommend to take his class if you want to get an A or if you don't want to spend hours and hours of useless time on preparing for his exams while getting a heartbreaking score.

Winter 2018 - His lectures are disorganized and it seems that he doesn't go over the examples presented in class before coming to the lecture. I hope he will prepare what examples he is going to present in his class. Compared to the couple midterms, the final was extremely hard (the average was 69 and only 2 out of 70 got higher than 90~) but he didn't curve that much. I ended up getting a B+ and people barely get an A in this class. BE AWARE that STATS 100B class itself is fairly difficult regardless of the professor who teaches. It is a theoretical basis for subsequent upper-div classes thus important to know the ideas and concepts from this class.

Spring 2017 - STATS 100B with Prof Li (Jessica) is tough, but only because the course itself is tough. Jessica teaches very well in class and always stops midway to ask if anybody has questions. She also willingly and patiently answers every question she is posed to clarify some of the things that she teaches. Her tests are deceptively easy, but actually quite challenging indeed. She doesn't have finals, she has 3 midterms instead, with the 3rd midterm having double weightage. One good thing is that she sets 1 bonus question per exam that allow you to regain some points that you might have carelessly lost otherwise, which is great! The bonus questions are challenging, but they do not cover material that she did not go through in class, so they are doable to a degree, as long as you complete the rest of the tests quickly enough. She gives 1 homework every week all of which are very manageable and she does not give homeworks during weeks when we have midterms. Also, she's very willing to help out with questions posed on CCLE or during her office hours.
