Chetverikov was very clear in his expectations and was always willing to help after class. Wookun Kim and Changsu Ko were very capable TAs.

The lectures and homework assignments were extremely useful. Professor Chetverikov was very helpful and patient with answering students' questions, even right after the lectures. While most professors are unwilling to stay after class to talk to students, he makes sure that everyone who has questions gets a chance to ask him directly. The weekly homework is relatively short and very doable, not to mention, great review for the midterm and final. The midterm was extremely easy, as long as you pay attention in lecture and understand all the homework problems (including non graded ones). The final was slightly more difficult, mostly because its 70 questions. He posted 2 practice finals, but I only did one and reviewed all the homework, which was enough to do very well on the final. Overall, one of the most interesting classes I've taken at UCLA, even though some topics weren't that engaging.

The weekly homework is relatively short and very doable, not to mention, great review for the midterm and final. The midterm was easy (I got 100%), as long as you mildly pay attention in lecture and make sure to understand all the homework problems, including non graded ones. The final was slightly more difficult, mostly because its so damn long. He posted 2 practice finals, but I only did one and reviewed all the homework, which was enough to get 67/70 (I also guessed on the last 3 cause they were kinda hard and I just wanted to leave lol). Overall, one of the better classes I've taken at UCLA, even though some topics weren't that engaging.

Denis was a great professor, though I didn't spend much time in class because I had another class at the same time. He's very friendly and always willing to answer questions. He assigns grades based off of rank within the class, so make sure you step up when it comes to exams. Scoring above the curve is a good way to get an A. He makes the exams pretty easy, especially in comparison to the reviews from previous quarters. The downside to this is that you definitely need to get an A (or something close to that) on exams in order to get an A in the class. Averaging a C on exams however, is probably enough to get a low B or high C.
My advice is to pay close attention to the homework and do all of the practice problems he gives you. Doing all of those are probably enough to get an A in the class.

Disclaimer- This was the first online quarter
Let me start off by saying I didn't like the class. This class was the hardest econ class ive taken ( and ive taken 1,2 and 11) The professors lectures were a drag to listen to and most of the time went like 10-15 mins over the designated lecture time. The lectures were recorded but they were boring to listen to, I almost never did them in one sitting. As for the syllabus, he provided 4 different grading scheme due to the different situations going on. HW was always 10%, Midterm was either 0/45/30/60% with the Final being 90/45/60/30% respectively. As for the actual content of the class, the professor's lectures weren't very clear. He stated more theorems, definitions and proofs than showed how to use them in an actual example which is in my eyes the most important part because he didn't ask any theorem/definition/proof questions on the exams. The midterm was pretty straight forward, the average was like 90-92% depending on what time you took it (he provided 8am and 8pm exams to accommodate time differences). The high average was undoubtably due to people collaborating, bc the professor did not write an easy midterm. The final averages were 85-89% (bc he again provided 2 different times for the exam). The final was 70 questions and was not easy at all. The way he calculated grades was also quite unusual because he calculated your grade compared to the people who took the midterm/final at the same time as you and not compared to the whole class. I didn't do well on the exams but still managed to get a C in the class. But it was definitely a difficult class.

He follows the department curve strictly:
25% A
35% B
25% C

You cannot use a graphing calculator on exams to compute calculations. Only a 'simple calculator' is allowed. It is slightly unfair as other ECON 41 Professors allow students to use one.

Homework questions are graded for accuracy, and are due weekly. All work must be shown.

It was bright and sunny on the first day of lecture. I strode confidently into class with my head held high. Students were chattering in the lecture hall as Dr. Chetverikov summarized the syllabus. I was paying attention somewhat half-heartedly: I’d gotten a 5 on AP Stats; what could possibly go wrong?
My curse was answered when the professor began discussing his grading policy:
“Homework is worth 10 percent of your grade. There are two grading schemes, and if you do worse on the midterm than the final, the final exam will be worth 90% of your final grade.”
I was shook. But it got worse.
“Twenty-five percent of you will get As, thirty-five percent get Bs, twenty-five percent get Cs.”
A student raised his hand: “Professor, you account for the remaining 15 percent?”
Dr. Chetverikov grinned, casting a softly menacing gaze across Broad 2160E, and the whole class fell silent, because they all knew the terrible truth.
“I’m not afraid to down-curve a little if needed.”
I knew then and there I would have to frantically claw my way above 75% of the class in order to avoid a scolding from my mommy.
When our midterm results came in, I gasped in horror: the upper quartile was a perfect score. I was thankfully within the bracket. But the final distribution would be entirely determined by homework scores and the final exam. And my homework scores sure hadn’t been stellar.
I decided I had to win this battle at any cost. So…I made a point to be as annoying as possible during lecture. I would munch potato chips, knock over my water bottle, ask extremely stupid questions in the middle of class. Anything to stall the class or distract my rivals.
The strategy paid off in the end…
…or maybe it’s just because 2/3 of the class just stopped attending lectures after the midterm and my work was cut out for me anyways…
…but I’d prefer to think the former.
If you are considering taking Econ 41 with Professor Chetverikov, I wish you luck on your journey. You have my sword.

Out of all of the pre-requisites for the Economics major, this is definitely the hardest class. If you do not have a strong background in Statistics and are not prepared, the later content in the class will be difficult to process quickly and stack up against you. While I did struggle in this class, I do not fault the professor as I feel like he conveyed the content well enough. Chetverikov has very engaging lectures despite the tough content. A lot lays on final, so prepare accordingly and do not blow it off for the last couple weeks. Hard class, great professor.

I highly recommend this class. If you watch all the lectures, you’ll perform well on the exams. The midterm was incredibly straightforward, with an average of 29/30, and the final, while slightly more challenging, was still completely fair. The professor is absolutely fantastic—one of the clearest and most organized lecturers in the Econ department.

Quick background, I had no stats knowledge coming into this class; however, I did extremely well in econ 11 and 101 so I thought this class would be easy. I ended up with a 29/30 on the midterm (after thinking I had failed) and a 40/50 on the final. I definitely could've utilized more resources (ta and prof OH), but I did put in an inordinate amount of time self-studying, especially compared to 11 and 101. Chetverikov is by no means a bad lecturer but the material is incredibly dry including the "real-world" examples. He follows the curve to a T so if you want an A you have to do better than your peers. My biggest takeaway from this class is stats isn't my strongsuit.
