Professor Chetverikov is a straightforward lecturer. Some complain of his accent, but I had no difficulties understanding him. This course is a weeder course, and granted, a difficult one that requires time. If you spend significant time studying and practicing the problems from his lectures, notes, homework problems, and practice exams, you should not have difficulties. Having spent a couple hundred hours studying for this class (sounds excessive, i know, but necessary for me), I scored 27/30 on the midterm and 70/70 on the final. This is coming from a guy who failed Rojas' 41 class. Going into the quarter expecting the worst, it turns out that it was a blessing in disguise. The professor often goes over proofs that you will not use. Though many people complain about his proofs, it turns out that they were useful in fully encapsulating the "how" behind concepts necessary to tackle any exam question given. Lastly, exams are straightforward -- no surprises. I strongly recommend anyone willing to put in the time to take his class.

He curved down the grades and had super unclear lectures. His lecture notes were helpful, but it didn't help that we were expected to have tons of formulas memorized on the final that we had just learned.

As someone who does not have a stats background at all, I was extremely nervous coming into this class, especially given all of the bad things I had heard about it. However, I felt like Chetverikov was a super straight-forward professor and really broke things down in a clear way. Going to his office hours to ask questions about the homework or practice exams is definitely key as I felt like I would not have been able to understand some of the bigger and more complex concepts otherwise. He was extremely nice and willing to take his time to again break down the material in his office hours, so I highly recommend him as a professor. The last few lectures did feel a bit rushed, which was why I ended up looking at the last lectures maybe a week or so beforehand so I had more time to practice, which I think was the way to go when it comes to preparing for the final, especially if you don't have a strong stats background. The main complaint with the class is the grading as the final is either worth 60% or 90% of your grade and the curve is extremely competitive. I found that really understanding my mistakes from the practice midterm and finals, redoing the homework multiple times, and grinding his extra practice and lecture questions gave me a super strong foundation for his tests. If you go over basically all of the material he has given you in the quarter in the weeks leading up to the midterm and final, then the tests are extremely doable and there won't really be any surprises. It's really all about putting in the time and effort to practice a lot. The memorization can get a little intense towards the end, which is why again it's recommended to maybe look at some stuff in advance or keep your own type of personal "cheat sheet" or running list of theorems throughout the quarter. Cheat sheets are not allowed on the exams, but, given the exams are quite doable and reflect what he shows in class, I never found it to be a huge problem. Overall, I highly recommend Professor Chetverikov, especially for a weeder like Econ 41.

Content wise, this class wasn't too difficult and the professor does a good job teaching. The issue with this class is really more of an issue with the econ department, as the professor does follow the department curve (25% A, 35% B, 25% C), and by making the tests very easy, it leads to a downcurve. For context, I had barely gotten an A- in raw score, and it got downcurved to a B. For people that are good test takers, I would recommend this class. For people like me that make a lot of careless mistakes during tests, maybe not. Once again, the class itself is very straightforward, at least with this professor, but the downcurve does make it pretty hard.

While I didn't do great in this class grade-wise, I would 100% recommend! Truthfully, I feel like Chetverikov is the best lecturer and most personable professor I have had in the econ department. Unlike some other econ professors, he does not hastily rush through theorems and examples and is willing to go as slowly as needed for students to understand and ask questions. Some students may find his lecturing style sluggish and repetitive, but this type of teaching was perfect for me as someone who isn't very quantitatively-minded. Yes, he has an accent, but I don't feel like it interferes with his clarity, and he writes down everything important for the HW/exams on the whiteboard anyway. However, I will say that he was much stronger at teaching the probability portion of the class compared to the statistics portion (lots of people were confused over normal distributions and confidence intervals).

Difficulty-wise, this course's content is probably the easiest out of the econ weeder trifecta (11, this class, & 101). While some topics may take a while to grasp (like enumeration), the problems you encounter overall are a lot more mechanical/less ambiguous than the ones in most other econ classes. For a mathematically-oriented person, I can see this class being relatively easy. The course is very content heavy and requires extensive memorization (exams are closed notes and time-pressured), but I feel like if you take the time to study and grind out practice problems you should be able to get to the point where you sufficiently understand all the topics. I don't know if it was intentional, but exam averages were shockingly high (median of 93% for the midterm and 86% for the final). Practice exams are relatively good (yet not perfect) indicators of actual exam difficulty.

Here's my only gripe with this class: the grading system is unfair. HW was 10%, and all of them except the last were graded very strictly on accuracy. Here's what I mean by very strictly--if you got part A of a problem wrong with parts A, B, and C, you would not get credit for the entire problem. Exams were weighted so that the final was at least 60% of your grade, which put a lot of pressure on students during finals week. Because exam averages were high and Chetverikov strictly abides by the econ departmental curve (only about 20% of students can get solid As), we faced a downcurve. To put this into perspective, my B+ raw score became a B. So ultimately, while the content of this course is very manageable, it is still a weeder course and is still insanely competitive. I've received an A+ in a previous introductory stats course and consistently studied throughout the quarter yet received a mediocre grade. In terms of how hard it is to get a good grade, I'd probably compare it to Surro's 11 class, which had much lower exam averages but basically the same final grade distribution.

In the end though, if you really want to learn and are willing to put in a decent amount of effort, I would definitely take Chetverikov's class. He is a tough professor, but he's also extremely knowledgeable, engaging, kind, and even funny at times. Despite the class' unfair grading system, I'd still say Chetverikov has been my favorite econ professor!

Honestly this class is easy if you put in a normal amount of effort. The first half of the class (up until the midterm) it pretty basic statistics. I recommend you really try to do well on that because the final will be harder. The professor starts every topic with an example that is EXACTLY like whatever is on the homework or midterm. If you do the lecture examples with him and just take good notes, there is nothing you won't be able to figure out because he never tricks you. Everything is pretty straightforward, and I'd say the only real challenge is memorizing the equations (because you don't get a cheat sheet). Don't let that worry you though, because if you did have a cheat sheet this class would prob be a joke. So just study those equations and you're fine. I haven't taken the final yet, but he gives practice exams that (at least for the midterm) that are almost exactly the same as the test. He also responds to emails super quickly if you have any questions, and cracks lil jokes during lecture. He has a bit of an accent, but nothing that makes if hard to understand. You can tell he really cares, and he explains everything in a way that makes it seem easy. Slay Denis!!

Chetverikov is awesome. Very clear in his lectures and goes over many examples. Tests are fairly easy (multiple choice) and all the content is completely covered in class. Problem set once a week, sometimes time consuming, always helpful and good review. Definitely recommend this class!

This class was WAY more fun than any of the other required econ classes for the major. As much as I enjoyed this class, I would say Denis was a meh professor. His accent at times would drive me insane because I could not understand what he was saying. He was also really strict on the econ departmental curve. Wish he took it a little bit easier on the curve. Nevertheless, the professor's exams were so doable as long as you studied his materials. One thing I truly admired from Denis was that he kept it real, everything he showed in lectures or on his lecture notes was on the exam and just as similar. As long as you do the practice exams and ask questions about the topics that you do not understand, this class will be fun(although it was still stressful haha).

Best of luck!! :)

class is pretty calm. gives practice tests before both midterm and final, the actual test is extremely similar, i thought they were easier ngl.
Lecture attendance is not required, he posts notes after, and if you can understand them, you're fine. textbook not needed.
10% hw, these are guaranteed 100%s basically, and you can either have 30% midterm + 60% final, or 90% final.

would take this guy, his class is pretty chill.

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.
