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.

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.

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.

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.

so glad this class is over. denis is not a bad professor by any means but he's very strict on the econ departmental curve. more than half of the class got 97% and 100% on the midterm so he made the final HARD AS SHIT it was unlike anything i've ever seen before. everyone was at risk of getting their final grades curved down two signs but he ended up curving up and down some grades to adjust the distribution and i was on the cusp of failing the class fr but i went from a C to a C+ lol. i flopped in this class because for some reason i really struggled on the midterm and got an 80% when clearly the rest of the class found it very easy. i'm also not a great studyer so i didn't prepare as well as i needed to to slay on the final, but if you're a good test taker you shouldn't do as bad as i did. denis is actually a very nice guy and he can be funny during lecture so i liked him as a professor. there's a LOT of formulas to memorize and he doesn't allow a cheatsheet on either exam because he'd have to make the tests super hard, so master the material and do a lot of practice and you'll be fine. FUCK THIS CLASS I'M FINALLY FREE!!!!

As a person who mastered AP stats, scored the top 0.1% in Surro's Econ 11 class, and is a good exam taker, I still have to say THIS IS THE TOUGHEST CLASS I've had since I came to UCLA. 10% homework graded based on accuracy (EVERY HOMEWORK COUNTS, there is no such things as the lowest grade being dropped), 30% midterm, and 60% final. Note that he follows the curve strictly and he will curve up or curve down depending on the overall performance. For the lecture part, he basically elaborates every definition and then gives a very simple example--his lecture is very clear, but these examples are far easier than homework problems or exams. It's like he teaches you 1+1=2 but give you calculus problems in the homework. I basically relied on previous AP stats knowledge and Chegg solutions to help me learn, but if you don't have stats background or are not good at taking exams and calculating, then you really have to go to every discussion and office hours in order to understand how to do all sorts of problems. Practice exams are very helpful, and you can expect similar problems to appear in the midterm and the final. FYI: median for midterm is 29/30 (pretty sure it's similar for every quarter); and the final is hard--the median is 38/50.
