Objectively speaking, since this class was during COVID, it was expected to be more difficult than being in person. However, I am amazed by the fact that this year, this course was basically made HARDER simply because we were online. I personally felt that the exams were twice as more difficult as in previous years and I do not know if this was the implied intent from the professor but nevertheless, the exam grades showed that clearly. 2019 - like 89%, this year's first midterm was a 65%. For myself, this class was simply too fast and not useful in any shape or form but hey, I passed so that's fine. This class is a purely weeder course and by the end of it, since it was not clear as to how many individuals were able to pass with a B- or higher to stay in the pre-business economics major, I can objectively say that most of us despised the result. Best of luck to future fighters in this class as we bless you nothing but well wishes and lots of champagne and pizza.

I will now go cry and try to have a good COVID christmas.

The class in itself isn't that bad. His midterms and final were fair, and his sample exams give you a good idea of what will be on them. He talk a lot about pizza and sushi and Ferrari's and Bugattis. However, he curves down. This is the first class I have even been curved down, and he later told me that the econ department only allows a certain percentage of students to get A's. So while this class is fairly easy for a weeder and the averages on the midterm/final were around 85-90, he curves a lot of people down :/

This has probably been my best Econ class here so far. The professor is really good art explaining and is fairly engaging in lecture. The homework tends to be a little difficult but if you can find a study group you will all eventually discuss the assignment to find the correct answer. You don't really need the textbook if you attend all the lectures since he goes over all the material really well in lecture. For the midterms and final, I would definitely recommend practicing the past midterms and finals that he posts since he doesn't stray too far away from the ideas in the past exams. I found the material fairly interesting which helped motivate me to push through in the exams and homework, but it's not particularly the easiest class. I would, however, recommend to take it with professor Mazzocco.

Econ 11 is a pretty hard class. No way around it. Mazzocco does his best and in general is a nice guy and decent teacher, but if you aren't good at calculus like me this class will probably suck. His curve is generous which is good, but you will have to put in the time to understand the topics and figure out the problems if you want to get a grade above passing. The TA's for Econ usually aren't all that useful, so a lot of the learning in this class will come from sitting down and grinding through all the practice tests and extra problem sets he gives until it becomes automatic.

This class is going to be hard no matter who you take it with, so Mazzocco is probably one of the best people you can take it with. He curves very generously and gives you a ton of practice midterms and finals to study from that were usually relatively similar to the actual test. He's also pretty funny and a super nice guy overall, and his lectures were extremely clear. You have one problem set due a week, which I would definitely recommend actually doing to stay on top of the coursework. Overall, Mazzocco is your best bet to succeeding in this class!

I love Professor Mazzocco! He designed the class to be as fair as possible, and after a long string of professors who didn't bother giving us that courtesy, it was like a breath of fresh air!
First, the tests are all multiple choice and very fair. They are very similar to past midterms, which he posts online for you to practice. You also get a cheat sheet, too, and the grading scale is flexible so that it can only help your grade. He also gives out free points, basically, in the form of homework problem sets that he grades very nicely as well.
My TA, Carlos, was also great. He was always making sure we were following his lecture and was all around a great guy. Professor Mazzocco does have a slight accent, but I thought that as professors went he was always kind and engaging.
Slides and notes are posted online, and the textbook is unnecessary, so if you're smart enough you could technically get away with never attending class. I wasn't smart enough, but I enjoyed lectures anyways.

I don't know why people warned me that econ 11 is very hard. Mazzocco made it the most comfortable class I have taken so far at UCLA. HIS TEST WAS VERY CLEAR. My family had a big crisis since Oct 7th, and I got depression during the quarter so that I almost did not study at all. Mazzocco was very helpful in providing us all the previous exams for practising, but I only practiced one or two of them due to my dizziness. I think I was lucky to score well on the test because 1/ TA provided a useful note weekly to do the homework; 2/ both TA note and homework are handy to get the concepts well; 3/ this course is all about calculus math ( even did not use the cheat sheet in the midterms).

Thanks to Prof. Mazzocco for making this class very easy.

DO ALL THE PRACTICE EXAMS. I was really concerned about how I would do in Econ 11 because 1) I was told this was a difficult weeder class and 2) I got a C in Econ 1, making me think I wouldn't do well in this class. Thankfully, it actually went a lot better than expected. Mazzocco's lectures are very clear, just make sure you can pay attend through his accent and understand how to do problems through his somewhat messy handwriting on the lecture notes (which I often had trouble with). Overall, he seems to be a very caring professor, and is extremely fair on exams and his grading system. What really helped me get through this class was reading the lecture notes and the textbook (I did a lot of self-learning), and trying to do as much of the practice exams as possible, since they are EXTREMELY HELPFUL AND SIMILAR to what you'll see on the actual test. Work through the practice problems, use your TAs as a resource to explain problems you don't know how to solve, or, as what I often did, use YouTube! (That's how I often reviewed basic concepts and learned stuff like MRTS, calculating demand elasticities, etc). Econ 11 is NOT HARD - just put in the work, and you will see the results.

I have sort of mixed feelings about this class. On one hand, Mazzocco was a bad lecturer. I often had difficulty paying attention during lecture, and his accent often made him hard to understand. He also struggled to gauge how difficult to make his exams - the averages on the first midterm and final were around or above 90. That being said, he definitely wanted to his students to succeed in the class and provided us with the resources we needed to prepare for the tests. He also was fair about final grades - he didn’t curve anyone down just because the class did well on his exams. Overall, I would take this class with Mazzocco again.

Class is really easy so long as you study for the midterms and finals. Homeworks won't make sense until AFTER you hand them in.

If you just do the practice midterms and finals provided on CCLE with a methodical passion, you'll get a good grade.

Mazzocco is a funny guy. Really good professors. However, lectures are pretty much optional as he covers theoretical stuff for the most part in his slides, and the exams and homework as mathematical applications of this that you can easily look up.
