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.

Great professor! Tests only what he teaches (textbook truly is optional, not an "optional unless you want an A"), pretty clear at delivering the content, and posts all the practice material you need (aka all past exams on CCLE). If you know the main concepts of the class, a B at the very least should be doable. However, since he has changed the test to be all multiple choice (as opposed to just 30-40% of it), averages have risen to 80-90%, so expect essentially no curve. Because of that, I would say know the details because that can be what differentiates the As and Bs since there's very little room for error.
Unorganized pointers:
- You need to remember almost no prior econ to do well
- Mass majority of the tests are calculation based
- Concepts are still important for that last 10-20% to push into the A range. You don't need to know the proofs for the formula, but the conditions for which they are true or the (VERY BASIC) intuition behind them will likely be tested
- Most tests had 2-3 questions on the minor details. This still makes up nearly 10% of the test. Don't study too hard for these - instead, just write down all the formulas (even if you think they're insignificant) on your cheat sheet. In my experience, you'll have plenty of time on the tests to play around with the formulas until something matches an answer.
- My main error was finishing too fast - try to stay as long as you can even after you finish to check your answers. Careless errors made up over half the points I lost, and with little to no curve, this can make or break your grade.

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.

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!

Grade consists of 2 midterms, 1 final, and weekly problem sets. He drops your lowest midterm score. He posts all the old midterms to use as study guides, very helpful. He allows a cheat sheet on the exam. Lectures are all recorded, and slides/notes are posted. I've never touched the textbook, his material is enough. Class is math-heavy but fairly easy if you don't fall behind and study the material he posts. Also, attendance for discussions is not required. He also claims to be generous with the curve.

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.

Mazzocco was a genuinely nice professor and he seemed to really care about the students and the material in his class. He provides a lot of previous midterms for practice and make sure you do every single one beacuse his tests are extremely difficult. Because this quarter was online all of his lectures were consistenly longer than the actual time allotted for the class. He is always thorough with explanations but he goes over many derivations that just aren't necessary at all for his exams. I consistently scored below average on both midterms but managed to do well on the final, so I got a B in the class. If you take this make sure to utilize the practice midterms and any extra problems that him or the TA's provide. The curve was pretty generous, considering most people didn't do well on both of the midterms. He says the midterms are open note and that's a supposed advantage that students during covid have over previous econ 11 students BUT there is absolutely no time during the tests to be looking through all of your notes considering how many questions are asked in such a short amount of time. If you take this class be sure you are extremely well prepared for the midterms and final, cause that's your entire grade.

Based on the pre-covid reviews, I thought this class would be a breeze compared to other professors. However, he gave us twice as many lectures (just b/c classes were online) and personally, I had a hard time understanding his lectures as he doesn't teach the stuff you REALLY need in order to do well on the test. I had to go to my TA office hours and ask him about everything to later learn about other concepts that were not even mentioned in the lectures. As for the tests, they are definitely way harder than the previous years. He will also have TA's monitor you taking the test on zoom.
