He's a really good and engaging lecturer of material that can sometimes be very dry. Slides are posted after lectures, which is nice and very useful for the homework, but he never uses the textbook, so save yourself the $100. Homework is fair and not too challenging. Exams are also fair, but all three were fairly challenging, but Mazzocco posts every exam from the last six years for you to prepare with, which is really useful. He'll also drop the lowest midterm if you do better on the other two exams. Mazzocco's also very accessible and helpful during office hours, and for some reason, almost no one shows up, so you're able to talk to him one-on-one. Having a good TA is also very helpful. I had Vitaly Titov, who was excellent, though having gone to all of the TA-led review sections, that might've been an exception. One last note, the class is extremely competitive and curved, so make sure you don't fall behind. Overall, Mazzocco does a good job teaching, and is a good choice for Econ 11.

BEST PROFESSOR EVER! Engaging, smart, helpful, clear... everything you'd want in a professor. TAs--for the most part-- were really good too!

This class is difficult in general. Teacher uses slides but they don't necessarily help with homework since the slides are very generic, but still contribute. Try to get a good TA because that's what will really help you in the class. My only complaint would be the final. He gives previous finals (and midterms) to study for the tests from every year since 2010, however the finals previously given were SO much easier than the one given this quarter. Midterms consist of 10 conceptual multiple choice and 3 free response math questions with multiple parts. Yes there is a curve depending on how the class does as a whole. He will drop your lowest midterm if you do better on the final and the other midterm.

Textbook is useless, don't get it. Mazzocco reviews all the calculus you need to know during the first few lectures which was very useful for students who have never taken multi-variable calculus before. I had Richard Domurat as a TA and he was extremely helpful, would recommend. All you need to do to study for exams is review the past exams he posts online.

Midterm One Average: 82%
Midterm Two Average: 68%
Final Average: 69%

I got an A on this class.
I agree with the poster below me, Alessio Galluzzi was absolutely terrific as a TA. He made a huge effort to help the students. Mazzocco was also pretty good. His lectures were decent. In my opinion, his tests are optimal for students who understand the intuition behind economic concepts.

As for the slight about international students from the poster below: whose academic inadequacies does your comment really display ?

Mazzocco makes material fun and interesting. His tests are pretty hard as expected in this class and a really annoying thing is the fact that the majority of these econ classes are international students who are extremely good at math. I am not being prejudice or anything, his class is full of students who are prepared well for his class because they have already taken crazy difficult math classes in their home countries so they make the average grade higher.

Anyway, he grades really fairly, IF YOU CAN, TAKE GALLUZZI AS A TA!!! he is seriously amazing.

My advice is, do poorly on one midterm. Do well on another, because he drops the lowest one AS LONG AS IT'S LOWER THAN THE FINAL. So do poor on one midterm. The first midterm was harder than the second, but I think thats just because we didn't know the material as well.

I got a D on the first midterm, a C- on the 2nd, and ended up with a B- in the class, so he does curve very generously because he really does want everyone to do well.

He told us all these funny stories in class which made lecture fun but whats the point of fun lectures when his tests are ridiculous and everyone struggles ?
I retook the class with Prof. Cantu Garcia in Spring and got an A.
Avoid at all costs !

I took Econ 11 with Mazzocco in Fall 2014. Let me start of by saying Mazzocco is a nice guy. But the problem lies in his breaking down of concepts. He makes them seem extremely simple in weeks 1- 3 which does not prepare you for the midterm at all. Most people in my class got screwed over on the tests because they were so much harder than his lectures. This class destroyed my GPA in a sense as it also underprepared me for econ 101 and 102. I came into Mazzocco's class as a 2nd year with a 4.0 with As in Math 31A and 31B but my gpa was ruined by my 3rd year due to Mazzocco's class and the after effects.
I would suggest taking it with Sproul or Garcia or just waiting for a quarter as Econ 11 with mazzocco is a bloodbath.
Avoid this class especially if you are an econ/ bus econ or math econ major.

Definitely don't take mazzocco for econ 11, took him last year and learned nothing. he is very difficult to understand, which makes taking econ 101 very difficult given that you didn't understand econ 11! Cantu Garcia is a much better professor when it comes to clarity and learning. i got a C- in mazzocco's class then re-took econ 11 with Cantu Garcia and got an A-.

Mazzocco is definitely my favorite professor in UCLA so far! His lectures are clear, organized, and interesting. If you pay attention in class, do the practice exams, and attend discussions, then you should do well on the midterms and final. I thought Econ 11 would be hell for me but it turned out to be great because of Mazzocco!
