This is by far the most interesting and useful economics course I've taken at UCLA. Be aware, aa majority of the class drops out throughout the quarter. The quarter started with 145 students and a full waitlist and only 69 were left taking the final. There are a couple of reasons why.
First, the course description says, "Preparation: familiarity with data analysis software (e.g., R, Excel, MATLAB, Stata) and/or programming experience." This is not a suggestion. No, opening stata once and copying down 10 lines the professor gave you in 103 does NOT count. Most people dropped because they have never done any programming before and could not keep up with the pace. It is crucial that you take at least one programming course before. (If you want to use Stata from 103, actually learn it). Rojas gives you a homework week 1 in R that will generally weed out most of the class who takes a week and can't figure out how to upload a dataset.
The course has 1 midterm, 5 homeworks, 2 projects, and a final.
It is a lot of work. You learn a lot. If you are an econ major, this will probably be by far the most difficult course you will take at UCLA. If you are a math major (most of the class had a math/stats/ physics background), this should be easier than most of your other classes.
Most people do well on hw/projects. The midterm and final are very difficult. Averages were around 68. The course itself covers a broad range of topics. He will test you on topics barely mentioned and push you to really learn a lot on your own. Your success in the course depends on how much work you are willing to put in outside of class. The curve is very generous. I think it's misleading to think this is an easy course because of the grade distribution. The people left at the end are all very smart and willing to work hard, and Rojas rewards that.
Overall, I really recommend this course. Besides Econ 103, I think this is one of the only Econ courses that can actually benefit you in a career. You'll have to put in a lot of time and effort, but I think it's really rewarding. Whether you should or should not take this class really depends if you're here to get easy A's or want to learn valuable skills that will require a lot of time and hard work.
