Rojas was a very good professor. For someone who doesn't necessarily know the concepts of Econ, he explains it thoroughly. As for me, I knew a lot of Econ from merely taking (not AP/IB) an Economics class offered in my high school. His midterms were way too easy everyone did too well. His final was a LOT harder, though. I recommend going to lectures because he's just such a great professor, but don't feel too bad if you miss his lectures because his powerpoints come online. Just make sure to take advantage of the textbook as the textbook in itself is the source of most if not all the information. I didn't go to about half the lectures because I couldn't wake up, but I really took advantage of the book and was able to manage an A.

Very fair class. Midterms and final were all multiple choice but the final was unexpectedly more difficult than the midterms. Only downside is that you have to buy Mindtap which costs like $130 just to submit weekly homework. I came in with zero knowledge of Econ and ended up getting 24/ 25 and 25/25 on the midterms. Just dedicate time to understanding the concepts and doing the homework with purpose and I guarantee you'll do well ( unless you absolutely hate econ) It won't be like one of those classes where you studied hard and dont see the results you expected: what you put into the class is what you get out. You dont necessarily have to go to lecture as he just reads off the slides, you literally could just read the book and take notes and only show up for the midterms and final and pull off with an A . I went to every single lecture but that was because I was a naive freshman :)

This was my lowest grade at UCLA thus far but I do feel there was more I could have done to study for the tests. I scored about 10% below the average on the first midterm, average for the second midterm, and average for the final, so the curve helped me out somewhat. The practice problems and practice finals are pretty representative of the exams but you definitely need to thoroughly understand the material to do your best. Rojas is extremely helpful at his office hours and is a very approachable guy. Despite my grade, I'd recommend him.

I strongly recommend Professor Rojas for 41, as really tries his best to give students ample opportunities to learn and practice the material before Midterms. That being said, this class is very difficult, but manageable if you do all the work in a timely fashion. Homework isn't graded, and there are 2 midterms and a final exam. He provides a formula sheet on the exams, which is not common for other 41 professors, but his questions may be more difficult because of that. You definitely need to know how to apply the concepts to do well in this class. Lectures are all done on the chalk board, so you need to come to class to have access to the information.

Econ 1 with Professor Rojas is a tough but fair class. You can do well without reading the textbook, however, you need the MindTap access code that's included with the textbook to complete the homework, and many homework questions come directly from the textbook reading. The homework is online multiple choice, and you get two tries, and also one check for correctness for each question, so it's hard to not do well. Professor Rojas's lectures are straightforward, and he encourages questions, although he does move fast. The two midterms are easy, but the cumulative final is significantly harder. Overall, an A is attainable if you take time to thoroughly do the homeworks, and study for the midterms and final.

Rojas is a great professor. He really cares about his students well being and if they understand the content. He taught straight from slides and lacked a little clarity towards the end of the course, but it wasn't too bad. Make sure to do his weekly homework and readings on mindtap which will help you understand the material. I didn't go to class week 9 and often was distracted during his lectures but still got an A+. 24/25 on both midterms and a 58/70 on the final. He is a dry lecturer so make sure you stay awake.

I felt he was a really concise teacher and though us exactly what we needed to learn.

Econ 103 is a class a lot of people leave last, and Rojas is usually the recommended teacher for the course, but the class itself is complicated if you don't have a solid understanding of stats. I had a horrible experience and deadbeat professor for 41 and still managed to pull through. The curve was helpful, but then again it can go either way with these things.

I recommend that you download all the slides from the lab lecture and the TA sites and go over them three times a day--maybe after every meal? Rojas is an excellent teacher; the lectures were at a good pace until the end where he tried to squeeze a whole chapter and a half and then used it for the final! Otherwise, it is a fun class if you enjoy math and stats, but I would use every source you could get your hands on!

Rojas has a specialization in statistics, which is why he is really great for teaching this class. If you had a hard time in Econ 41, then it'll be difficult in this class too because in delves into the theory and practicality of the topics from 41. I had a solid foundation in stats and therefore didn't have much trouble with the subject matter. 103 heavily focuses on regression and variable testing, such as t-tests, F-tests, chi-tests, etc. Rojas does not use slides for the main lecture, rather goes at a slower pace by writing it all out on the board. While the lecture notes were clearly provided, the symbols and equation styles might make it hard to understand, however, if you do your hw, you will understand where everything is coming from. You do not need to memorize any equations because we are provided with a formula sheet that includes nearly everything you need to know. The exams test whether or not you know what and how to use a particular tool, and summarize the significance of it - therefore, the word problems were fairly decent if you did your hw and practiced on some practice tests. The multiple choice questions mostly test theory, and are a bit more difficult, but certainty not impossible. Two midterms (25% each), had 5 word problems, 5 MC. Final (50%) had 10 word problems and 10 MC. The lab lecture focuses on Stata tools and uses for the topics learned in lecture. Stata is easy to learn if you go to discussion and work it yourself along with the TA, and use the Stata book for hw guidance.
