DO NOT TAKE THIS CLASS IF YOU HAVE NOT STUDIED ECONOMICS BEFORE. Frankly, there is no way you could survive. Its not because of Professor Rojas, but the fast paced nature of the quarter system. You learn the fundamental concepts of economics within a week or two, stuff that is generally taught over the course of a year in high school.
If you have taken economics before however, this course is not too bad. The first 4 weeks of material is extremely easy (concepts like supply and demand, opportunity cost, etc.), the next 4 slightly harder (trade, tax, etc.), and the last 2 are tough (competitive markets, calculating costs). Professor Rojas is overall a friendly person and a decent lecturer. He basically reads off his slides the entire time but since they're fairly detailed and self-explanatory, I didn't see much of an issue with that. He's always willing to stop and help students understand concepts better if they don't get it. I would strongly recommend taking this class online if possible. Mine was entirely online and it really helped a lot The grading scheme is a little tough with :

Homework - 15%
Midterm 1 - 20%
Midterm 2 - 20%
Final - 45%

So your grade pretty much depends on your final. Homework is an easy 100 as all of the answers are on quizlet, and you can use a checking feature on your assignment to verify if your answers are correct.

Discussions were optional, and went more in depth on how to calculate or find certain values based on graphs or tables which is generally what the format of the tests are, so I would recommend attending it. My TA, Palleja, was great. He recorded discussion sections at the beginning of the week and then posted them on Canvas, so I never had to physically attend a discussion.

Overall, not a bad class. If you don't have to take it, I would avoid it, but if you are an Econ major, this should be an easy class for you.

I really liked Professor Rojas. He was very clear and there was not much homework. I took this class on Zoom and still I felt like it was a pretty engaging class.

this class was ok. i took ap macro in high school so this was just a review for me. the lectures were BORING so i never paid attention and just read the textbook instead which was way better. all the weekly homeworks/midterms/final were on mindtap (online but i think that was only for this quarter)

This was a pretty easy intro to economics class. The course material is very similar to AP Microeconomics if you have taken that before. Rojas was an organized lecturer and really chill professor. All of his slides consisted of material straight from the online book that we used. Class was very straightforward, and homework assignments were fairly easy. The two midterms and final were all multiple choice and were very similar to the homework and practice problems. Exams were also open note and taken online. If the class does poorly on exams, Rojas will curve upwards, but I am pretty sure that everyone did pretty well on all of the exams during this quarter.

Discussion sections were not that useful to me, but they were helpful if you had a question or struggled on a topic. I only went to my discussion a few times, but TA Dom explained everything with clarity, and I recommend him.

i really like professor rojas and i took this class because i really enjoyed taking 103 with him and i did well (i took 103 before the 104 prereq came out) but this class was definitely really challenging for me, and i wish he didn't reference his 104 slides so often since there are students who technically did not take the course yet (or never will!) Admittedly, I definitely didn't take full advantage of office hours and going to class since things were online so i wish i did that more, but he did curve the final grade.

I enjoyed Rojas' lectures. I am an econ major so I enjoyed to be able to have a class that is more applicable to real life situations than theory. I attend school full time and also work 30 hrs per week which makes the whole school schedule difficult to balance. Thus, any student who puts a little bit of effort will be able to get a good grade in this class. Like the other person mentioned, exams are very similar to practice exams/homework problems. It is a little pressed for time (practice to solve the problems fast). The MC questions are a little more conceptual. I think that he was one of the best professors that I had so far. He actually teaches the material.

If your read the text book it basically the same material as his slides, unlike other classes their is no room for error on the exams because the the only thing being graded 2 midterms worth 25% each and 50% for the final. he said that if we studied using mindtap we would be well prepared for the exams but the practice exam mindtap generated were way easier and less application based than his exams so at times it felt like i was just memorizing answers rather than learning how to apply the class content. I feel like many student would've felt more prepared if we had homework assignments so that we can get more practice or even extra credit opportunities, as not all student are good test takers.

one word, Mindtap.

really nice and smart prof but he didn't even give us a practice final... and didn't inform us we weren't going to be given a practice final until someone emailed their TA and told the rest of the class. midterm was completely unlike the homework. notes are full of information that isn't going to be tested. the project (a 30% of your grade) is graded on completion (thank god) because our TAs (god bless them) tried their best to help us and pretty much gave up and told us to use chatgpt to check our code

This class gave me mixed emotions. I think it is a must-take ECON elective because of how much I learned through the quarter. It is by far the most useful, interesting, and informative ECON class I've taken at UCLA. The reason emotions are mixed: it's a ton of work. There is a homework or project due every Friday (besides midterm week) and it takes about five or six hours. I don't know if this is typical, but the homework and projects were basically graded for an honest attempt (I think the average score on all of them was like a 95%). The exams are tough, but it seems like an incredible amount of partial credit is given. Our midterm median was an 81% and the final median was a 72%. I think a slight grade boost/curve was applied at the end of the quarter (maybe an extra 3% or so?). Also, a note on Rojas: he gets a lot of negativity for how he teaches ECON 41 (which I did not take with him), but I thought he was a really good prof for this class. It's really easy to slow him down in lectures and go over things, he explained everything pretty well, gave examples, etc. Overall, if you are ready to work, take this class.
