This was overall a very tough but useful class. This class builds off of the material we learned from 103 so it is very important to have strong R skills as you will be doing group projects using R. The group projects were tedious but are mostly graded based on completion. Since this was the first quarter having exams in person, we didn't have to code on exams but instead they're mostly conceptual, some calculations, and some R code interpretations. Overall a pretty good class and prof rojas is very helpful and open to answering questions.

Professor Rojas explains concepts very clearly and makes sure to answer all of his students' questions in class, even if it takes a while. Because of this, I think he's a pretty great instructor! However, I do feel like he spent waaay too much time explaining super simple concepts and waaay too little time explaining some of the more difficult concepts. There is very little work required for the class, but if you want to have a strong understanding of everything I would recommend doing all the chapter readings. For the most part, the exams are straightforward (they're all multiple choice), but the second midterm was fairly challenging in my opinion. The overall class structure is a bit boring, but the content itself is actually pretty interesting if you're someone who really likes connecting intuitive ideas to the real world. Overall, I definitely don't regret taking Econ 1 w/Rojas!

This is really the hardest class in the econ department. Imagine Econ 103 x 10 for level of difficulty. Professor Rojas is very inspiring and engaging, although the materials are hard and he’s a strict professor, he still managed to make me like the class way more than I thought I would. The key to do well in this class for me was practicing coding and understanding the theory enough to be able to code and understand the output. Professor Rojas expects you to know a lot, so if you didn’t take econ 103 with him, let him know so he can provide some sort of R workshop (which he did for us) or his lab notes from 103 so you can catch up. Otherwise I recommend learning R using datacamp or something like that to get ahead. Always take advantage of his office hours because he’s very patient, and he truly wants his students to succeed. I asked a lot of stupid questions but he would try a lot of different ways to explain. The skill set I learned from his class is honestly the most useful out of all the econ classes i’ve taken due to the coding aspect.

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.

This class is pretty easy for a math class. I really appreciate how Professor Rojas isn’t one of those professors that makes exams much harder than his examples and practice problems. There’s homework in this class but it isn’t graded so the workload’s pretty small. I’ve had Rojas before and I admit his style of teaching is not very interesting. However, he is literally the perfect teacher for this class. There are a lot of formulas and he explains them really well. Also, I got a 72 on the first midterm and still managed an A in this class. So his curve’s pretty nice.

Rojas is bad with emails, he will only reply once. Half of his test questions are from Mindtap. Sometimes if you find an old exam he may reuse some of the questions. His lectures are pretty clear but super boring. He uses the whole time. He often asks if you have questions and then moves on immediately. He lowkey does not want your questions. We didn't even finish the content on the syllabus or even the final by the last lecture. He has a very boring tone and his examples and engagement in the class is okay. All his tests are multiple choice so there is no forgiveness. Discussion isn't that helpful if you get the concepts because it is conceptual questions, while the tests are more questions trying to trick you, as MCQ does. It is possible to do well and not learn a lot, as it is possible to understand a lot and do poorly. He only curves if the final class average is below a B. It is easy enough if you do Mindtap (mainly just the A+ test prep), and skim his slides. Lecture is a waste of your time if you only care about your grade because if you practice for half of lecture time you are way better off class wise.
