This class is moderate. The concepts are slightly intuitive, slightly need memorization. With Rojas, you don't really need to go to lecture because he reads off the slides but I kinda recommend it because it's easy to fall behind i the class. He does like a chapter and half per week and it's easy to forget about the class. I mostly read the book and that was easier to comprehend. Just skim the slides to make sure to didn't miss any specific info bc his tests are kinda nit picky. The midterms are only 25 questions so if you miss a few, it's already in the B range. The mindtap program is really useful and important. I shared mine with 2 other people which made it go from like $120 to $40 each and we didn't come across any problems with multiple people on at a time. The final is 75 questions so is worth a lot more than the 2 midterms and my TA said doing good on the final is more important.

Professor Rojas is, hands down, one of the best economics professors at UCLA. The class starts out with simple concepts, but ramps up the difficulty after the 1st midterm. Make sure you know how to take integrals and derivatives. Rojas doesn't really go over these in class, but Math 31A/B are prerequisites, so you are expected to know how to perform basic calculus.

Your grade in this class is 100% dependent on exams (25% midterm 1, 25% midterm 2, 50% final). Midterm 2 is not cumulative, but the final is cumulative. I received an A in this class with 14% above the average on the 1st midterm, 25% above the average on the 2nd midterm, and 13% above the average on the final.

Best of luck to everyone!

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.

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.

Rojas is nice... but he's overrated. There's no reason to delay taking 103 just to take it with him. Like others have said, his tests are similar to the practice exams and homework problems that he assigns. However, his tests are really, really time crunched.

One of the worst experiences ever. Professor Rojas spends forever on painfully simple concepts, even making many mistakes while doing so. In fact, he spent so much time on basic set theory that he cut out maximum likelihood estimators from the course, which was arguably the only difficult part of Econ 41. Going to lecture was the biggest waste of time ever--Rojas just throws some definitions at you and then does the most simple examples ever. Lectuers were boring and the class overall doesn't require much thinking at all.

Rojas is a great professor. For the most part he explains everything clearly during lecture and gives lots of examples. He may go a bit fast during lecture sometimes, but that is my only complaint. He is very helpful during office hours and seems to really care about student learning. I found his final to be a lot more difficult than the midterms, so be prepared for that.
