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.

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!

Professor Rojas has an incredible amount of education (double Doctorate holder) and tries to make Econ 41 as frictionless as possible. The first midterm is extremely doable, and each test thereafter is more challenging (so do tons of practice for the first one to cushion the others). Not the most approachable professor since he always had class after lecture, so make sure you find a good TA.

Professor Rojas never had the decency to respond to any of my emails. I always had questions and he never helped. He was useless, my TA was fantastic.

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.

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.
