Professor Rojas is so boring!! His lectures are not engaging and he isn't very clear on challenging subjects. His tests are also very hard.

AVOID ROJAS AT ALL COSTS!!!!!!! HORRIBLE BUT HORRIBLE LECTURER, HUMAN BEING (and class)... Every exam keeps getting harder and harder and the final is 70 QUESTIONS LONG...
However if you DO have to take it and rojas is your only choice then BUY mindtap even if its not required. Midtap has a lot of multiple choice questions per chapter (like over 100 questions) and you can use them to practice for the exams.
He used to make mindtap mandatory but now its not so really buy it and practice practice practice EVERYTHING!!!
His final IS CUMULATIVE so beware and practice a lot especially the 2nd half material!!!

Professor Rojas was an extremely boring lecturer. If you take this class, just review the slides on your own time and don't bother going to class. He lectures painfully slow, and spends much longer than is honestly necessary to learn the content. He also requires that you purchase MindTap.

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.

Definitely try to take Econ1 with Rojas if you can! He's a super kind and helpful professor, although a bit dry since all he really does is read off his slides in class. That being said, there's really no harm if you miss a few classes since everything will be on the slides he posts. He gives sample midterms and finals before each exam and he's extremely helpful if you go to his office hours as well. For this quarter we did not have to buy Mindtap which definitely saved a lot of money since I just read a free pdf online, but also made it so that you really need to do well on the midterms and finals (25, 25, and 50% of your grade respectively) because there are no other assignments in the gradebook to bring your grade up. But overall as long as you carefully study the powerpoints and don't fall behind the test are extremely straightforward. Highly recommend this class.

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.

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 legitimately one of the best professors at UCLA. He is very neat and organized during lectures. His tests are extremely fair. All of the material comes straight from the book. If you read the textbook and understand it, then you will do very well on tests.

His midterms are a bit time sensitive and a lot of the problems require tedious work. However it is not a difficult class. I've noticed a lot of people complain about not doing well, but then they admit they never open the book. As a math major I think this is a bit ridiculous. If you want to do well in the class open the book and read it. Rojas has less than 3 hours a week to cover the material he needs in a 400 person lecture hall. You can't expect him to explain every detail.

You don't really need to go to lecture, or lab, or learn STATA (outputs on exams are pretty common sense once you read the book). Great class and very useful.
