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.

Professor Rojas is very clear in his lectures and slides. He has a very good TA team so even if he is not available for office hours, his TA's are. He gives lots of practice midterms and questions and they are pretty similar to the actual tests. Not the easiest class but definitely the best professor to take it with.

Professor Rojas's 103 is overrated. He was good at explaining the class material for sure; however, he did not make any additional effort to accommodate the large-class size. There were roughly around 360 students in the class, but he had an hour and a half I think? office hours per week. There were many students coming to his and other TA's office hours, so it was very difficult to ask questions and learn.

Also, TA's graded exams pretty darn strictly and weirdly.. On the midterm, I multiplied -2 instead of 2, and I got -7 off for that.. I talked to the TA who graded it and she would not give me anymore partial credit than 1 (so I didn't take it)..

But I would say, still, the workload is pretty light and curve was generous... Only two people scored above 90 on the final, with highest score being 92, so I would say that the exams were not specifically easy.

Econ 103 and Econ 103L are the classes using Statistics knowledge at Economics Department. The good thing to learn Econ 103 with Professor Rojas is that he has a very descent knowledge of Stats and often make the points very clear to non-stats major students. Besides, he is very polite and helpful both during his class and his office hours. He likes to make sure every students are clear on the subjects. If you attend his lectures (highly recommended, very clear) and do the exercises, you should be find on the midterm and finals as they are pretty straightforward. Highly recommended :) Professor Rojas is the BEST Professor ever! I would love to take more classes with him.

You do not need to go to lectures for this class because he reads off the slides. The midterms are quite straightforward but the final is tricky.

Rojas is a great professor for Econ 1. Lectures are helpful and informative, and the midterms aren't bad (the final was pretty hard though). Mindtap was pretty helpful, at least in my experience.

Prof. Rojas was an extremely boring lecturer. He took forever going over very basic concepts, and didn't end up going through the entire syllabus (skipped the entire section on heteroskedacity). Overall, the class was extremely easy--no assignments, only two midterms and a final, all of which are fairly straightforward and similar to what was covered in class. The recommended textbook problems are significantly harder than what shows up on actual exams. He's very boring and wastes too much time answering student questions, but if you want an easy A, take this class with Professor Rojas.

This lab lecture for Econ 103 is just as bad as the normal lecture. It's taught in STATA, which is probably one of the least useful languages. That being said, Professor Rojas allows students to use other languages if they wish (including R or Python), as long as you can understand STATA output, which isn't too difficult. Professor Rojas makes it clear what components of STATA programming you need to be familiar with, and after a quarter of never touching STATA and using R instead, it was still extremely easy to have the STATA comprehension ability required on exams. Professor Rojas is probably the best professor you can get for this waste of time class taught in a waste of time language.

The midterms are fair if you pay attention to the slides and read the textbook. However, the professor mainly reads the slides in class, so if you understand the material you should be fine. The professor seems nice and answers question in class should you have any.
