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.

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.
