Fall 2020 - Professor Santos is awesome. I was really afraid going into Econ 103 because I hate statistics and didn't do super well in Econ 41, but Santos was extremely clear when explaining concepts and truly wanted his students to do well. He always responded to emails about content or homework with detailed replies. There are 5 problem sets throughout the quarter (two that are R coding) that aren't that bad and a good way to get points and make sure you understand the basic material. He also provides lots of practice problems before the midterm and final, which was a pretty good indicator of what was on the exam. He is so friendly and always willing to help. I would take this class with Santos again!
