Professor Olafsson is very thorough with the material. He really values his students and wants for them to do better. Extremely smart guy! And has a beautiful smile :)

Took Olaffson's PSTAT 109 in the summer session A, overall, I felt he is a great professor, he offers a lot of office hours, as well as a lot of practice problems. MAKE SURE DO ALL THOSE PROBLEM SETS, because he will put one of the questions on the exam.

Very knowledgeable professor. Lectures are easy to understand. Generous with his time outside classes. strongly recommend.

The course is not easy if you are taking it for letter grades. Put effort and work hard then you will be okay. He is really accessible outside the lectures. A good teacher, after all, he knows the materials well.

He is not a good teacher, his lecture slides do not help in the slightest bit and I don't think he understands the concept of explaining things. I hate this class and I don't like this professor.

Good teacher. Laid-back and presents the information clearly. Tests are difficult and my grade suffered because I took this class over the summer with too many other classes; if you have the option, don't take this class in 6 weeks.
