Test is not easy but grade will be curved. Clear lecture notes will be posted on gs. He is handsome.

Petersen gives great lectures with good notes. He posts all his slides and recordings on gauchospace, but does give pop quizzes. He is very passionate about the subject and cares for his students.

Great lecturer. Posts his notes and voice recording online so lecture isn't mandatory, but I still recommend going. Responds to emails and accessible during office hours. Conceptually, material isn't too diff and although the midterm felt brutal, there was a curve. Final was cancelled due to virus so can't speak to that. Easy on the eyes too

Lecture isnt mandatory but he does give pop quizzes here and there (sometimes he tells you, sometimes he doesnt) but theyre open note so if you show up to lecture and take notes, you should be fine. Material is very dense, and proof heavy, but he gives you the formulas youll need for applying it. If you go to class and study you should be fine.

I like how he teaches the class. This is real statistics. Though one can just tell you all the things and let you practice like robots, in this class, you will have chance to practice and understand by yourself. It is hard, but I think it is really good experience to prepare for some practical things.

Petersen gives clear lectures and it super friendly and approachable. Definitely one of the better prof's in the stats department. The material for 126 is pretty much the same no matter who you take it with, so I'd recommend Petersen.
