Reviews of professor Brian Schaffner

Rating: 3.0/5, difficulty: 3.0/5
Not an interesting class. Lecture-heavy and a lot of readings. The grading for exams is also not clear. I did way worse than I was expecting. Schaffner is also very picky about small things like participation grade. I regret taking this class.

Schaffner is a cool guy, the class is interesting if you're interested in data science plus you learn R. You don't need it but taking an intro stats class would have helped. Weekly problem sets and quizzes, as well as a tough midterm and final and group research project. Finding people to do problem sets with helps a lot. I feel accomplished
