Reviews of professor Jason Xu

Rating: 5.0/5, difficulty: 5.0/5
Rly difficult class conceptually but you will definitely succeed if you keep up w/ content and review constantly. Jason is such an amazing guy, rly helpful in office hours. He posts recorded lectures from past years so I relied on those a lot. Midterm was rly difficult, everyone got bodied, then he lightened up on the final (take home format)

I was a bit nervous about this course coming in, but it wasn't bad at all. Jason's lectures were generally very helpful, and he's always willing to clarify explanations and answer questions. Weekly HW was sometimes challenging but overall pretty fair. Two midterms and final had average scores around 80% with questions based on lectures and HW.

Full honesty, probably the best class I ever took at Duke and almost entirely because of Jason -- if you're not sure if STA is for you, stick it out through this class. The math is beautiful (even if you're not a math nerd), and Jason's one of the best lecturers at Duke bar none. Definitely not an easy class but you won't regret taking it.
