Stats 116 Stanford -
STATS 116 is a introduction to probability. It’s not a blow-off, but it’s also not a proof-heavy torture class. If you put in the hours and keep up with calculus, you’ll learn a huge amount that pays off in later stats/ML courses. Most students leave saying: “Hard but worth it.” Last note : If Persi Diaconis is teaching, expect more combinatorial magic and card tricks in lecture. If Candès, expect more connections to signal processing and high-dimensional stats. Both are fantastic.
