Brilliant
Instructors
Outlier’s Precalculus course is taught by Kelsey Houston-Edwards, a charismatic instructor who’s renowned for her ability to clearly communicate complicated concepts, including for shows like PBS' Infinite Series.
Our guest lecturer, Po-Shen Loh, is a popular math YouTuber and professor at Carnegie-Mellon who has a knack for connecting math with everyday life in the most unexpected ways.
Hand-picked from dozens of candidates, we selected them for their passion for numbers, and their uncanny ability to bring big mathematical concepts to life.
