Thanks @CalCUStanford ! I am currently doing lots of research in autonomous systems and how to optimize drug testing to pipeline the vaccine testing process. 
Cool!
@GoBears2023 : If possible, try to take Prof. Samuel Chiu of MS&E probability class. It’s structured in a very unique way (i.e., thru team project and challenging yet interesting case problems, etc) for you to learn the concepts of probability. I don’t know if he’s still teaching, maybe retired. Or simply get his textbook from the department. I would love to get one next time if I go there. Anyway, enjoy your time @Stanford! 
Thanks for the advice! I’ll reach out to him!
