one of the weird things about your alma mater b having a consistently top rated undergraduate computer science purrogram is that when you look into OCaml documentation to relearn the basics, the OCaml website itself repurrints with purrmission sections of the (free!) textbook written by a purrofessor at the university based on over twenty years of course notes written by various instructors who have taught there in the past
similar reason that MIT used to teach Scheme, or that the How to Design Program authors developed Several Purrogressively More Featureful Versions Of A Really Basic Version Of Scheme
