Ask HN: Is there something like teachyourselfcs for other sciences?

Hey HN, I am currently trying to learn biology and chemistry.

For computer science, there are a lot of great autodidactic curricula like teachyourselfcs.com which also show you open lectures by major ivy league institutions.

Is there something like that for other stem majors as well? I am really lost in combining concepts I learn by depth first searching wikipedia entries.
