Strang's MIT OCW Linear Algebra is pretty good. Probably also needs the textbook.
John Tsitsiklis' MITx edx Probability intro course is probably the best course I've taken anywhere and better than anything I did in person at university. I didn't buy the text for this one though I probably should.
Came here to suggest Robert Sapolsky's class as well.
I would also add Michael Sandel's Justice: What's the right thing to do? https://www.youtube.com/watch?v=kBdfcR-8hEY&list=PL15D875D84... great course on moral reasoning, covers different theories of justice based on ideas from Aristotle, Kant, John Stuart Mill, John Rawls and many more, extremely well presented too.

Robert Sapolsky's Human Behavioral Biology Stanford lectures are well worth watching. https://www.youtube.com/playlist?list=PL848F2368C90DDC3D
