What is interesting is how they built their classes. They went out and scoured the cloud for material, collected, it, and organized it into classes. I really think is the new "textbook". I glanced at some of the chem stuff and it seemed reasonably good.
This is what I'm building for my AP chem class with links to text. I also link to tutorials and videos however but I only have one class, not a whole major.
As usual, they had more bio than chem material. They also have humanities and social sciences.
