Khan Academy but for University

The official [Khan Academy](https://www.khanacademy.org) subreddit. A forum for discussion about Khan Academy, and learning in general. Khan Academy is a not-for-profit with the goal of providing a free world-class education for anyone anywhere. Hi All! I’m no where close to completing all of Khan Academy but I’m just wondering if there’s a Khan Academy like site that will provide knowledge to an equivalent undergraduate degree in math, engineering and/or physics? If there isn’t what the best way to self study it all without going to university? Textbooks? Lecture notes? Other online resources (MIT course-ware or something like that)? Thanks and have an awesome day!!!
