I think calling OCW just a data dump is a little bit too over the top. I am following their Linear Algebra course ( https://ocw.mit.edu/courses/mathematics/18-06sc-linear-algebra-fall-2011/index.htm https://ocw.mit.edu/courses/mathematics/18-06sc-linear-algeb... ) and so far it's been really great. There are questions and answers after each lesson, you even get exams and their answers so you can test your progress. Also the youtube comments for some of these classes seems to suggest that a lot of people are really thankful for the content.
