I currently use MyMathLab in my classes, but was curious if there are any open source alternatives? I’m approaching the point where the text book (and all the other publisher content) is superfluous. There is just so much good ‘how to’ material on the web. The one thing that makes MML indespensible for me is the algorithmically generated questions for homework, quizzes, and tests. I know there are a lot of other publisher equivalents, but I’m looking for something open source. Let me know if you have any leads.
