ALEKS is a "learning tool" that somehow gets you to not learn, but throw away old information you already had. Oh, you're almost done with that set course and you got one question wrong? Back to the beginning, bucko. Don't understand this set course of questions? Who cares? Heres this set of hastily scribbled notes that you can try to understand, but you probably won't. Overall not a recommended website. If you are going to be teaching a class, avoid ALEKS as a website.
