Explore online Master's Degrees from top-ranked universities offered at a fraction of the price of on-campus programs. Flexible to fit your busy life. Learn more. MIT calls its platform OpenCourseWare, and on it, you can find free online courses at the undergraduate and graduate levels (a rarity among other entities on this list) in thousands of topics. One unique element about MIT’s OpenCourseWare is that the bar to placing a course onto the platform is actually somewhat low. It’s completely free to take all of the courses, the textbooks, and generate a transcript. However, when you take a final exam, a 3rd-party online proctoring service, RPNow, needs to monitor you to make sure there’s no cheating. It’s standard practice for all online testing at the college-level.
