What problems is edX solving and how is that benefiting you?
Whenever I feel like I want to know more about a certain topic, I check the edX courses available and have a look. Since most of the courses are free I can simply give it a go. Even if sometimes it seems like the course is very long, if you're determined you can watch several videos a day and complete the course faster.
I can easily extent my knowledge of different areas in my own pace, which is particularly important when having a full time job. Also, I can rewatch single classes again whenever needed. Review collected by and hosted on G2.com.
