This website is horrible. No detail explanation, so abstract. When you watch the video, you will be discouraged a lot...that is not only you. Even I go to Harvard, I really don't understand and have a difficult time to understand the lectures. Even 1 star is a greatest compliment. I want to give -100 (minus 100).
Bottom Line: No, I would not recommend this to a friend
