I came across this site while searching for educational instructional tutorial videos for my son who is struggling with calculus. While I did not find the video on the topic I was looking for because it appears this site is new and is still gathering content. I love the idea, quality educational tutorial videos for a low price. Any person can contribute and I imagine there are many substitute teachers and underemployed Phd’s that could really take advantage of this site and make some good money while passing on their knowledge to others that need it.
