Most of the stuff I put up on this blog is actually stuff I use or will use so I put it here so it can be here even after my computer dies and also so I can get to it from where ever I am.
With a library of over 2,400 videos covering everything from arithmetic to physics, finance, and history and 125 practice exercises, we're on a mission to help you learn whatever you want, whenever you want, at your own pace.
