  • can u make a separate channel for math and science? because its a pain to have to scroll through 7 pages off geometry and trig and algebra and pre-alg or whatever to find the video on the lesson were doing in science...sorry

  • @twix5690 I'm indexing these videos at the Lucid Education website. Go there and click on Video Index and you will find them better organized. YouTube only provides, at least for now, minimal ability to organize a large number of videos within a channel.

  • Love your videos! 5 stars.

    What is the name of the program you use, which lets you draw and it shows up on the screen?

  • I'm using Camtasia Studio, which is pretty expensive, but there is free software out there that will also do the same thing. It's simply doing a screen capture.

  • You should team up with Khan, you two can save the world together. He is doing awesome things and so are you. You guys can start Mcat reviews and all kinds of stuff. That'd be awesome :D

  • Very clear , easy to understand

  • I am familiar with screen captures, but how do you draw with it? It looks like you are drawing with a pen. Are you using your mouse?
