I really, really dislike Khan Academy. I'm in high school and at least one of my teachers thinks that it's a substitute for actually teaching us. He just puts on a Khan Academy video and we watch it the whole time. Usually we watch a few of them. That, and Sal's voice makes me want to rip my hair out. He repeats things, over and over, like:

"If the box moves five... five meters... five meters per second... five meters per second."

When you have to watch fourty-five minutes of these videos, it starts getting old. Real quick.
