The typing class I took was by far the best, most useful class I had in four years of high school -- and the only one where I could not have learned the material better by simply being left alone in a quiet room with the textbook. (Although being left alone with a computer and a decent learn-to-type program would probably have done just as well; but this was 1994 and my school had typewriters, not computers, so the teacher was actually useful.)
