If anyone didn't know, I've been taking an online speed reading course. I was a little leary about it at first, because I didn't know how it could be any different than just reading a book about speed reading. I have read the Evelyn Wood book on speed reading and tried it's techniques. This online course definitely was better for me. I won't get into the details of the course too much. But basically it comes down to this. You can't say the words in your head when you are reading. Try saying no in your head while you are reading and keep reading. It's possible, and thus you realize that you can read without subvocalizing. After that, force yourself to read faster and increase your eyespan (the number of words you consciously see at once when looking at them). Tachioscopic (sp) training is used to help increase your eyespan.
In the 6 week class that I just took I improved my reading speed from 300 WPM to between 550 and 650 consistently. I even had one story that everything must have been perfect for or something that I read in 800 WPM (words per minute).
Never give up. Anyone can read faster, and still understand it. This is not skimming. It's not skipping words, it's just reading faster.
