In the 30 minute challenge superreading and dipping is part of the challenge. We start to manually activate.
I had a group of my students meet on Sunday. Fun day. I set them some PhotoReading challenges. They had to mind map a in the four hours we PhotoRead 15, book mind mapped and discussed 3 books which they only had 15 minutes with (greatly reducing the 30 minute challenge). In the 15 minutes they had to superread and dip for information that satisfied their goals. I threw a couple of additional challenges at them.
