Want to try a neat experiment.
Pick your toughest class.
Go to the library and PhotoRead six books on the topic--don't worry about activation. Do this for a couple of days in a row, longer if you can. Don't worry about form; just do it.
Notice what happens in your classes, in your readings, and in your studies. Many, many people have told me that suddenly the class became easier. The information was not as difficult to understand. The lectures became activation sessions for the books.
Pay attention to your dreams, your thoughts, and your conversations. See how the stuff from that subject seeps into your life!
Have fun...
