If you have fully activated the book, then you will feel confident about the material when you sit for the test.
If you just PhotoRead and rely on spontaneous activation you, as a beginning PhotoReader, may not feel as confident. The information will be coming up from the channels of your right brain. It could feel like a burst of creativity, or intuition, or a hunch, or as if you are making it up. And in that, as you might imagine, is a potential problem.
So, play with it. See how it works for you. See how you respond. It's fun stuff.
