Clip the pages with the answers together and photoread. It might mean you miss some questions while photoreading because they are part of the pages clipped together but that way you can test yourself without feeling that you have skewed the test.

It's helpful if the answers are at the end of the book. You just rubber band that part shut for the photoreading and test taking portion (you have to remove the rubber band to cheat or look up the answer too soon )
