You always need a purpose and you always superread and dip with one of your mind probing questions in mind. You are looking for answers to your questions.
I suggest you focus on your preparation for the exam and learn the PhotoReading system as a whole after the exam. You may play with the PhotoReading step and PhotoRead your textbooks however use your traditional method for studying and reading to activate it. You won't have the speed yet and still it may improve your grade.
