There is a difference between reading and studying. If a person can read a book and then get 80% comprehension on a test, then 80% comprehension is very realistic for someone who uses the full PhotoReading system. If that person needs to study to get 80% comprehension, then PhotoReading and studying is in order.
We've talked about Pete's demonstrations in other posts.
Can you give an example of the types of books you are working with right now, and also explain how you are doing all 5 steps of PhotoReading?
You can count on cutting your study time down to a third or less and achieve better comprehension and retention as a beginner.
