I was 14 when I first learned about PhotoReading, back in 1987. That was years before the how-to book and self-study course was created.
It wasn't until 1992 in the middle of my first year in college that I could take the live seminar.
Within the first week of using PhotoReading, my study time was cut in half, and, when I went to class and we covered what I had PhotoRead and activated back at the dorm, the material came together so much easier.
By the end of that semester, on our toughest final exam on automotive electrical components/systems, I scored the 2nd highest in the class. And, I knew there were other kids in the class that knew the stuff better than I did. But, using PhotoReading, I was able to pull up more correct answers during the test.
So, in my opinion, with PhotoReading you have only to benefit from it.
