Forums IMPORTANT: PLEASE READ PhotoReading, Memory Optimizer Purpose during Photoreading

I think I'm having trouble with my Photoreading purpose.

How do you all affirm your purpose at the start?
- Say it to yourself once, and forget it when you Photoread?
- Chant it a few times, and forget it when you Photoread?
- Constantly think of that purpose even when Photoreading?
- Write it down at the start and read it before and after Photoreading?

Creating a purpose is a foreign concept to me right now. I am also worried that my purpose will vanish halfway when I'm focused on thinking "One, Two, One, Two" during the Photoread step.

Secondly, how would you structure a purpose when you're Photoreading a 500-page textbook with roughly 20 chapters for an exam?
- "The purpose of this Photoreading session is to remember the entire Biology syllabus."
- "The purpose of this Photoreading session is to learn everything necessary to score high marks for my Biology exam"?

Thanks!
