Hello.
Photoreading is not about developing a photographic memory.
If you are using photoreading for school it will involved many,many multiple superreading & dipping, skittering passes. It will involve adding more & more information to your mind-map.
Keep in mind that you are dealing with a textbook that is completely different from a regular book. Therefore you will be spending much more time than a regular book. A regular book you would activate in say (for a beginning photoreader maybe 90 minutes to 2 hours). A textbook you would activate in 25 to 30 hours.
