Hi Felix.
No that is completely wrong about taking 3 hours to activate a single chapter. Absolutely, completely, totally wrong. And i will tell you another thing that is completely wrong too that has been shared many times on this forum. Do not try to learn photreading on school textbooks or learn photoreading at the same time while learning school subjects. It has been shared many times why it is not a good idea. Do a search on this forum on learning photoreading on textbooks i am sure you will find plenty of information there why it is not a good idea.
3 hours to activate 1 chapter? Wrong. Absolutely no way. Conventionally to learn a textbook with traditional reading it should take you 90 hours. With photoreading it should take you 1/3 of that time 30 hours.
The best advice i can give to you is to photoread only your textbooks and read & study your regular way. School and education is too important to be taking chances on. What i would do if i were you again photoread only and regular read and study your textbooks and there is nothing wrong with photoreading your books multiple times. Then what i would do is find books that have absolutely nothing to do with school say a self help or book of interest say a hobby learn to activate with those books. The books should be basic or simple. What you will find is that you will not have any of this pressure i must make this work so much is riding on me learning to activate this school textbook you will not have that pressure with a book that has nothing to do with school. Remember stress can interfere with the learning process. So if i were you i would activate 15 to 30 of these non-school self help or hobby books and when you get really good at activating those books then transfer that skill to schoolbooks when you really feel confident you know how to activate successfully.
