Only had time to deal with one chapter?
Don't let time get away. Set a timer, keep to your purpose.
How long did you preview?
How long did you postview, how many questions did you write down and how many trigger words did you write down.
Where did you start looking when you asked where could I find the answer? Did you use the index, table of content? or just open the book?
How long was your activation pass?
For starters i didn't pick a lot of information, so I was a little confused.
Welcome to the beginners experience. Confusion is good it means the mind is working on accessing the neural networks.
Yep skittering usually is the best option for textbooks.
Textbooks often take 25 to 100 hours to complete with traditional reading. Depending on how complex and new the information is for you it's possible that 1 hour is excellent time. You might have been reading it 2 or 3 times with traditional reading to get the same confident knowledge of where everything is located.
Use the system first on a couple of 200 page non-fiction books that you are interested in. Move away from textbooks until you understand the system confidently to determine what you need to adjust when it is taking too long in a textbook. You get that experience faster with non-fiction books than textbooks.
