Yes, you can certainly do that.
Whatever book you are reading, just write, yes, write
down what you want to know from that book.
Then put 1 question in you other than conscious mind and open the book and just stop somewhere. The answer should be VERY close by. If not, relax & try again.
Asking questions and writing down the answers will greatly help w/ comprehension.
It's like jumping off a cliff, but your other than conscious mind is an ever-present parachute USE IT often & you'll be SO AMAZED
