Yea this article sounds like a good strategy on how to get correct answers on a test of things you don't understand.

I just think the categorization of "textbook" is nonsense to start with. Of course you want a book with text as opposed to a picture book.

You have to start with the right book. The variability between books on a subject is so huge and probably even different person to person based on prior knowledge.
