Hello! This is my first post here. I'd just bought the PR book 2 days ago and have been reading up on it, although haven't finished reading the book yet.

I want to attempt PR for a text book that I am going to teach from. It's about more than 800+ pages divided into 13 chapters.

To be honest, I'd briefly read the whole text book cover to cover a week ago and have quite a good idea what's inside.

To PR on a book of this size:

1.) Should I preview chapter by chapter, each taking no more than 8 minutes? Or should the 8 minute preview be for the whole book of 13 chapters?

2.) Will it be a good idea to PR the whole book in a shot to get the whole picture or is it advisable to do it chapter by chapter?

Thank you.
