So let us say I want to PR 3 different books, how shall i go about it.... prepare & preview for all three books, and then PR the 3 books together or do the steps on by one for each book.

I would like to apply this system even while PRing chapters from a book not whole books, say today I want to study three subjects. What do I do? do the previewing together, PR together and then activate from the 3 books accordingly?

What is the fastest and of course the most effective way after all?

regards

Adrian
