What do you guys/gals think of this?

[gr8ful42day]

I was searching what steps coincide with what pages in the book and stumbled on this.

Have any of you ever used this?

Steps by the Big Book - Steps by the Big Book - Workbook for the 12 Steps of Alcoholics Anonymous (AA) :: Acrobat Version

In this workbook it states (can I rely on this?):
“Doctor’s Opinion” Step 1.
Chapter 1. Bill's Story Step 1
Chapter 2. There Is a Solution Steps 1 and 2
Chapter 3. More About Alcoholism Steps 1 and 2
Chapter 4. We Agnostics Step 2
Chapter 5. How It Works Steps 3 and 4
Chapter 6. Into Action Steps 5 through 11
Chapter 7. Working With Others Step 12

Thanks to sugarbear1 for following post which started me looking to find a guide with Steps/pages in BB:
