Why $49 alone when the 9-book kit is $5? Each book is listed individually at $49 so the shelf has a transparent per-book price ($441 for all 9). Unless you want only this single PDF, the MBB Starter Kit ($5) includes this exact book plus all 8 others and 3 timed tests.

01The problem
Firms tell you the name of the stage — a coffee chat, a one-page CV, an online assessment, a case or a PEI story — without showing you what a working example looks like from the inside.
02The fix
Know what every chatbot turn wants, spot the math traps before they cost you, and use the five-minute video window for a clear one-minute recommendation, with three days of practice to get there
