This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Mocks do not necessarily reflect what's in the exam, and what's not. If I were you, I'd concentrate on reading the book (HFSJ), written by authors involved in the exam, who know what is there, and what's not. The tutorial on dynamic attributes was added here, but apart from that, you'll be fine.
