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.
Man, one good thing is to keep the entire architecture of your application in your head. You'll be asked things, like, what did you use, RMI or Sockets, how does the user searches for records in your GUI, and so on... for instance, in my case, in one of the answers, I said "I extended the javax.swing.table.AbstractTableModel class and added 5 extra methods in my table model...", I think it is important to give implementation details in your answers, because the idea of this exam is to prove that you were the person that really coded, wrote and planned everything that was delivered.
And for your second question, it's kindda' hard to say, but I believe that they do read everything (at least, that's what I hope )
