This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
I don't know how questions are distributed, but you need to know all the topics fairly well. If there's an area you find difficult, give it special attention. Don't expect to make up for it on another topic.
