This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Here is an anonymous unofficial answer I have received at JavaOne, by someone really really close to the certification and knows about grading.
