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.
The questions are taken from the bigger pool of available questions.
Chances are some of questions you'll face next time will be the same.
On a related note, I recently passed 1Z0-807 and so I still have very fresh memories about related topics.
If you need some assistance or clarification, let me know, I'll be glad to be useful.
