This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Well I don't think you need last minute preparations. You still have one week left. If you give full time to your study, then you can complete the K&B book again and give the master exam again. If you can't devote your full time to preparations, then I would suggest that you go through the two minute drills of the K&B book and solve the self test questions at the end of each chapter and give the all the three master exam once.
