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.
I have done lots of mock exams and sample questions now, and for the questions where you have to select multiple answers, some of them tell you how many to select ("choose the two correct answers") and some of them don't ("choose all the correct answers"). Which format is used in the actual SCJP 1.4 exam? Obviously the first format improves your chance of getting the question right!
