Here's the whole story! We published the SCJP 5 Study Guide in December - so most people in most locations are able to get that book now. We are discussing the possibility of a second book, a so-called "practice exam" book. Some how Amazon is listing that book as being available in May, which is unlikely since we haven't even officially decided to do it yet
But, the SCJP 5 Study Guide DOES have about 280 mock questions (some via a CD or a website), so we think it's pretty good from a practice question perspective.
Spot false dilemmas now, ask me how!
