I've read both the OCA and OCP Study Guides written by Jeanne Boyarsky and Scott Selikoff in the past. I only did the OCA exam and was looking to upgrade to OCP 11 Programmer II and have done some studying in the new topics. I'm also taking some ethuware tests, but these are sometimes hard. Is it still recommended to take the exam without reading the new book? I'm not so sure if I should wait, because Java has now 6 month release cycles and version 14 is lurking around the corner. What are your thoughts?
