Passed with a 75% thanks to lots of studying and practice exams. I have a ton of pre-Java8 experience but the
Java 8 stuff adds a lot to think about.
I used the following book:
OCP: Oracle Certified Professional Java SE 8 Programmer II Study Guide: Exam 1Z0-809
by Jeanne Boyarsky et al.
I did all the end-of-chapter exams at least once. I did the online Sybex exams that come with the book and earned 53%, 50%, and 53% on the days immediately preceeding the actual
test.
In July I earned an 87% on the OCAJ8P Exam 1Z0-808 in July using the book:
OCA: Oracle Certified Associate Java SE 8 Programmer I Study Guide: Exam 1Z0-808
by Jeanne Boyarsky et al.
Thanks to Jeanne Boyarsky and Scott Selikoff for the great study guides.
