Yesterday I took the exam at Pearson center, with score 80%, not so hign but glad I passed! my average score On enthuware is 80.75%, pretty close to actual score.
To prepare the exam, it took me about 10 months, at least 30 mins per day, and at the weekend I learn more. I don't have much time to study
Java because I'm learning Japanese too:)
learning path: Java OCP 11 Developer Complete Study Guide -> Java OCP 11 Practice Tests -> enthuware practice tests
Some people say that certification is worthless, I don't agree, because of preparing for the exam, I've learnt many useful things, especially the Stream and NIO, and I really used them in my real work.
