Hi! I took 1Z0-819 and I passed with score 78%.
Just a few thing I want to say:
* it is the first certification of my life, which I got when I was 16 years old.
* I studied hard using OCP study guide programmer I and II.
* I used enthuware mock exams and I did all practice tests in OCP book.
* I used oracle docs.
* I wrote everything that I learned with enthuware, OCP books and oracle docs to improve understanding.
