So today I took 1Z0-819 and passed with 76%. Just few things I want to say:
* very little time for me - I was not able to complete 3-4 questions in time so I just guessed , Oracle don't be crazy, please add at least 15 minutes to test * it was tough because some questions were complex and are time consuming and I needed help of paper
* I feel I could make better if I had more time
* I did passed 1Z0-815 with 85% a year ago - thank you Oracle to make it pointless for me
* I paid full exam fee, just not knowing about the special offer from Oracle, again perfect timing from my side
* I learned only from Scott and Jeanne books + completed all tests from new practice book, thank you for this very good study material!
* I am not very Java experienced developer, just <3years, however I work professionally as Java developer
I started learning in mid November 2020, going through Java OCP 11 Programmer I and II study guides very carefully and slowly. I devoted like 1-2 hours daily on average (some days more hours like 3-5, some days skipped completely) but I was trying to study something every day. After each chapter I did online test from the book to make sure I understand. I also during reading the books wrote short notes about things I learned on paper, just much simpler like in book, especially the things I knew I will forget. In mid February I was ready with the books. Then I went through my notes again to recap things again, it took my 1-2 weeks. Then I started doing online test questions from Java OCP 11 Practice tests. For wrong questions I again looked at the study guide. It took me cca 2-3 weeks to do all online tests. Just a week before the exam day I did 6 simulations of exams (50 questions, 90mins) from the study books and practice book. I would say it helped me to better suit the test situation and feel the time in background so on real test I knew if I am slow or quick enough. So to recap it took me cca 4 months to prepare and it was not easy since I have 2 little children and full-time work so I am happy I managed it. I think the key to pass is the speed, it will help you a lot if you can understand the question and read the code fast and to be able to do so you need to practice a lot. Also another good tip is on real exam skip long questions and work on them at the end, you can mark them for review, you process with simpler questions which you are sure you know. It is good feeling when you know you have a lot of questions already answered and you feel better then when you start working on hard ones.
It also depends what's your current java baseline. Of course you can make it in one month if you are currently strong in java SE api and object-oriented design ;)
I am also learning for this certification and I am really nervous because I have no professional experience with Java.
Can you, please tell us how much did the Java working experience helped you in passing this exam?
And also, what were the main chapters your certification questions were about? (I am very "scared" of the module and security ones ).
