Hi everyone! Last Friday I passed the 1Z0-817 upgrade exam with 88%. I studied using the following materials (about 2 months of preparation):
OCP Java SE 11 Developer Study Guide by Jeanne Boyarsky and Scott Selikoff (chapters on Java Building Blocks, Lambdas and Functional Interfaces, and Modules)OCP Java SE 8 Programmer II Study Guide by Jeanne Boyarsky and Scott Selikoff (chapters on Functional Programming, Exceptions and Assertions, and NIO.2)Study Guide by Mikalai ZaikinEnthuware Mocks: OCP Java 11 Upgrade - 1Z0-817 Mock Exams Practice Tests/Questions
I passed the 1Z0-810 exam last December, and Functional Programming and NIO.2 questions were pretty straightforward to me.
I took the exam with the OnVue online proctoring and I think that it was a good experience.
In short, I'm very happy with the results!
Cheers,
Pablo.
