I have passed my OCPJP today with 91% on my second visit of testing ceter (my yesterday's attempt was canceled due to technical problem while sitting there for 1,5 hour without starting the exam...). The exam was quite easy compered to mocks in K&B book and CertPal. Actually two hours were more than enough for me.
There was one really mean question about what change can be introduced in one class without affecting the other class with one possible answer. In my opinion there were two possible answers one not affecting result of the other class and the other was changing the result, but both didn't affect the other class (compilation, Exception).
