I must say, that during my preparation phase I made section tests after each chapter of 'Mala Gupta' book.
Then I run whizlab tests.
Diagnostic - 74%
Practice I - 83%
Practice II - 86%
Practice III - 80%
Practice IV - 80%
Practice V - 79%
Final - 86%
However, on Whizlab tests, I had many problems with questions about strange methods, which DID NOT appear on the exam. Like String 'copyValueOf(char[] data, int offset, int count)'. Most questions were less tricky than enthuware and I have got the feeling, that Enthuware helped me much more.
My enthuware results of tests were: (As I said, I made section tests before, so I can be taken as a bit cheating...)
Foundation - 78%
Test 1 - 90%
Test 2 - 81%
Test 3 - 81%
Test 4 - 84%
Test 5 - 87%
Test 6 - 90%
Test 7 - 100% :O
Final test - 86%
After each test, I was carefully reading explenations and took notes, additionaly I tried to code a bit (At the beginning in IDE, later I switched to notepad++

Many people said that reall exam is easier, but I did not get that feeling. Maybe questions were a bit less tricky, but stress is making the big difference. During my mock exams I was ready somehow between 15-25 minutes before end, and during real exam I was choosing last answer 3 seconds before the end!
In the end I passed!
Now next step before me!
Do you know if the knowledge gap between OCA and OCP is very big?
