I don't normally answer questions like this. But I believe that the OCP tests contain nothing more than is taught about these things in the corresponding courses (that is, not much). Indeed, I believe that the tests are based entirely on the courses, and so being familiar with the course materials is probably the best preparation. You can download the course materials from Howard Rogers' web page Courses.

I am taking my OCP exams from past 2 months and 3 exams are yet to go. I am going through Couchman's OCP book and also using the online experience with Oracle in my job. Still there are certain areas which I need to get information about like Oracle Expert and OEM. There would be questions on these in Performance Tuning exams. But, I have not started using these and also Couchman's book do not talk about this so I need to get the material for preparing for these. Is there any good test material or downloadable contents for these. If you know please help me by sending the information I need. Thanks in advance again.
