The OCP exams are designed to be very complete and to adequately test your familiarity with Oracle products and the procedures associated with them. While there is no substitute for knowledge, you can improve your score significantly by taking as many of the sample exams as possible.
They provide a good idea of the material the exams cover and the style in which it's presented.
The OCP exams have no trick questions. However, they assume familiarity with the Oracle documentation, and some test questions address documentation samples. The nature of Oracle database administration cannot demand that you memorize all of the tens of thousands of facts; rather, the test assumes that you know where to go to look up the information. Unless you are familiar with the Oracle documentation, you may not have enough time to research some of the questions.
Many candidates are afraid of the rigorous reputation of the OCP exam and often put off taking the test even after they have registered for it. However, there are a wealth of books and online tools to assist students in test preparation, and those candidates who have been diligent in their studies often pass the test with relative ease. Among the most valuable resources are the following:

1. Oracle8 Networking by Hugo Toledo (Oracle Press, 1999). This is the optional text for this course and contains a wealth of helpful information related to the exams, the material they cover, and the best ways to prepare for them.

During the exam, candidates may bypass any questions they are not sure about and return to them later in the test.
The best strategy is to make one pass through all the questions, marking the answers about which you are most confident. The exam also allows questions to be answered and flagged, so that you can return to them later on. This enables you to make the best use of your time and ensures that you will get through the entire exam at least once in the allotted time. If you plan carefully, you will have time at the end to go back to those questions you were not sure about. The best policy is to answer every question, if possible. If you can eliminate even one answer, you should venture a guess.
The OCP exam informs you immediately of your pass/fail status and also provides a listing of all missed as well as correctly answered questions. You will receive a hard-copy version at the end of the exam.
