Take a printout of each exam topics (with sub-objectives) in the separate sheet. These papers will be your preparation monitor across your self-study travel. Just add three different checkboxes on each objective and track it like below:
|Theory Knowledge||Practical Knowledge||Exam Knowledge|
|Define the scope of variables|
|Define the structure of a Java class|
|Create executable Java applications with a main method; Run a Java program from the command line; produce_console_output|
|Import other Java packages to make them accessible in your code|
|Compare and contrast the features and components of Java such as: platform independence, object orientation, encapsulation, etc|

Get some working knowledge of each exam objectives. Write programs and run it on your system. Do not skip any exam syllabus. Play more with your programs by adding/changing alternate code/methods. Note that most of the Java Certification questions are program based, so it is mandatory advice to a program to get the good practical knowledge to clear Oracle exam. The program directory created in your system must have chapter-wise folders for ease of review. Repeat this till you get good knowledge in exam chapters.

The key to achieve a good score in real exam is solving as many mock exams as possible.
