Final answer:
The individual sailor is typically responsible for preparing their own worksheet for the E-4 exam as part of the Navy-wide Advancement Exam process in the United States Navy.
Step-by-step explanation:
For members eligible to take the E-4 exam, the individual responsible for preparing the worksheet is typically the individual sailor themselves. In some cases, guidance and initial preparation may come from within the sailor's chain of command, but it is ultimately the responsibility of each sailor to ensure their worksheet is correctly filled out. This worksheet is part of the Navy-wide Advancement Exam process, which sailors must complete as part of their career progression in the United States Navy.
