Test Site Policy
This is a closed-book examination. No reference materials may be used during the examination. All materials brought to the examination site must be left in an unmonitored area at your own risk.

Test Strategy
This is a multiple-choice examination with four choices per question. Some questions require mathematical calculation. Examination questions are written to provide only one BEST answer and are NOT written as trick questions.

All correct answers have equal value. If you are unsure about a particular question, it is better to try to answer the question with the chance of possibly getting it correct (and earning one point) than it is to leave the question blank and definitely get it wrong (and lose one point).

Ample time is provided to answer all examination questions, so be sure to read each question and its four choices completely and carefully before selecting the BEST possible answer to the question.
