Test Strategy – The contractor exam is a four choice multiple-choice test. You will have four choices per question. Some questions may require mathematical computation. All exam questions are written to provide only one BEST answer and are NOT written as trick questions.

All correct answers have the same point value. It is better to try to answer a question with the chance to possibly get it correct (and earn points) than it is to leave that question blank and definitely get it wrong (and lose points).

Ample time is provided to answer all exam questions, so be sure to read all questions and answers completely and carefully before selecting the BEST possible answer to the question.
