Contractors Exam Information

Exam Strategy


This is a multiple-choice examination with four choices per question. Some questions require mathematical computation. 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 to possibly get it correct (and earn on 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.
