<\/span>2. Mechanical Concepts (44 questions)<\/h3>\n

This section consists of questions regarding the use of mechanical devices related to power plant operations. You will see line drawings of pulleys, levers, gears, ramps, and fulcrums, and be expected to demonstrate your understanding of motion, momentum, pressure, and related physics concepts within the 20-minute time limit.<\/p>\n

<\/span>3. Mathematical Usage (18-46 questions)<\/h3>\n

This section consists of questions covering mathematical formulas and mathematical problem-solving skills. Typically, if you are applying for a plant operator position, you will take the short-form version of this test battery, which contains 18 questions and has a 7-minute time limit.

<\/span>How the Test is Scored<\/h2>\n

Your score is determined by the number of questions you answer correctly. This means there is no penalty for answering a question incorrectly, so you should at least pencil in a guess if you aren’t sure of the correct answer.<\/p>\n

Your scores for each section of the test are combined into an index score on a range of 0-15. The score needed to pass the exam will be different depending on the job you wish to pursue and at which company you wish to work.<\/p>\n
