v2.0 This test consists of fifty multiple-choice questions. All questions are from the IPC Component Identification training video (DVD-64C). Each question has only one most correct answer. Circle the letter corresponding to your selection for each test item. If you want to change an answer, erase your choice completely. You should read through the questions and answer those you are sure of first. After your first pass through the test, then go back and answer the questions that you were not sure of. If two answers appear to be correct, pick the answer that seems to be the most correct response. When you are finished, check to make sure you have answered all of the questions. Turn in the test materials to the instructor. The passing grade for this test is 70% (35 or more correct answers). Good luck! 1
