The Motor Age Training S3 Drivetrain Practice Test includes 55 practice questions written by our technical editors familiar with the content for this book and the test taking process.The actual ASE certification tests generally include between 40 and 75 scored, multiple-choice questions measuring your knowledge in various content areas. We have added more questions to our practice tests in order to better prepare you for test taking process. The actual ASE test could contain additional questions that are included for statistical research purposes only. Your answers to those questions will not affect your test score, but since you do not know which ones they are, you should answer all questions in the test. The 5-Year Recertification Test will have fewer questions, but will cover the same content areas as those in the official task list.
