The ASE G1 study guide is intended to help technicians prepare for the G1 Auto Maintenance & Light Repair Test. The G1 test prep manual contains Test Specifications, a task list, and sample questions with answers. After studying this guide, you should you should be well prepared to take the test.  Certification in Auto Maintenance & Light Repair is somewhat different from other ASE certifications.  Technicians who pass the G1 exam, and have at least one year of hands-on on-the-job experience in auto maintenance and light repair (half may be substituted by vocational training in the maintenance 7 light repair area), you will be certified in this G1 area. 

The ASE G1 test contains 55 scored questions, and 10 unscored questions, and you will have 1 1/2 hours (90 minutes) to complete the test. The questions, written by service industry professionals skilled with all aspects of maintenance and light repair, are completely job-related. These exam tests skills you need to know in order to do the job correctly.  Theoretical knowledge or capability is not covered.  The Test Specifications and the Task List, provide you with a map of the topics that will be covered on the test. The sample questions and answers will expose you to the types of multiple-choice questions typically seen on ASE tests. 

It is best for you to be well-rested for the test so you will be alert and prepared. It is always better to arrive early to the test location, and late arrivals may be turned away.  Also, bring your test center admission ticket and a current photo ID such as your driver’s license. Storage lockers will be available for your personal items, and cell phones. Your test appointment will begin with a short video to familiarize you with our computer-based testing system.  The G1 test has a time limit of 1 1/2 hours total. The timer on the computer screen will show the amount of time left. If a question is to difficult, select your best guess and flag the question. If you have time after you complete all the test questions, revisit your flagged questions for a final review of the question & answers. Applicants are scored on correct answers only, so you should try to answer every question as well as you can.
