How the A4 practice test works

This is the ASE A4 Suspension and Steering test in your browser: 40 questions drawn at random from 432 A4 practice questions, with 60 minutes for all of them, the scored length and time of the real test. Each question has four answers and one is right, and you can move between questions and change your answers until time runs out.

When time runs out, the test is submitted as it stands. You see your score and every question you missed, with its explanation. ASE publishes no fixed passing score, so this practice test counts 28 right answers out of 40 as a pass: you can miss 12.

What the A4 test covers

ASE's test specifications split the 40 scored questions into these content areas:

  • Steering Systems Diagnosis and Repair12
  • Suspension Systems Diagnosis and Repair12
  • Wheel Alignment Diagnosis, Adjustment, and Repair11
  • Wheel and Tire Diagnosis and Service5

The real A4 test

The real test has 40 scored questions and 10 research questions that don't count toward your score, mixed in unmarked, all in 60 minutes, so answer every one. You take it at a Prometric test center, or online at home or work if you're eligible, and you can show each question in Spanish beside the English. A4 is one of the eight tests, A1 to A8, that make an ASE-Certified Master Automobile Technician.
