How the A1 practice test works
This is the ASE A1 Engine Repair test in your browser: 45 questions drawn at random from 417 A1 practice questions, with 75 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 32 right answers out of 45 as a pass: you can miss 13.

ASE's test specifications split the 45 scored questions into these content areas:
- General Engine Diagnosis18
- Cylinder Head and Valve Train Diagnosis and Repair6

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.
