How the A6 practice test works
This is the ASE A6 Electrical/Electronic Systems test in your browser: 50 questions drawn at random from 492 A6 practice questions, with 90 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 35 right answers out of 50 as a pass: you can miss 15.

The real A6 test

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.
