If you’re reading this, you’re probably at that point in your career where you’ve decided to take the next big step. Getting ASE certified isn’t just about adding credentials to your toolbox—it’s about proving to yourself, your employer, and your customers that you know your stuff. The A1 Engine Repair test is the foundation, and passing it shows you understand what makes an engine tick, from the valve train down to the short block.
This book was written by technicians, for technicians. We know you’re busy. You’re not looking for a textbook that rehashes everything you learned in school. You need something practical, something that gets to the point and helps you prepare without wasting your time. That’s exactly what this is.
Inside, you’ll find practice questions that cover the topics of the actual ASE exam. Every question is followed by a detailed explanation. We’ve designed these questions to make you think, to challenge your assumptions, and to fill in the gaps you might not even know you had.
This book is unofficial, which means it’s not affiliated with ASE, but it’s accurate, it’s relevant, and it’s built on years of experience in the trenches. We’ve been where you are, and we’ve helped plenty of other techs get through this process. So grab a highlighter, find a quiet corner, and get to work. The more questions you work through now, the fewer surprises you’ll have on test day.
Let’s get you certified.
