Excellent test prep book but needs some updating for the L1 test.

This book was a vey helpful refresher for A1-A8 ASE tests. If you have a good understanding of automotive systems from work experience, and you are decent with interpreting wiring diagrams, you shouldn't have a problem getting your certifications with this book. There are good hints/refreshers with each group of questions too
I took each practice test and wrote my answers down, went through the answers in the back, and read the reasons for all the failed ones. A few of the questions are almost word for word ASE test questions especially in the auto trans section.
The L1 prep section is very good information and I don't think I would have passed that test without it. But the actual L1 test had a few more questions about A/F ratio sensors that I feel this book didn't get into (maybe the info was more relevant at the time of publishing). Also there were two typos in the answer section for L1 where the wrong answer letter is printed.
I do think this book is a very useful study guide and would definitely recommend it. No study guide is going to be perfect. I passed my A1-A8 easily with perfect scores on 2 of them. My L1 test score was 41/50 and it takes 34/50 to pass. I would recommend this book to anyone studying for these ASE tests. Good luck!
