CDL Exam Prep 2020-2021: A CDL Study Guide with 425 Test Questions and Answer Explanations for the Commercial Driver’s License Exam (Training Book for All Classes)

Do NOT purchase this book, it is full of errors! While the written information may be accurate, the answers on the practice test are frequently misidentified. This means you can not just check your selection (A, B, C or D) against their answer key and assume you picked the right answer. You’ll have to go back and actually read the options. In short, it’s a giant pain. Save yourself a lot of headache, get a different study guide!!!!

Some of the answers on the general knowledge test don’t match up at the questions. For example: the correct answer would be on A, but they put the correct answer was C. And at least 1 question doesn’t have the correct answer for any of the choices. Although the overall information in the book is good.

I have found so many errors in this book it's not even funny. A lot of the questions in the test section don't match up with the answers in the answer section. The answers are written differently than how the question answers read. I am left to verify answers in the reading/description area. Or search online for the correct answer. Many gramatical and spelling errors! It's very confusing in an already confusing subject.

I found the material helpful, though I found the writer misspelled a word in here. I did not let that deter me, but found it most helpful to study all the tests including the school bus exams.

My book came upside down and backwards. Kind of wondering how you could mess up that bad.

The book was good. Easy, quick to study. I went for my exam today. And all the questions I was prepping for, but they said these question are up to date with the actual CDL questions NYC. BUT EVEN CLOSE . I didn’t run into not one question from this book on the ACTUAL EXAM. Butttttttttt I passed. BARELY!.. i should’ve just ready the DMV book

Got for my fiancee. He said it really is helping him to learn for the test. The practice tests are a great tool!

As always, very organized and easy to follow. An excellent guide for this exam. I feel prepared!
