The CDL Study Guide 2020 and 2021: CDL Training Book 2020 and 2021 aims to help individuals prepare for the Commercial Drivers License Exam. However, customer feedback suggests that the book falls short in some key areas. Several customers expressed disappointment with the book, stating that it left out important information for testing and caused them to fail the exam. They recommend getting a free CDL book from the local DMV instead. Other customers found the book to be lacking in depth for their specific state CDL Class A permit test. They struggled with the practice questions provided and found more success with CDL practice question apps that offered detailed explanations for incorrect answers. Some customers felt that purchasing the book was a waste of money, as it did not include a pre-trip test and the same information could be obtained for free at the DMV. One recurring issue mentioned by customers is the presence of grammatical errors and sentence structure issues throughout the book. This can be distracting and may impact the overall quality of the material. In a more positive review, one customer mentioned that the book is an improvement over the state-issued manual and is easier to read. However, they noted that spelling and grammar issues persist, and a specific example of contradictory information was identified. Overall, the CDL Study Guide 2020 and 2021: CDL Training Book 2020 and 2021 receives mixed feedback. While some customers found it helpful and easier to read than the state-issued manual, others feel that it is lacking in important content and contains grammatical errors.
