Tips For Passing the Commercial Driver's License (CDL) Permit Test
- Practice Makes Perfect: The best way to both mentally and physically prepare for the written exam is to take practice tests. Start out with open-book tests and gradually work your way up to giving yourself a time limit. Finally, before the big day, take a practice exam as if it were the real thing without any help. This will give you a good indication of how well you understand the material.
- Understand Instead of Memorize: Memorizing information can be helpful for the written exam, but the key to being fully prepared is to understand the material rather than just memorizing it. Understanding the material will allow you to answer questions correctly no matter how they are worded.
- Real World Applications: When struggling to understand concepts, create real-world scenarios to make the information more relevant to your life. Doing this will make it easier to remember come test time.
- Utilize Study Strategies: Utilizing study strategies such as flashcards, songs, rhymes, and phrases can help you remember the material.
- Be Fresh and Alert: The night before the exam, get a good night's sleep and eat a filling breakfast on the morning of the exam. This will ensure you are fresh and alert to take your exam.
- Begin Early and Space out Your Studying: It is important to give yourself ample time before the exam to get familiar with the material and get your mind ready for the big day. Consider taking a training course online or in-person, if it's required. Shop around for a course that works best for you. By following these tips, you will be well prepared for your written CDL exam and on your way to a successful career.
