FAQs

01Do the CDL practice questions appear on the official test?

The questions may not be an exact replica of the exam questions, but they closely follow the content covered in the real exam. By practicing with our questions, learners can develop a strong understanding of the concepts and topics that are essential for success in the real exam.

02How does my account sync between the app and the web?

Please log in to the app/web by our login feature with the same email that was registered with the PRO version so that all the data and progress can be synchronized.

03Can I use the CDL Prep results for the real test?

No. While our CDL Prep test is designed to mirror the actual CDL in content and format closely, it is intended solely as a practice tool to help learners prepare and familiarize themselves with the test. The results from our practice tests, while useful for gauging one's progress, do not carry the same weight or recognition as the official test.

04Can I change to another language?

No. At the moment, our platform only has an English language version available. Our development team is actively reviewing the feasibility and timeline for adding new language options in the future.
