Ready for a challenge? This Marathon is a massive practice test that contains all 72 questions from our Class D Commercial Licence database for Ontario. If you select an incorrect answer, we’ll remember that question and will display it to you again at the end of the Marathon - until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the province’s regular practice tests, but before the Exam Simulator. It might take some time, but you can do this!
Ensuring the accuracy and quality of our practice tests is paramount. Learn more about our rigorous standards in our Commitment to Accuracy article.

If you successfully complete all the practice tests for your province/territory, we promise you a passing grade on your official written knowledge test or we'll refund your money. Your most recent completion of all the tests should be not earlier than 30 days before your exam date.
