Ready for a challenge? This Marathon is a massive practice test that contains all 384 questions from our Class F 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!
