✔ FREE SD CDL Air Brake Marathon 2017

South Dakota DMV Permit Test Fact Sheet:

How many questions:25
How many correct answers to pass:20
Passing score:80%
Got a couple of hours to spare? This South Dakota CDL Air Brake Marathon is a new practice test that contains a combination of all 114 questions that we have available for this SD endorsement. If you select a wrong answer, we’ll remember that question and will display it to you again at the very 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. As you work your way through the Marathon, you’ll see that unlike the other South Dakota CDL practice tests there are no explanations and no hints here. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. It might take some time, but you can do this!
