- 40correct answers to pass
- 80%passing score
Ready to put your new knowledge to the test? This Iowa CDL General Knowledge Marathon is a super-challenging study tool that contains all 693 questions from our database for this IA endorsement. If you select a wrong answer, we’ll remember that question and will display it to you again at the end of the exam 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 state’s “regular” tests, but before the “Exam”. Good luck!
