The DPS Written Knowledge Test will be provided to you at the end of the six-hour course (8 levels). This means that you wonβt need to take the Written Knowledge Test at the DPS! The test will consist of 30 multiple-choice questions. You have one hour to complete the test and must score at least 70% or better (at least 21 out of 30 questions correct) in order to pass and receive a Certificate of Completion from Aceable. If you fail the Written Knowledge test, you can take it again 24 hours later. You'll have three attempts to pass, per state regulations. After your third failure, you'll need to restart the course free of charge before you can attempt the exam again.
