Familiarize Yourself with the Format—the Private Pilot written test FAA test contains 60 multiple-choice questions, and you have two hours to complete it. Any of the written tests may also include validation questions, which are questions used to accumulate data for statistical analysis of test question validity and performance. Validation questions are non-scored questions, and do NOT count for or against your final test score. The posted number of questions does NOT include validation questions.
A description of each test, allotted times, and total questions are available via the Airman Knowldge Testing Matrix.
