The FAA written test can be done at anytime before or during your training. It needs to be done by the time you take your checkride. The written test is comprised of 60 questions with a passing grade of 70%. Those 60 questions are pulled from a bank of just over 800 questions, we have the test prep online available  here. Your checkride will be with a Designated Pilot Examiner (DPE) and will consist of two parts. The first half will be an oral examination, where you will answer questions about flying. The second half is the practical examination, where you will fly maneuvers in the airplane with the DPE. After you pass both parts, you will receive your Private Pilot License!
