The journey to obtaining a PPL license involves a combination of theoretical knowledge and practical flying skills. While it's possible to encounter setbacks these do not necessarily disqualify you from achieving your goal.
If you fail a component such as the written exam or a checkride it doesn't mean the end of your journey. You can retake the test after additional preparation and training. For instance if you fail the knowledge test you may need to receive additional instruction and obtain an endorsement from an authorized instructor certifying that you are proficient to retake the test.

encountering a failure during your training does not mean you cannot meet the requirements to get a private pilot license. With determination additional training and a positive mindset you can overcome challenges and successfully obtain your PPL.
