Your Study Guide Is Here 

The Private Pilot Condensed Study Guide is the best resource to keep the information locked into your brain. If there's a concept you can't explain, go to the Private Pilot Checkride Textbook (you can purchase that through this link after downloading the study guide) or to an FAA Handbook and study up on that concept. The reason the Checkride Textbook is so valuable is because it only teaches you concepts that will apply to the checkride in the exact same language I use in my videos through social media.
