Pay attention, because there will be a test afterwards. Just kidding. The Jeppesen JS312400 Private Pilot FAA Airman Knowledge test guide has an awful lot of great information packed into a paperback book. It includes not just test questions and answers, but also detailed information about each topic and useful study references. The subject areas are neatly organized by topic and they're coordinated with the Private Pilot Manual for easy cross-checking back and forth.
This test guide has 3-hole punched, perforated pages, so that you can easily select and remove specific pages or sections for more effective studying. There's also a sliding mask for convenient self-testing, plus full-color charts that are identical to those you'll find on the actual FAA test.
