Ground school is how you learn the theory behind everything you do in the cockpit. Here's an honest comparison of every major option — what they cost, how they teach, and which is right for you.
Ground school covers the aeronautical knowledge required for your FAA Private Pilot Written Test — aerodynamics, weather, airspace, navigation, aircraft systems, regulations, and more. You'll need to pass the written test (70% minimum) before your checkride, and the DPE will test your ground knowledge extensively in the oral exam.
You have several options: structured online courses, self-study from textbooks, or in-person ground school at a flight school. Most students today use online ground school — it's self-paced, thorough, and built around the actual FAA test bank.

Many Part 141 flight schools include ground school as part of their training program. If yours does, you may not need a separate online course. That said, many students find it valuable to supplement their school's ground training with an online course — you can review material at your own pace, rewatch confusing concepts, and do more practice tests than a structured class allows.
If you're doing Part 61 training without a formal ground school component, an online course is essential.
The FAA Private Pilot Airplane (PAR) knowledge test has 60 questions drawn from a published question bank. You need 70% (42/60) to pass. The test covers weather, navigation, regulations, airspace, aerodynamics, and aircraft systems. Most students who complete a quality ground school course pass comfortably — average scores are typically in the 80s.
After completing ground school, use dedicated test prep (Sporty's practice tests, Sheppard Air, or the Gleim question bank) to drill the actual question bank until you're consistently scoring 90%+ before taking the real test.
Our recommendation: Take Pilot Institute for the best learning experience, then use Sporty's practice tests or Sheppard Air to drill the written test questions. This combination consistently produces the highest first-attempt pass rates.
