The ground school that grades your oral exam answers.
12 modules covering every FAA written exam topic — plus the only online ground school with instant, instructor-quality oral exam grading. Type your answer to any DPE question and get immediate feedback just like sitting with your CFI. Built by a real flight instructor flying from Truckee-Tahoe.
Built differently from
every other ground school
The big corporate ground schools charge $300–$400 for video lectures and a quiz bank. We built something genuinely better — for a fraction of the price.
The only ground school that grades your oral exam answers
Sporty's, King Schools, Gleim — none of them grade your oral exam answers. You type what you'd say to a DPE, and you get immediate instructor-quality feedback: what you got right, what's missing, and a complete model answer. This feature alone is worth more than the entire course price.
Written exam simulator that explains every answer
300+ questions across all 10 ACS subject areas — FAA-style format, timed 60-question tests, randomized every time. But unlike other simulators, every question includes a detailed explanation of why the right answer is right and why the wrong answers are wrong. You learn, not just drill.
Written by your actual CFI — not a content factory
This course was built by Preston, the instructor you're flying with — not outsourced to a content agency. The mountain flying module covers the Sierra Nevada specifically. The W&B problems use a real Cessna 172. The KTRK density altitude callouts are real conditions you'll actually face.
$97 one-time vs. $300–$400 subscription elsewhere
Sporty's: $319. King Schools: $299. Gleim: $159 per year. Blue Jewel: $97 once — lifetime access, all 12 modules, instant oral exam grading, exam simulator, W&B and navlog practice, and optional live video sessions with your instructor for $197 total.

The oral exam
grader no one else has
Every other ground school preps you for the written test. None of them prepare you for the oral — the part that fails more students. Our grader acts like a DPE-trained instructor, evaluating every answer you type the same way your CFI or examiner would — immediately, with no waiting.
A practice exam that actually teaches
Most question banks just tell you right or wrong. Ours gives you a full explanation of every answer — why the correct choice is correct and why each wrong choice is wrong. You walk out of a practice test knowing more than when you started.
Proportionally weighted to match the actual FAA ACS — same distribution of topic areas as the real test.
2.5 hour countdown, randomized questions, dot navigation to jump to any question — identical to the Pearson VUE testing experience.
After each test, a color-coded bar chart shows exactly which subject areas need work — so you study smart, not just more.
Learning mode shows explanations after each answer. Exam mode saves all feedback for review at the end — simulating real test conditions.

Built for pilots who
want to actually understand it
"I passed my checkride on the first try and I honestly credit this course. The oral exam prep section is what made the difference — I practiced the density altitude question so many times that when my DPE asked it I answered without hesitating. Preston knows exactly what examiners are looking for because he's right here at KTRK with us."
"The weather modules are seriously the best I've found. I'd tried two other ground schools and neither of them explained mountain wave or lenticular clouds the way this course does. Flying out of Truckee means you actually need to understand Sierra Nevada weather — and this course teaches it like that matters, because it does."
"Scored 91% on my written exam. The practice simulator is what got me there — the topic breakdown after each test showed I was weak on regulations so I hammered that section. Every wrong answer has a real explanation, not just 'incorrect.' No other practice test I tried does this. Worth every dollar."
