## How it works

- Pick an answer, then tell the coach why. Type it or say it.
- The coach checks your reasoning, not just the letter you picked, and explains the reasoning behind each miss.
- Each answer is graded satisfactory, marginal, or unsatisfactory against its ACS code. A right answer you can't explain is marginal.
- No timer, and no account needed to start.

## Keep your progress

The demo is a short free sample: a few questions, ending early at your first explained miss. Sign in to keep your answers and carry the ACS codes you missed into your next mock oral. Practice past the free sample is written prep for Private Pilot Airplane (PAR) or Instrument Rating Airplane (IRA), one purchase per rating.
