For flight instructors

Students pass the written. Then they forget it. Sugar makes it stick.

Memorizing the question bank isn't learning. Sugar saves every question a student misses and brings it back in short practice before the knowledge test, so the idea is still there in the cockpit.

How it works

  1. 1. You create a class and share a join code with your students.
  2. 2. You assign ready-made modules and set the test date.
  3. 3. Every miss comes back on a spaced schedule before the test, and Teach-back asks students to explain it in their own words.
  4. 4. You see who's ready: misses reviewed, what's due, and the topics your class misses most. Never their chats.

Canada and US pilot modules

Canadian Private Pilot (PPAER) modules written from the Canadian Aviation Regulations and the TC AIM, plus US Private Pilot, Instrument and CFI modules from free FAA handbooks. Each question stays marked "Instructor review pending" until an instructor approves it, and you can send corrections from your dashboard.

Practice out loud

A practice examiner asks private pilot questions out loud and reads the choices; you answer by speaking. 10 questions, 7 accepted to pass. Practice only. Not affiliated with the FAA, and not a prediction of your result.
