Exam prep for coaches, with 900+ practice questions
Coaches prepare for a certification exam with timed practice tests, instant feedback and written answers scored by AI.

The problem
Coaches Development teaches fitness coaches. Its students needed one place to study and practise for a hard exam, on a phone or a laptop.
Multiple choice alone cannot test judgment. A good coach must also explain what to do, and why.
What we built
- Practice questionsThe site lists 900+ questions. They are original, not taken from any official exam.
- Timed testsPractice under real exam conditions, in an exam-like format.
- Instant feedbackDetailed feedback after each answer, so coaches learn as they go.
- Written answersAI scores written assignments against a rubric. A score of 70 passes.
- Sign-in for everyoneCoaches sign in with Google or with email.

How it works
- A coach signs in with Google or email.
- They take timed practice tests in the exam's format.
- Each answer gets detailed feedback straight away.
- Written assignments get a rubric score from AI.
- Coaches check every study post that AI drafts, and each post says so.
What changed
The course is live at masterclass.coachesdev.com. Its sign-in page says it is developed and managed by Autosterea.
We keep improving it. A trial page went live in July 2026.
