Is the STS drone exam hard?
Honest answer: STS is significantly more demanding than A1/A3 or A2 — but absolutely passable with the right study structure.
Why STS feels harder
- Double the questions vs A2
- More scenario-based risk assessment
- Specific category terminology
- Less intuitive for hobby pilots
What makes the difference
Candidates who pass use topic-based learning first, then progressive timed simulations. Cramming regulations without practice questions rarely works.
