If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which reminder helped you prepare?
What information was missing?
What reminder timing would help?

Author notes / illustrative keys where applicable:
1. Identify the reminder whose verified information enabled preparation and what it supplied. Preserve the helpful detail while checking missing information in other reminders separately.
2. Missing reminder information identifies the preparation detail learners could not recover from the message. Add relevant verified dates, locations or prerequisites, while distinguishing message clarity from proof that reminders increase attendance.
3. Identify when preparation information must arrive to allow the learner to act before the course. Compare the requested notice period with actual arrangements rather than assume clicks show readiness.
