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

What timing information did you need?
Which alternative would you consider?
What update would help you plan?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: waitlisted learners cannot tell when availability is reviewed.
2. Acceptable alternatives reveal whether prospective learners need different timing, format or a related course. Describe verified options and their conditions, without treating expressed interest as an enrollment commitment or guaranteed place.
3. Turn the requested improvement into a testable next step. One illustrative action is: explain the next availability update.
