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

Which instruction was unclear?
How did you understand the time allowance?
What example would help before starting?

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: learners do not know whether answers can be changed.
2. The interpretation of time allowance reveals whether limits, pauses or submission timing are described consistently. Clarify the actual rules before participation, without treating respondents' preferred duration as evidence of assessment fairness.
3. Turn the requested improvement into a testable next step. One illustrative action is: explain navigation and submission rules.
