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

Which step felt out of sequence?
What knowledge did the next lesson assume?
What would help connect the lessons?

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: advanced exercises appear before the required explanation.
2. Assumed knowledge identifies a missing link between lessons rather than a general dislike of sequence. Add or signpost the relevant prerequisite, then check the transition without inferring that ordering alone caused learning outcomes.
3. Turn the requested improvement into a testable next step. One illustrative action is: move the prerequisite explanation before the exercise.
