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

What do you expect to learn?
Which prerequisite is unclear?
What information would help decide to register?

Author notes / illustrative keys where applicable:
1. Identify the topic or practical task the reader expects the webinar to explain. Compare that expectation with the verified session scope before registration, keeping prerequisites separate from learning promises.
2. An unclear prerequisite reveals whether intended participants can judge the webinar's relevance before registering. Explain actual prior knowledge or preparation requirements, without assuming self-reported familiarity guarantees readiness or learning outcomes.
3. Turn the requested improvement into a testable next step. One illustrative action is: explain prerequisites and session scope.
