You can remove any question or page directly from inside the Lantern quiz editor.
Here’s how:
Open your quiz in the Quiz Builder.
Click on the question or page you want to remove from the list on the left.
Look at the bottom-right corner of the editor panel.
Click Remove Question (or Remove Page, depending on the page type).
The question or page will be permanently removed from the quiz. This works for all page types (questions, opt-in pages, transition screens, etc.).
Once removed, the page cannot be recovered unless you recreate it. If you’re unsure, you can also clone a question first before deleting it.
