The Simple note quiz plugin helps users create interactive quizzes directly from their notes in Obsidian. By parsing questions and answers formatted in the note, it generates a quiz that users can take to reinforce their learning. Questions are identified by customizable markers (e.g., question marks), and answers are listed beneath them. Users can mark answers as correct or incorrect, enabling them to track their progress and identify areas needing improvement. The plugin updates marks as quizzes are taken and allows users to clear or review them for better organization and learning efficiency.
