  title: Google Forms Build and Grade a Quiz
  summary: Create a form, switch it into quiz mode with a graded question, publish it, and read scored submissions.
  description: >-
    A quiz is a form with grading turned on, which means it is built through the
    same create and batch update path but with a distinct payload: quiz settings
    are switched on through updateSettings, and each question carries a grading
    block holding its point value, correct answers, and feedback. This workflow
    builds that quiz, publishes it, and then reads responses back for the total
    score the service computes on submission. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
