I came up with a few work arounds that you might want to try. Each option requires that you make a separate quiz for each section. For example, if you wanted three sections for your quiz, you would need to create three different quizzes.
- Idea # 1 - Create individual quizzes in Google Forms, but link everything in a Google Doc.
- Idea # 2 - After each "quiz" or section is finished, created a custom message with a hyperlink to take your next "quiz" or section.
