It's definitely a TREAT when a GOOGLE FORMS QUIZ does the grading for you!
If your Quiz has questions that you don't want graded, such as Name, Campus, etc., don't click on Answer Key for those questions. If no correct answer is chosen and no points are assigned to a question, it won't be graded. Also, you can save a little time creating your Quiz if you use the Google Forms Blank Quiz template. It can be found when you open Google Forms from the App Launcher.
