For a long time Flubaroo has been one of my go-to recommendations for easy scoring of quizzes created in Google Forms. Today, Google made it easier than ever to have quizzes scored for you and to show students their scores. Now when you create a Google Form you can go into the Form settings and choose the quiz option. Within the quiz option you can choose to have your questions scored as students answer them. You can also choose to show students their scores as well as correct answers. See my screenshot below to learn where you can find the new quiz scoring options.

Applications for Education
The new automatic quiz scoring feature will make it easier to quickly deliver feedback to your students when they take multiple choice or true/false quizzes.

The automatic quiz scoring feature only supports multiple choice and true/false questions at this time. If you want to have short answer or fill-in-the-blank questions scored for you, you will need to use Flubaroo in Google Sheets.
