Just in time for the start of the school year, Google Forms released a new update. You can now quickly create self-graded quizzes in Google Forms without ANY add-ons like Flubaroo!
Quizzes in Google Forms doesn't have all of the bells and whistles that Flubaroo has, but it's great for informal formative assessments. Eric Curtis has a great comparison of Google Forms Quizzes and Flubaroo on his blog. He also included written directions on how to setup self-grading quizzes in Forms.
