"In case you have not seen it yet, Google Forms has a new option called Google Quizzes that has some really cool features--features that no longer require the use of Flubaroo. And the best news? The forms you may have already created as quizzes can be switched to the new quiz format with the change of one simple setting. No retyping! And, whereas with Google Forms/Flubaroo, you could not collect student emails to send them their quiz results because this also allowed them to send themselves their answers to forward onto others, now you can collect those emails. There are additional settings that let you choose what options students have available and when you release quiz results. Plus, the data that Google Quizzes provides you with student responses is incredibly helpful and much easier to read than Flubaroo! "
