Flubaroo has always been one of my favorite and most used scripts for Google Spreadsheets. It allows you to have your quizzes, created using Google Forms, automatically graded. It also includes features for emailing results to students and much more. The only downside was that you had to install this script EVERY time you created a quiz. Well the new add-ons feature in Google Spreadsheets has finally resolved this issue! Now, when you install the Flubaroo add-on, you can always find Flubaroo available in every spreadsheet. When you create a quiz, simply click Add-ons>Flubaroo>Grade assignment and you can begin using the powerful features of Flubaroo.

Check out a brief tutorial below on how to create quizzes using Google Forms.
