Do you have a quiz or a test in a Google Doc, and you want to quickly move it to a Google Form? You can do this with the Add-on called Doc to Form.
Open up your quiz or test in gDocs, and select the Add-ons menu. If you don’t already have Doc to Form, go to Get Add-ons and install Doc to Form. Once it is installed, it will appear in your list of Add-ons. (You only need to do this once.)
