This afternoon I received an email from a reader who wanted to know how to make a QR code for quiz that she had made in Google Forms. The process is rather straight-forward as it requires just one simple tool outside of Google Forms. To create a QR code for a Google Form simply click the "send" button in the upper-right corner of your Form, highlight the link and copy it. Then paste that link into the QR code generator on QR Droid.
