To add an answer key to Google Forms, you need to know how to create a Google Form quiz. Once you have created your form, go to the "Settings" cog in the top right-hand corner and select the "Make this a quiz" option. This will allow you to add answer keys, point values, and automatic feedback to your questions.

Go to Google Forms and Create a Blank Google Form. Now, add the data or the survey to the document and add questions. Click on the setting on the right side of responses to open the form’s settings. Now enable the Make this a quiz option available in the Google Forms settings.
