If your survey is still "in progress" (you haven't submitted it yet):
Go to your "My Data" page
In the survey section, find the survey you want to make changes to
Click the 3 dots to the right of the survey name and select "resume survey"
You will land on the survey page and should resume wherever you left off
You can use the "previous" button to review responses to questions you already answered and edit them
If you already submitted your survey:
Go to your "My Data" page
In the survey section, find the survey you want to make changes to
- Click the 3 dots to the right of the survey name and select "delete survey". You have to delete a submitted survey in order to make changes.
- Now go back to the study the survey was in (you can get here from your dashboard, scroll down to the "studies" section and find the study name in the list, click it to go to the study page)
- On the study page, go to the data requests section, find the survey and now you should see a "begin" button with it and can retake it. It will not have any of your previous responses in it since you deleted the previous submission in order to redo it.
