GoSurvey has a very different feature called as “Partial Form Completion”, here the user can save the form in between the completion.
How it works?
In general cases user has to complete the whole form , even though some answers are missing and the next day user will again have to fill the whole form although some questions were answered. So at the end there will be two forms of the similar respondent.
Partial form completion works as , the user can save the form if the answers are missing and the next day it can edit the same form from the data and can start accomplishing it further. This feature can overcome the duplication of surveys and can give the accurate result of the data.
