I write google forms add-on for statistical analysis of responses (average, median, standard deviation, discriminative efficiency and so on).
Is it possible to get score of user's answer from gs code? Or maybe exists the method for checking user's response?
please research before asking. Just a quick glimpse at the documentation shows the entry for
getResponses()
which shows what you can do with the formResponse object. As you can see you can get every single part of the response.
