Using a Form to create a quiz that has scoring / gets automatically scored?

I can't find anything in the documentation about scoring logic for Form answers. Some outside bloggers say it's possible to make a self-scoring quiz in Squarespace. Have you done this, or do you know where it's described in detail? 

My ideal case is a "personality quiz" which puts the user into a category (not giving them a score from 0-100 as would happen on a knowledge quiz)

thanks!
