I want something like this: http://gamebrahma.com/mod/question/assessment.php

There's an existing module that you may probably be able to customize to suit our purposes here: http://community.elgg.org/pg/plugins/webcubes/read/252928/survey-plugin

The user should be able to take the test and the results should be published to his profile as a badge (or badges, as the case may be).

The questions, weighted scores, and interpretations are in an Excel file for you to use.
