Psygon is an innovative new learning site where users can create and answer questions on a variety of subjects.  Jay Beaton Consulting built the site in Drupal 7 using Features and custom modules.

Innovative Algorithms 

Working with Psygon's management, we helped to create a patent-pending algorithm for selecting the best next question to ask a user.  As users answer questions correctly, they get more difficult questions.  If they start getting questions wrong, they'll see easier questions. 

Crowdsourcing to Rate Quality

The site also uses crowdsourcing to determine the quality of questions and shows the questions that users have upvoted as the best in a category.
