One of the greatest benefits of Quia as a teacher is to review the statistical info. If I see that a large percentage of the students missed a question, I can re-evaluate how I taught that concept. This has led to improvements over the years. I use Quia for ALL quizzes... and this year I am starting to use it for labs. Too many favorite features to mention...
