Students don't mind taking tests when I use Quia. Test grades have improved when I use my quizzes as reviews one day and then have them do it the next day for a grade. I like the fact that a student can re-do a quiz if I am using it for review until he or she gets all questions right. It is nice that they see the correct answer when they miss a question.
