User Feedback Significantly more effective than printed atlases and textbooks in terms of helping students to gain a mind’s eye view and learn spatial relationships. “It adds quizzing abilities and multiple views which books don’t do.” “I would have loved to have [Annot3D] last semester.” “I wish I had had this for review on my anatomy exams.” from Anatomy Students
