WSUQ&T is a open source web-based questioning and tutoring system developed for university level physics by Washington State University Physics under the guidance of Dr. Tom Dickinson. Developed for Linux operating systems using Apache HTTP servers, it allows instructors to create questions and administer quizzes online for their courses. It includes equation, numerical, multiple choice, fill in the blank, and one sentence short essay question types. It may also be used in other disciplines with some modification.
