- Quizbank now resides on MyOpenMath at https://www.myopenmath.com (although I hope Wikiversity can play an important role in helping students and teachers use these questions!)
- At the moment, most of the physics questions have already been transferred. To see them, join myopenmath.com as a student, and "enroll" in one or both of the following courses:
- Quizbank physics 1 (id 60675)
- Quizbank physics 2 (id 61712)
- Quizbank astronomy (id 63705)
