# QB/a25GeometricOptics vision

* 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)
The enrollment key for each course is 123. They are all is set to practice mode, giving students unlimited attempts at each question. Instructors can also print out copies of the quiz for classroom use. If you have any problems leave a message at user talk:Guy vandegrift.
* Latest essay: MyOpenMath/Pulling loose threads
* Latest lesson: Phasor algebra
