# QB/d cp2.gaussC

< QB

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.

• 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)

-
• This is a conceptual quiz that should not require a calculator. Even thought there are only 6 questions, we can use these six as templates for students to modify in the first week of Phy1050 because we will also introduce [[QB/d_zTemplateConceptual, which will introduce students to the script used to create and modify these Quizbank quizzes.

See special:permalink/1945717 for a wikitext version of this quiz.
