I just made a video that is available in three places:

Lake Campus Symposium: Creating a bank so students won't break the bank
https://bitbucket.org/Guy_vandegrift/qbwiki/wiki/Home/
The conversion to LaTeX should make this bank more compatible with VLEs
Quizbank - Quizbank/Python/LaTex - Category:QB/LaTeXpdf - QB - edit news
Students with minimal Python skills can now write numerical questions

-
• 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.
