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.
