Instructions are forthcoming

Transclusion from Quizbank/Instructions_0:
These instructions are transcluded into all quizzes that are subpages of QB. They are written so they may be copied directly into a python test-generating code.

  1. *_ denotes magic words that the code looks for.
  2. The d_ series denotes Summer 2018 efforts. See Special:PrefixIndex/QB/d_
  3. The hidden message inside each question is required. I am currently using it to license the questions: <!--Public Domain--> (except for the questions I took from OpenStax. Those are attributed by stating the URL to the chapter that holds the example.)
