1. If you want to add a full section or a new unit, please describe precisely what you want to add before starting to write it so that we can review the idea, validate it or not, and guide you through the writing process.

Currently, quiz answers are always displayed in the same order, making the correct answer predictable. I would suggest randomizing the order of answer choices in the script to ensure variation in the placement of the correct answer for each question. I'll submit a PR implementing the fix.
