Moodle Quiz Scripts on GitHub: Why They Fail and Why They're Risky

Search GitHub for "Moodle quiz" and you will find dozens of userscripts and bots promising automatic answers. Most have a handful of stars, an old last update and a list of open issues saying "doesn't work anymore". Here is why, and why running them can be a bad idea even when they do work.

Why most scripts are broken

Moodle releases new versions twice a year, and the structure of quiz pages changes between versions. On top of that, every school uses its own theme, plugins and settings. A script that looks for a specific HTML element on one site often finds nothing on another. Scripts also tend to rely on question-and-answer databases built from other students' attempts, which rarely match quizzes that use random questions and shuffled answers.

The security problem

A userscript runs inside your logged-in Moodle session. That means it can:

• Read everything on the page, including your name, grades and messages.
• Send requests to Moodle as you.
• Send data to an outside server.

Most scripts are harmless hobby projects, but you cannot tell without reading the code. A malicious or careless script could leak your session or personal data. Installing random code into your university account is a real risk.

The account problem

Automated scripts can send requests faster or in different patterns than a human. That can cause errors in your attempt and creates entries in Moodle's logs that look nothing like normal use. Teachers and administrators do look at logs when something seems off. See features Moodle teachers use to spot cheating.

The integrity problem

Safer ways to get help

If what you actually want is faster feedback on questions, there are safer options:

• The quiz review page and feedback after submitting.
• AI chats to explain concepts and generate practice questions.
• A published extension with a clear privacy policy, like TrustStudy, which only sends a question when you press the shortcut and is designed for studying.

If you are curious about the code

Reading how Moodle works is a great way to learn web development. Moodle is open source, and its documentation explains how quizzes, question types and grading work. Exploring that on a local test install is legal, safe and educational. Just keep it away from your school's site.

The takeaway

GitHub quiz scripts are mostly broken, sometimes dangerous and always a risk to your academic record when used on real quizzes. Your time is better spent on study methods that actually work.
