Create a Quiz

Host a JSON question file anywhere (GitHub raw, Gist, jsonbin…), paste the link, and get a shareable quiz link.

Quiz title JSON file URL

The JSON must be an array of { question, options, answer, id } objects. Questions support Markdown + KaTeX.

How to host your JSON on a GitHub Gist

Go to gist.github.com and sign in.
Set the filename to something ending in .json (e.g. quiz.json).
Paste your JSON array into the file content box.
Click “Create public gist” (it must be public so the quiz can be fetched).
Click “Create public gist”, then copy the URL — either the gist page link (https://gist.github.com/<user>/<id>) or, for an exact-version link, the “Raw” URL (https://gist.githubusercontent.com/<user>/<id>/raw/…/quiz.json).
Paste either URL into the field above.

Tip: a plain gist page link works too — the quiz page auto-resolves it to the raw file. A Raw URL with a commit hash is pinned to that exact version; if you later edit the gist, grab a fresh Raw link.

Have raw questions?

Copy this prompt, paste it into any AI (ChatGPT, Claude…) with your questions, then host the JSON it returns and paste the link above.

You are a quiz formatter for the "MA Quiz" app. Convert the questions I give you into ONE valid JSON array.

Reply with NOTHING but the JSON array inside a single fenced code block tagged json, like:
```json
[ ... ]
```
Pretty-print it with 2-space indentation so it is easy to read, and make sure it is well-formatted and strictly valid (no commentary before or after the fence).

Each element must follow this exact schema:
{
  "question": "the question text",
  "options": { "a": "option A", "b": "option B", "c": "option C", "d": "option D" },
  "answer": "a",
  "id": 1
}

Rules:
- "answer" is the key ("a", "b", "c", or "d") of the correct option.
- Multiple-choice questions use options "a" through "d" (use fewer keys only if there are fewer choices).
- True/False questions use exactly two options: { "a": "True", "b": "False" }.
- "id" is a unique integer starting at 1 and incrementing by 1 per question.
- You may use Markdown (Obsidian flavor) in any text: **bold**, *italic*, lists, tables, ==highlight==, `inline code`, fenced code blocks, and math with $inline$ or $$block$$ (KaTeX).
- Keep the original wording and any code/formatting. Do not invent answers; if the correct answer is not given, work it out.

=== CRITICAL: JSON backslash escaping (the #1 cause of broken quizzes) ===
A lone backslash is ILLEGAL in JSON. Every backslash must be part of a valid escape. Inside any string value:
- LaTeX commands need a DOUBLE backslash. Write "\\frac", "\\sqrt", "\\int", "\\pi", "\\alpha" — NEVER "\frac" or "\pi" (a single "\f" silently becomes a form-feed and corrupts the file).
- A new line inside a fenced code block is written as \n (backslash + the letter n).
- A double quote inside text is written as \" (backslash + quote).
- Never use curly/smart quotes. Use straight double quotes " only.
- The whole output is ONE array: it must start with [ and end with ]. Do not forget the opening bracket.
- After writing, mentally JSON.parse it: if any string contains a single backslash that is not \n, \t, \", or \\, it is wrong.

=== EXAMPLE (study this exact output; note the doubled \\ in LaTeX, the \n and \" inside the code block, and the wrapping [ ]) ===
[
  {
    "question": "What is the output of this code?\n\n```python\nfor i in range(3):\n    print(i)\n```",
    "options": { "a": "0 1 2", "b": "1 2 3", "c": "0 1 2 3", "d": "Error" },
    "answer": "a",
    "id": 1
  },
  {
    "question": "Evaluate the Gaussian integral:\n\n$$\\int_{0}^{\\infty} e^{-x^2}\\, dx$$",
    "options": { "a": "$\\frac{\\sqrt{\\pi}}{2}$", "b": "$\\sqrt{\\pi}$", "c": "$\\pi$", "d": "$\\frac{\\pi}{2}$" },
    "answer": "a",
    "id": 2
  },
  {
    "question": "Which command prints text in JavaScript? Note the escaped quotes: `console.log(\"hi\")`.",
    "options": { "a": "```js\nconsole.log(\"hi\");\n```", "b": "```python\nprint(\"hi\")\n```", "c": "```php\necho \"hi\";\n```", "d": "```cpp\ncout << \"hi\";\n```" },
    "answer": "a",
    "id": 3
  }
]

Final reminder: reply with ONLY the ```json fenced block containing the strictly-valid, 2-space-indented array (straight double quotes, every backslash escaped, wrapped in [ ]). When I copy that block I will save only the JSON inside the fence.
