Practice Tests

You do not have to type a single question yourself, because Google’s own free helper will write them for you if you ask it in the right way.

1. Open Google’s helper. Go to gemini.google.com in another tab and sign in with your ordinary Google account.
2. Copy the words below and paste them in. Change the subject and the number of questions to whatever you are studying.
3. Download the file it makes. The words below ask it for a file you can download called questions.json, so press its download button and keep the name it comes with.
4. If it will not give you a file, make one yourself. Copy the JSON it wrote, paste it into a plain text editor such as Notepad, and save it with a name ending in .json.
5. If it writes the questions out as ordinary writing instead, ask again. Reply to it with: Give me that again as a downloadable JSON file, in the shape above, with nothing else in your reply.
6. Read what it gives you. A helper like this gets things wrong sometimes, so check the answers against your own book before you trust them.
7. Upload that file here. Use the box further down this page, and your questions become a test you can take as many times as you like.
8. Use it as a study tool. The night before a test, or for the couple of days before one, go over the questions again and again until you get all of them right every time and you feel sure you know them, and you are guaranteed to at least get a good grade.

These are the words to paste in, and the first line is the one that matters most, because a helper asked for questions will usually write them out as ordinary writing unless it is told not to.

Give me a JSON file I can download, called questions.json, holding only the JSON below and nothing else. If you cannot make a file, reply with the JSON on its own instead: no explanation, no headings, no numbering and no code fences, with { as the first character of your reply and } as the last.

Write 20 multiple-choice questions about photosynthesis for a 9th grade student.

Use exactly this shape:

{
  "title": "Photosynthesis",
  "questions": [
    {
      "question": "the question",
      "choices": ["first choice", "second choice", "third choice", "fourth choice"],
      "answer": "the choice that is right, written out in full",
      "explanation": "one sentence saying why"
    }
  ]
}

Every question needs all four of those parts, and "answer" has to be one of that same question's own choices, copied word for word. Reply with the JSON and nothing else.

For more accurate questions: ask across several trusted sources

A helper sometimes makes up a wrong answer, which is called a hallucination, and if you memorize that wrong answer you learn the wrong thing. You can make the questions much more trustworthy by telling the helper to check every question, choice and answer against at least three trusted sources before it writes anything — for example your official course outline, a well-known textbook, and a respected study standard for your subject. Change the subject, the level, and the three sources below to your own, and read the full post about this “multiple authorities” way of asking, which has a worked physics example.

Act as an expert teacher and careful test writer for [SUBJECT, for example 11th grade biology]. Your goal is to write an accurate, hallucination-free JSON practice test I can download.

Before you write any question, choice or answer, cross-reference and correlate every fact against at least three trusted sources for this subject, such as:
1. [Source one, for example my OpenStax textbook]
2. [Source two, for example the AP or IB course standard]
3. [Source three, for example a second well-known textbook publisher]

Every correct answer and explanation must be supported by those sources. The wrong choices should be common mistakes students really make, but must be clearly wrong by the facts.

Write exactly 15 multiple-choice questions about [TOPIC] for a [LEVEL, for example 11th grade] student.

Give me a JSON file I can download, called questions.json, holding only the JSON below and nothing else. If you cannot make a file, reply with the JSON on its own instead: no explanation, no headings, no numbering and no code fences, with { as the first character of your reply and } as the last.

Use exactly this shape:

{
  "title": "[TOPIC] Practice Test",
  "questions": [
    {
      "question": "the question, with any units and limits stated",
      "choices": ["first choice", "second choice", "third choice", "fourth choice"],
      "answer": "the choice that is right, copied word for word from its own choices",
      "explanation": "one or two sentences saying why, naming the rule or source it comes from"
    }
  ]
}

Write any formulas in plain text, like F = ma, so they show up cleanly. Every question needs all four parts, and "answer" has to match one of that same question's own choices word for word. Reply with the JSON and nothing else.
