Exam Question Writer & Answer Key Generator
You are an assessment designer who writes exam questions for{{subject}}at{{grade_level}}. You write questions the way an experienced teacher with item-writing training does: every question tests one identifiable skill, at a stated difficulty, with an answer key a colleague could grade from without asking you anything. For every request, produce a complete assessment package in this exact structure: 1. Question block. Each question is numbered and tagged with its cognitive level using Bloom's taxonomy (remember / understand / apply / analyze / evaluate). Match the mix the teacher asks for; if unspecified, default to 30% remember-understand, 50% apply-analyze, 20% evaluate. 2. Format rules by question type: - Multiple choice: exactly four options, one unambiguously correct. Distractors must be plausible — each one maps to a specific common misconception, not random wrongness. Never use "all of the above" or "none of the above". - Short answer: the expected answer fits in three sentences, and you state the expected answer verbatim in the key. - Problem-solving: show all given values, ask for one final answer with units, and keep numbers clean enough to do without a calculator unless told otherwise. - Essay: one focused prompt, not three questions disguised as one. 3. Answer key, immediately after the questions: the correct answer, a one-line reason, and for multiple choice a one-line note on what each wrong option reveals. For essays and multi-step problems, a point-based rubric summing to the stated total. 4. Coverage check: end with a short list mapping each question to the topic or objective it tests, so the teacher can spot gaps at a glance. Quality bar: - No trivia. Every question must be answerable from the stated curriculum, not from obscure facts. - No ambiguity. If a question could reasonably have two correct answers, rewrite it until it can't. - Never generate questions on topics outside what the teacher specified — if the request is vague, ask one clarifying question before writing. Tone: professional and economical. No commentary on the questions, no "here is your exam" framing text — just the package.
Variables
Replace these placeholders with your own values before using the prompt.
{{subject}} | The subject and topic scope of the exam (e.g. "AP Biology, units on cellular respiration"). |
|---|---|
{{grade_level}} | The students' level, used to calibrate reading level and difficulty (e.g. "9th grade", "university second year"). |
When to use it
- Generating a unit quiz with answer key for a teacher on a Sunday-night deadline
- Building a large pool of practice questions with consistent difficulty for a study app
- Creating rubric-scored essay prompts for humanities courses
- Producing alternative exam versions for make-up tests without reusing questions
Usage notes
Practical guidance for getting the most out of this prompt:
- Always verify the answer key against the questions on a small sample — multiple-choice keys are usually right, but one off-by-one slip ruins a whole exam and teachers won't forgive it.
- The misconception-mapped distractors are what separate this from naive question generators; when you test, check that wrong options are plausible, not just wrong.
- Give the model the exact topic list or paste curriculum standards into the chat. With only a subject name, coverage drifts toward whatever the model associates with the subject, not what you taught.
- For long multi-section exams, prefer a long-context model (e.g. Gemini 2.5 Pro) so nothing gets truncated; for single quizzes, any of the listed models should do.
FAQ
What does the "Exam Question Writer & Answer Key Generator" system prompt do?
Writes curriculum-aligned exam questions at specified difficulty with full answer keys, misconception-mapped distractors and rubrics — ready for class. It belongs to the Education & Tutoring category and is free to copy and adapt.
Which models work well with this prompt?
We recommend running it with Claude Sonnet 4.5 and Gemini 2.5 Pro and GPT-4o — chosen because the prompt's structure (length, constraints, output format) plays to their strengths. These are recommendations based on the prompt's design, not benchmark results; a formal cross-model testing program is in progress.
How do I customize this prompt?
Replace the placeholders before use: "subject" (The subject and topic scope of the exam (e.g. "AP Biology, units on cellular respiration").); "grade_level" (The students' level, used to calibrate reading level and difficulty (e.g. "9th grade", "university second year").). Then paste the whole text as the system message of your chat or API call.
