# Case 23: Exam Paper Generation

## Scenario

Rachel teaches 8th-grade physics across three classes. Before each exam she balances question types (multiple choice, fill-in, lab, calculation), difficulty (60% basic, 30% medium, 10% advanced), and coverage. Her old process: dig through question banks, pick questions, format, print. One exam took three hours. Three classes meant three exams.

## File Prep

Rachel keeps materials in one folder:

```plaintext theme={null}
Desktop/8th-Physics-Exam-Materials/
├── Curriculum-Standards-8th-Physics.pdf
├── Ch1-Motion-Notes.docx
├── Ch2-Sound-Notes.docx
├── Ch3-Phase-Changes-Notes.docx
├── Past-Exam-Reference.docx
└── Class-Scores-Last-Exam.xlsx (optional, for weak areas)
```

<Steps>
  <Step title="Select your folder">
    Select `8th-Physics-Exam-Materials`.
  </Step>

  <Step title="Enter exam requirements">
    ```plaintext theme={null}
    Using the notes and curriculum in this folder, create 3 exam variants for 8th-grade physics:
    1. Scope: Chapters 1–3
    2. Structure: 10 MC (3 pts each) + 8 fill-in (2 pts each) + 2 lab (16 pts) + 2 calculation (14 pts), 100 pts total
    3. Difficulty: 60% basic, 30% medium, 10% advanced
    4. Same coverage across all 3, different questions
    5. Include answer key and rubric for each
    6. Use last exam scores to add more questions on weak topics (e.g., phase change graphs)
    7. Output as Word, print-ready
    ```
  </Step>
</Steps>

## What QoderWork Did

QoderWork read the notes and standards, produced three balanced exams with different questions, full answer keys and rubrics. It used last exam data to add extra questions on weak areas like phase change graphs.

## Ongoing Use

Before each exam: add new chapter notes, then say "Extend to Chapter 4 and generate new exams in the same format." For finals: "Use all exam scores to generate personalized weak-topic practice per student."

## Key Metrics

| Metric    | Result                             |
| --------- | ---------------------------------- |
| Coverage  | All topics represented             |
| Control   | Difficulty and structure specified |
| Volume    | 3 exams in one run, no repeats     |
| Targeting | Uses score data for weak areas     |

## Pro Tips

Use **folder organization + precise prompt parameters**.

Rachel: (1) put notes, standards, past exams, and scores in one folder, and (2) specified exact numbers—question counts, point values, difficulty percentages, and weak topics. **Concrete numbers in the prompt make output predictable.**
