Padikkam - Content Repository

Padikkam is a completely free offline app with all the features you need to prepare for KEAM. This repository serves as the cloud backend for the app, hosting all the Past Year Question papers (PYQs) and other public assets. The app dynamically syncs these files so students can get the latest papers without needing an app update.

🤝 Contribution

We welcome contributions from the community! If you have recent or missing question papers, you can add them to this repository. You can generate the JSON file manually, or use an AI tool (like ChatGPT, Gemini, or Claude) to convert raw text into our JSON structure. The final result must be accurate and strictly follow the format below.

How to Contribute

Best Practice: It is highly recommended that you add the new paper AND update the index.json file in the same Pull Request. This ensures your contribution is complete and ready to be delivered to students immediately upon merging. As a repository maintainer, this saves a lot of time!

1. Fork the repository to your GitHub account.
2. Create the folder structure for the new paper. Papers are organized by year and date: pyq/{Year}/{MonthDay}/paper.json (Example: pyq/2026/April17/paper.json)
3. Create the paper.json file.
4. Update index.json in the root directory to include your new paper.
5. Submit a Pull Request (PR) to this repository.

File Formats

1. paper.json (The Question Paper)

This file goes inside the specific folder for the date (e.g., pyq/2026/April17/paper.json). Ensure that correct_option is 0-indexed (i.e., Option A = 0, Option B = 1, Option C = 2, Option D = 3, etc.).

{
  "id": "paper_2026_april_17",
  "title": "2026 April 17",
  "version": 1,
  "questions": [
    {
      "id": 1,
      "subject": "Mathematics",
      "text": "Let A and B be two subsets of a universal set U. If n(U) = 116, n(A ∪ B) = 99, n(B) = 61 and n(A ∩ B) = 28, then n(A') is equal to",
      "has_image": false,
      "image_path": "",
      "options": [
        "47",
        "45",
        "53",
        "48",

      ],
      "correct_option": 4
    },
    {
      "id": 2,
      "subject": "Mathematics",
      "text": "Let f(x) = sin⁻¹x and g(x) = x - 2. To define the composite function f ∘ g, the largest domain of g(x) has to be",
      "has_image": false,
      "image_path": "",
      "options": [
        "[2,5]",
        "[1,3]",
        "[0,2]",
        "[-1,3]",
        "[-3,3]"
      ],
      "correct_option": 1
    },
    {
      "id": 3,
      "subject": "Mathematics",
      "text": "Let f(x) = 10/(7 + 4sin x + 3cos x), x ∈ R. Then the range of the function f is",
      "has_image": false,
      "image_path": "",
      "options": [
        "[1,5]",
        "[5,10]",
        "[1,10]",
        "[1,2]",
        "[5,10]"
      ],
      "correct_option": 0
    }
  ]
}

2. index.json (The Paper Directory)

After creating your paper.json, add an entry to the papers array inside index.json located at the root of the repository.

{
  "min_required_version": 1,
  "banner_message": "",
  "papers": [
    {
      "id": "paper_2026_april_17",
      "title": "2026 April 17",
      "year": 2026,
      "version": 1,
      "url": "pyq/2026/April17/paper.json"
    },
    {
      "id": "paper_2026_april_18",
      "title": "2026 April 18",
      "year": 2026,
      "version": 1,
      "url": "pyq/2026/April18/paper.json"
    }
  ]
}

Tips for AI Generation

If you use an AI to generate the JSON from a PDF or image:

• Prompt: “Convert these questions into a JSON array matching this format: { "id": 1, "subject": "Mathematics", "text": "...", "has_image": false, "image_path": "", "options": ["A", "B", "C", "D"], "correct_option": 0 }. The correct_option must be the 0-based index of the right answer.”
• Always verify that the equations and symbols (like sin⁻¹x or ∪) were correctly parsed by the AI before submitting your pull request.
• Ensure the id of each question is sequential and unique within the paper.
