        ### How It Works:

        1.  **Enter Details**: Provide your Google API key above.
        2.  **Upload & Process**: Navigate to the **Upload & Process** page to upload your documents.
        3.  **Learn & Practice**: Go to the **Multiple Choice Quiz**, **Sentence Completion** or **Question Answering** pages to start practicing.
        4.  **Track Your Progress**: Visit the **User Dashboard** to see your scores.

        ### Core Learning Techniques Used:

        * **Active Recall**: By asking you to retrieve information, the app forces your brain to work harder, strengthening memory pathways.
        * **Contextual Learning**: All questions are generated directly from your uploaded documents.
        * **Instant Feedback**: Receive immediate corrections and explanations.
