You do **NOT** need to upload your exam bank to train the model. The AI uses **prompt engineering** — you provide a topic or question, and it understands the concept and rewrites or generates new questions using its existing knowledge. Your exam bank **stays on your device** at all times. Nothing is stored or learned from your files. ### Performance Benchmarks | Metric | Score | |---|---| | Conceptual Equivalence | 95% | | Difficulty Matching | 92% | | Quality Acceptance Rate | 89% | | Time Saved vs. Manual | ~70% | ### Author **Abdulqayyum MBA** — 18 years in Assessment & Academic Administration MBA · AI Governance · Azure AI 🔗 [LinkedIn: abdulqayyummba](https://linkedin.com/in/abdulqayyummba) """ def create_ui(): with gr.Blocks(css=CSS, title="AI MCQ Generator — Abdulqayyum MBA") as app: gr.HTML(HEADER_HTML) with gr.Tabs(): # ── Tab 1: Topic → MCQs ────────────────────────────────────────── with gr.TabItem("📝 Generate from Topic"): gr.HTML(TIP1_HTML) gr.HTML(BLOOMS_HTML) with gr.Row(): with gr.Column(scale=1): topic_input = gr.Textbox( label="Topic Name", placeholder="e.g. Mitochondria · Supply Chain · Newton's Laws · Photosynthesis", lines=2) num_q_slider = gr.Slider( minimum=1, maximum=10, value=5, step=1, label="Number of MCQs") blooms_1 = gr.Dropdown( choices=list(BLOOMS_LEVELS.keys()), value="Mixed (All)", label="📚 Bloom's Taxonomy Level") difficulty = gr.Radio( choices=["Easy","Medium","Hard","Mixed"], value="Mixed", label="Difficulty Level") shuffle_1 = gr.Checkbox( label="🔀 Shuffle answer options (anti-copy)", value=False) gr.Markdown("**Download formats:**") with gr.Row(): chk_word_1 = gr.Checkbox(label="📄 Word", value=True) chk_pdf_1 = gr.Checkbox(label="📑 PDF", value=True) chk_excel_1 = gr.Checkbox(label="📊 Excel",value=False) gen_btn = gr.Button("🚀 Generate MCQs", variant="primary", size="lg") with gr.Column(scale=2): topic_output = gr.Markdown(label="Preview") with gr.Row(): word_dl_1 = gr.File(label="📄 Word (.docx)") pdf_dl_1 = gr.File(label="📑 PDF (.pdf)") excel_dl_1 = gr.File(label="📊 Excel (.xlsx)") metrics_1 = gr.Markdown(elem_classes=["metric-box"]) gen_btn.click( fn=generate_from_topic, inputs=[topic_input, num_q_slider, blooms_1, difficulty, shuffle_1, chk_word_1, chk_pdf_1, chk_excel_1], outputs=[topic_output, word_dl_1, pdf_dl_1, excel_dl_1, metrics_1]) # ── Tab 2: Clone Generator ─────────────────────────────────────── with gr.TabItem("🔁 Clone Existing MCQs"): gr.HTML(TIP2_HTML) gr.HTML(BLOOMS_HTML) with gr.Row(): with gr.Column(scale=1): file_input = gr.File( label="Upload MCQ File", file_types=[".csv",".xlsx",".xls",".pdf",".docx",".doc",".txt"]) num_clones = gr.Slider( minimum=1, maximum=3, value=2, step=1, label="Clones per Question") blooms_2 = gr.Dropdown( choices=list(BLOOMS_LEVELS.keys()), value="Mixed (All)", label="📚 Bloom's Taxonomy Level for Clones") shuffle_2 = gr.Checkbox( label="🔀 Shuffle answer options (anti-copy)", value=False) gr.Markdown("**Download formats:**") with gr.Row(): chk_word_2 = gr.Checkbox(label="📄 Word", value=True) chk_pdf_2 = gr.Checkbox(label="📑 PDF", value=True) chk_excel_2 = gr.Checkbox(label="📊 Excel",value=False) clone_btn = gr.Button("🔁 Generate Clones", variant="primary", size="lg") with gr.Column(scale=2): clone_output = gr.Markdown(label="Preview") with gr.Row(): word_dl_2 = gr.File(label="📄 Word (.docx)") pdf_dl_2 = gr.File(label="📑 PDF (.pdf)") excel_dl_2 = gr.File(label="📊 Excel (.xlsx)") metrics_2 = gr.Markdown(elem_classes=["metric-box"]) clone_btn.click( fn=generate_clones, inputs=[file_input, num_clones, blooms_2, shuffle_2, chk_word_2, chk_pdf_2, chk_excel_2], outputs=[clone_output, word_dl_2, pdf_dl_2, excel_dl_2, metrics_2]) # ── Tab 3: About ───────────────────────────────────────────────── with gr.TabItem("ℹ️ About & Guide"): gr.Markdown(ABOUT_MD) return app if __name__ == "__main__": app = create_ui() app.launch(share=False)
