Exam Samurai

Automatically generates exam questions by parsing and analyzing uploaded learning materials (textbooks, lecture notes, course documents) and mapping content to curriculum standards. The system uses NLP-based content extraction to identify key concepts, learning objectives, and difficulty levels, then generates questions that align with educational frameworks and learning outcomes specified by educators.

Generates diverse question formats (multiple-choice, true/false, short-answer, essay, fill-in-the-blank) with automatic difficulty level assignment based on Bloom's taxonomy or similar cognitive complexity frameworks. The system analyzes question content and learning objectives to assign appropriate difficulty ratings and can generate question variants at different difficulty levels from the same concept.

Automatically generates comprehensive answer keys for generated questions, including model answers, acceptable answer variations, and detailed grading rubrics. For subjective questions (essays, short-answers), the system creates point-based rubrics with criteria and exemplar responses, enabling consistent grading and providing guidance for instructors on how to evaluate student responses.

Allows instructors to customize generated exams by selecting/deselecting specific questions, reordering questions, adjusting difficulty distributions, modifying question text, and overriding auto-generated answers or rubrics. The system maintains a version history of customizations and enables saving custom exam templates for reuse across semesters or course sections.

Distributes generated and customized exams to students through multiple delivery channels (PDF download, LMS integration, web-based testing interface, print-ready formats). The system handles exam formatting, question randomization, and delivery-specific optimizations (e.g., responsive design for mobile testing, print layout optimization for paper exams).

Collects and analyzes student performance data on generated questions, calculating item difficulty indices, discrimination indices, and question effectiveness metrics. The system identifies problematic questions (those with unexpectedly low performance or poor discrimination) and provides instructors with data-driven insights for improving future exam versions.

Processes multiple learning materials simultaneously to generate exam banks covering entire courses or curricula. The system handles bulk uploads, manages dependencies between related materials (e.g., chapters in a textbook), and generates coordinated question sets that cover the full scope of materials while avoiding redundancy and maintaining consistent difficulty distribution across the entire exam bank.

Enables instructors to search and filter generated questions using semantic search (finding questions by meaning/concept rather than exact keyword match), learning objective alignment, difficulty level, question type, and custom tags. The system uses embeddings-based semantic matching to find conceptually similar questions and supports complex filtering queries combining multiple criteria.

Supports multiple instructors and teaching assistants collaborating on exam creation with role-based permissions (view-only, edit, approve, publish). The system tracks changes, enables commenting/feedback on questions, and manages approval workflows where exams must be reviewed before distribution to students.
