QMR organizes your grading work around four tightly connected ideas: the **exam**, the **answer sheet**, the **scan request**, and the **submission**. Once you understand how they relate to each other, every action in the dashboard — creating an exam, printing sheets, uploading a photo, reading results — will feel predictable. You do not need to know anything about the underlying technology; QMR handles the recognition and scoring automatically. The workflow begins before exam day. You create an exam in the dashboard, enter the correct answers for each question, and choose an answer sheet template. QMR generates a PDF of ready-to-print answer sheets, one per student, each containing a unique QR code. The QR code encodes which exam and which round the sheet belongs to, as well as the individual student's identity. Students fill in their chosen answers on the sheet using a pen, just as they would on any paper test. After the exam, you open the **Scan** section of the dashboard, take a photo of each completed sheet with your smartphone camera, or upload a batch PDF if you have already scanned the sheets on an office scanner. QMR reads the QR code to identify the exam, the round, and the student without any manual lookup, then extracts each marked answer using AI image recognition. Within seconds, a **submission** appears in the dashboard — one graded result per student per round — showing the total score and the answer chosen for every question. Because grading is automatic and submissions appear in real time, you can move straight from collecting papers to reviewing results. The **Statistics** section aggregates all submissions into score distributions, per-question accuracy rates, group breakdowns by class or round, and answer-choice distributions. At any point you can export the full dataset to Excel for your own analysis, or share individual results with students through the QMR student app. Learn how exams, problem sets, rounds, and answer sheet templates fit together.
