{Construction of a digital exam grading system using \TeX} {Yusuke Terada} {At our school in Japan, large-scale paper exams are held on a regular basis. The number of examinees is enormous, and the grading must be finished within a short period of time. Improving efficiency was strongly needed. So I developed a digital exam grading system using \TeX. \TeX\ and related software play a core role in the system, co-operating with iPad and Apple Pencil. In this presentation, I would like to present how \TeX\ can be effectively applied to constructing the digital exam grading system. I will also mention the unexpected difficulties that I faced in the actual large-scale operations and the way I have overcome them.}
