Optimizing the workflow for automatic quiz evaluation

Student examination is an important part of the educational process. Although various electronic testing and grading solutions have been developed and gained interest in the last years, classic paper quiz examination is still a preferred method of examination, due to the simplicity of implementation and low technical requirements. Korect is a complete solution for automatic test generation, processing and grading, with inline answer marks, and answer sheet processing using auto feed scanners and OCR detection. This paper presents the research performed for optimizing the preprocessing phase and the scan folder polling during the automatic verification flow. This research brings improved stability and performance for the Korect automatic quiz evaluation solution presented in the paper.
