Problems solved by technology

[0003] However, in scenarios such as after-school homework assignments and non-standardized exams, the answer sheets used are often unlimited answer sheets
Due to the non-standardization of unlimited answer sheets, many problems will be faced in automatic recognition
Therefore, for unlimited answer sheets, most of them still need to be manually corrected
