Robotic process automation is becoming increasingly prominent in the operations of businesses, especially for companies who are trying to stay current and keep pace with industry trends. Software robots, a component of robotic process automation, serve as valuable "coworkers" in automating various tasks. One such task involves the evaluation of written knowlegde exams, which is a part of assessing students' knowledge. The paper initially outlines methods for evaluating student knowledge, discusses robotic process automation and software robots, and later delves into the functionalities and procedures for collecting test exams. Additionally, it covers the testing of a software robot designed for grading knowledge exams within UiPath Studio. Furthermore, the paper presents surveys conducted among students to show their satisfaction with the process of grading written knowledge exams, as well as surveys among faculty members to gather their perspectives on the grading process and automation. In conclusion, potential challenges and enhancements in the use of such robots are explored, along with an analysis of costs and time savings. This analysis can serve as a guide for the future utilization of software robots in the process of grading knowledge exams.
