The paper describes a detailed procedure used to increase the reliability of online exams at a university. Background: The COVID-19 pandemic forced most universities to teach online. The most challenging part of online teaching is conducting online exams. Cheating in online exams is much easier, and many students may opt to cheat. Consequently, a fair assessment of the student performance becomes very challenging. Even though online teaching reduces teaching effectiveness, in many universities, the average GPA of students was observed to increase significantly.
