ABSTRACT
The article focuses on studying the success rate of NSA "Vasil Levski" students in the period of distance semester examinations in the conditions of the COVID-19 pandemic. The average exam scores between in-person and remote examination periods are compared. The following indicators were examined: the number of examinations held and the number of examinations passed by students;distribution in absolute and relative values of the scores obtained in the range according to the Bulgarian assessment scale;averages of the scores obtained. It has been found that the distance learning platform virtual.nsa.bg offers favorable conditions for quality online exams, which allow obtaining grades adequate to the knowledge shown by the examinees. The methodology by which test exams are created in the platform, and the security mechanisms developed when conducting exams significantly reduce the opportunities for examinees to artificially increase their grades without having demonstrated the required knowledge.
