The analysis of the quality of knowledge of two groups of bachelors in the field of IVT of Pskov State University, who studied at different periods of time: before the outbreak of the pandemic and during its development, was carried out. The first group of students who entered the university in 2015 studied full-time, and the second, recruited in 2018, studied in a mixed full-time and distance form. The study of the quality of knowledge was conducted according to the average semester assessments of mathematical, general engineering and special disciplines. The evaluation sequences were considered as dynamic series. With the help of the constructed autocorrelation functions, the presence of a trend and cyclical fluctuations in them is established. A comparative analysis of the series of exam grades has established that the quality of knowledge of bachelors of the IVT direction in general engineering and special disciplines, both during full-time and mixed training, has no significant difference. The obtained results provide justification for the formation of effective options for the educational process. The work may be of interest to university employees who are associated with the development of new educational programs and with the planning of training sessions in the conditions of digitalization of society. The novelty of the work is due to the uniqueness of the situation that has developed in the Russian education system at the present time.
