The aim of the article is to compare the results of the study before and during the pandemic. It is also a reflection on what we experienced and how we undertook pedagogical work with students in critical teaching conditions. The coronavirus pandemic brought about an unexpected and rapid change in all aspects of education. It seems like neither the teachers nor the students were ready. The article describes how the transition to online teaching took place overnight. It describes how technical subjects were taught and examined in a new online environment. This is about how the students evaluated that form of education in the subjects of ‘Heat Treatment and Metal Surface Treatment’ and ‘Material Science I’. The results of the study confirmed that even in the conditions of complete separation in the social and work contact, it is possible to study by conscientious preparation and self-access.
