The paper presents a comparative survey regarding the student behavior and perception of the educational process, before, during and after the pandemics. The study was done on subjects in the second year of study, where the author and the team teaches. Student comments and evaluations are discussed over three periods of time: before pandemics (moderate), during pandemics (critical) and after pandemics (positive). The educational process was evaluated in terms of percentages of the qualifications reflecting the students satisfaction degree in respect to the teaching methods for different curricula. The conclusion showed that before the pandemics while the scholar process was a moderate classical face-to-face one with medium results, during pandemics the whole process was stressful, impersonal and negatively perceived, while after pandemics a collaborative human interaction was developed. A crisis situation determined the creation of a positive learning environment, where human interaction proved to be very important. The skills we obtained while online teaching were useful but complementary to the collaborative on-site learning process.
