For this reason, the implementation of the online preparatory course to enter engineering and level their knowledge, considering the previous situation, becomes significant as it impacts the training of the engineer. To apply the online propaedeutic course, a survey was carried out before and after it in Google Form with the aim of knowing the perception of the use of this modality of the course. What led to relate what was specified in other studies where it is expressed that today's youth are digital natives, but without a doubt we are also sociable by nature, so we need to interact to learn and relate, which requires the intervention and guidance of a teacher.
