After a week, the measures of the national and county headquarters recommended "work from home". Under these conditions, many years of investing in one's own knowledge helped a lot. In recent years, we have learned a lot about the application of digital technology in teaching and we have our own expert for all our digital challenges. Our Erasmus+ projects aimed to introduce new teaching methods (eg "Flipped classroom"), use digital resources and online communication platforms to raise the quality of teaching and motivate adult learners to learn. However as it turns out, they were also a good "preparation" for the "COVID-19 situation".
