However, applying them in a short time is not easy, for many factors even impossible such as revise the curriculum, prepare materials, train lecturers and students, prepare the related infrastructure. Therefore, we make many customizations to adapt to the current situation as well as reuse the most available resources. Emergency distance learning is an effective way to deal with diseases. However, exploring its affections to overcome in further phases is necessary. In this study, we analyze the student feedbacks and student achievements after one semester of emergence distance learning.
