The results indicated that a COVID-19 pandemic has had a variety of impacts on the education sector, including curricular delays; group and individual absences; and students forgetting previous lessons. Furthermore, online teaching has not been successful at all which has caused teachers to be unable to conduct their study plans. In light of the results, some recommendations were presented.
