Introduction: The Coronavirus-19 pandemic has thrown the world into survival trauma. The negative effects of anxiety on academic performance had been shown in many studies. The pandemic of Coronavirus-19 increases not only the symptoms associated with grief but also mental disorders such as post-traumatic stress, depression and anxiety disorder. Aim and Objective: This paper examined the anxiety about Coronavirus-19 among university students who recently experienced face-to-face and non-face-to-face classes, to suggest a better class type for high-quality academic performance with less fear. The survey was conducted on 94 nursing college students in J. City, South Korea, from June 27 to June 30, 2020. The State Anxiety Inventory (Spielberger, 1975) was employed online. Result: The findings showed that there was a significant difference (t=12.113, p=.000) in anxiety between face-to-face (53.05__ampersandsignplusmn;9.41/80) and non-face-to-face class groups (37.46__ampersandsignplusmn;7.63/80). That of face-to-face was 1.41 times higher than that of non-face-to-face. There were significant differences with regards to class preference (t=12.113, p=.000) and gender (t=12.113, p=.000) only in the face-to-face but not in the non-face-to-face group. The non-face-to-face preferred group had scored 1.22 times higher than the other group and females had scored 1.19 times higher than the males. These results were highly significant (t=13.958, p=.000) in the high anxiety than low anxiety group in both classes. The score above 40 in the high anxiety group (54.66__ampersandsignplusmn;7.215) of the face-to-face was 1.86 times higher than in the low group (29.33__ampersandsignplusmn;4.131). 93.62% belonged to the high anxiety group in the face-to-face group. Factors affecting anxiety were class preference (__ampersandsignbeta;=-.546, p=.001) and gender (__ampersandsignbeta;=.244, p=.004) in the face-to-face group. The explanatory power of these variables was 74.7%. Conclusion: It is suggested that students are more worried about Coronavirus-19 spread within the classroom than about difficulties from the non-face-to-face class. In this study, the non-face-to-face class is recommended, especially, for non-face-to-face class preferred and female students, for better quality academic achievement in universities, without worry during Coronavirus-19 epidemic.
