The break-down of the Covid-19 pandemic has changed the situation of the educational sector from traditional i.e.; face-to-face learning to online learning. The present study aims to know the behaviour of students towards online learning and the problem faced by them. The research is descriptive. The data is been collected through an online survey method from 76 undergraduate students. A convenient sampling is been used to collect the data. The data is been collected with the help of a questionnaire and interview. The data is been analysed using MS-Excel. It was revealed that 77.6% of students consider online learning an effective and better choice of learning. Moreover, students feel that online learning is better than going to college. This study has also given insight into the problems or barriers faced by students during online learning. The major problem faced by students while online learning is internet connectivity is poorly followed by eye strain, increase stress, and homework. A suggestive measure was recommended for the improvement of the problem faced by the student. The laziness of students is more in online learning. Hopefully, the results of this study will help in improving students' behaviour towards online learning during the Covid-19 pandemic. Furthermore, dimensions can be studied on this topic.
