The study intends to present the key challenges in attending the online classes faced by the students. Challenges have been categorized by different aspects. In conducting the study primary data have been collected by using a well-tailored online questionnaire. Total 508 responded to the online survey where snowball sampling technique was adopted. SPSS software and simple cross-tabulation were used to analyze the collected data. The study found that although highest percentage of students are attending the online class from metropolitan city or divisional city, 30.7% are attending from village area which is a dominating portion of the students. 68.9% respondents are using mobile data which is not cost effective for them. The study also resulted that network and facility related challenges, student-teacher interaction related challenges and personal & socio-psychological challenges are the prioritized challenges complained by the students. Considering the results the study recommended some suggestions that might help for the policymakers to eliminate the challenges of online classes in the future. Regulatory bodies like UGC, government, individual universities and other concerned authorities have many roles to play.
