(a–d): a) A greater proportion of students from the higher income groups had access to a Wi-Fi router and dedicated room at home to attend online classes. Also, proficiency in the usage of the internet and computers was better in the higher income groups (p < 0.0001). b) A similar pattern of responses was seen with students from cities having better availability of Wi-Fi router and dedicated room at home and better proficiency in computer and internet usage compared to those in towns and villages. c) Network issues were more frequently encountered when students used mobile data rather than Wi-Fi router for internet connection (χ²s > 3.86, df = 1, p's < 0.049) d) Network issues were less when the students used personal computer rather than mobile phones during the classes (χ²s > 9.23, df = 3, p's < 0.026).
