Like everywhere else in India, schools have remained shut since March last year when the country went into lockdown to curb the spread of Covid-19. Affluent private schools and their students switched to online classes seamlessly, but government-run schools have struggled. And their students - often with no laptops or smartphones and patchy access to the internet - have fallen behind.
In Jharkhand, a largely tribal, poor state where Radhika lives, this digital divide is stark. Her family is Dalit (formerly untouchable) and at the bottom of a deeply discriminatory Hindu caste system - as is most of the village. There is no internet in her tiny village in Latehar district. Government or state-owned broadcasters have been running educational shows in some states but that's still inaccessible for many communities.
