This seems like a massively important bit of context which was missing from the article, thanks for telling us this! The article is clickbaity, given that I learned more context from your HN comment than their whole page of text.

Schools have been open for months in many states. And more importantly, most schools have summer vacation now.

Schools have been open for months, atleast in the Delhi region

what is the reason for churn?

Online classes from schools in India didn’t engage kids beyond 2-3 hrs. That left a big time void which were filled by these online coaching classes.

But now with physical schools starting kids will be busy for a good 6-7 hrs after which (and home work, playtime) they will hardly have time for online coaching classes. Parents would soon realize this, if not already, and discontinue subscriptions.

This is why America is doomed internally.. we cant even have a discussion such as this, regarding what kids are busy doing studying.

I mean the entire dialogue around education from a cultural perspective is completely void in the US.

We don't educate, we school.
