PS - to clarify the term “public” school:
In the UK, so-called “public” schools were historically the elite privately-funded (boarding) schools. Those were considered to be “public”, because they were not tied to someone’s place of residence.
Of course, in reality they were most decidedly only open to the upper segment of the “public” that actually had the means to afford the tuition.
Since the poster is writing from India, I’m not certain if we are all using the term “Public” School in the same sense!
