I bet schools in India pressure children to be challenged and excel while schools in the USA don't pressure children to be challenged or excel and instead focus on how good the children feel after a day at school.
Remember schools are not about learning, or competition between students..its where EVERYone, regardless of their ability or the amount of effort they put in, excels. At the end of the day everyone is equal, and happy.
I have maintained that if schools here set a really high bar, our students will excel. Imagine if American kids had to do 2-3 hours of math and science homework a night.
