The language used in the letter seems to be written by an exceptionally gifted 8th grader. I'm from the UK, so I'm not sure what the standards are like in the US, but I would be surprised if many 14 year olds in the UK could write a letter of that quality - it makes me a little suspicious as to whether the letter is in fact genuine. Either way, pushy parents are creating unreasonable expectations and anxiety for their children. Kids in large developing countries seem to get the worst of it, where competition and expectations are both off the charts.
