IMO early success is not as good as it seems, because often the person may not be able to repeat the same performance due to various factors as time passes and then he or she may get depressed.
When I was 14, I knew VB and C and was doing voluntary beta testing and preparing bug reports all day for many software firms in the security industry. I made a lot of contacts, etc. and a few enemies too (come on, it's the internet

). I got a lot of praise too.
However, my marks were never great. The media, the people, our society, they only care about success in exams, not about people's abilities. I got to meet entire development teams of companies and chat with them, yet, my immediate peers didn't really care about that. My 75% "low marks" in 10th mattered more to them than my success with these "unnecessary activities". I stopped my internet activities and testing later to concentrate on studies, and due to a lack of time.
The thing is that there are many, many kids who do wonders even at age 14 (or even less). Some compete at national level in sports. Some win international swimming tournaments. Some win computer gaming parties. There are countless things I can go on about.
But our media and society cares much more about marks in exams than such things and that is plain wrong!
As time passed and I saw this, I used to feel a little depressed......but now, I am older, I am wiser. I do not care much because my abilities are out there and anyone can see it. And that is the same for all of you -
I always believed that every person is really, really good at something that no exam or test can ever prove.
So, while I must applaud this boy's success at this exam, this is also a time where he should be careful - because if he doesn't continue repeating such success, people will begin thinking badly of him and he can fall into depression.
And remember, there are other kids doing various other things at young ages.....very talented people whose talent is ignored by the country. Remember them too when you read these things!
