Is 133 a good IQ score for a 16 year old?

Answer 1

133 is a good score for anybody. But IQ only says what you COULD do, not what you WILL do.

In the Dilbert comic strip by Scott Adams, Dilbert's garbage collector is the president of the local MENSA chapter, the club for high-IQ people. Dilbert asks, "If you're so smart, why are you a garbage collector?" The garbageman replies "High IQ has fewer practical applications than most people realize!"

So whether your IQ is 100, or 120, or 150, you won't be either happy or successful unless you choose a path in life, and a career, that will allow you to do something worthwhile in your life.
