1 -IQ alone is almost useless to any practical purposes, let it be a genius, get money, or have a brilliant career in wherever field you like. There are things more important than that: self-discipline, creativity, how well you perceive the reality, how well can you structure you knowledge, personal relationships, etc.
2 - There are several metrics to measure IQ, no hint what this site uses.
3 - Some questions involve more previous study in math than intelligence, for example, one about the Fibonacci series
4 - Some questions are far easier for English native speakers
That being said:

EDIT: seems I made all right when I review the questions, does time counts too?
