IQ test:  
by  Zervos

When you apply for admission to a High-IQ society you will be asked to sit for a  proctored test.
I have devised some examples similar to the questions you are likely to be asked.  

How clever are you? Be honest with yourself. If you can correctly answer EVERY one of my questions in the time allowed you have a good chance of being accepted into one of the High-IQ societies given in the list mentioned below. Otherwise take your time, have fun and enjoy answering the questions with your family and friends.

Time allowed 60 minutes:
Do NOT use pencil and paper,
(except where I have indicated otherwise) .
I have made the questions easy.  No special skill or knowledge is required, just your wits and logic.

The answers to IQ test questions are not normally revealed but I have received many requests to do so, and as these are examples only, I have relented.

Contact your preferred society directly if you want to sit for their proctored test. The acceptance scores vary. For example the popular MENSA society accepts only applicants who score in the 98th  percentile* level or better. A list of international High-IQ societies and their statistics can be  found in the table HERE  ---  SZ. 
A Percentile is not a score. If you score in the 98 th percentile it means that less than 2% of the population has equalled or exceeded your score. The MEGA society's requirement is at the
99 th percentile level or better.
