This is the result from the Mensa admission test. 
The result is 36 right of 36 questions which gives an IQ of at least 135 which corresponds to 1% of the population and gives membership to Mensa.
However, about 90% right is enough to get membership to Mensa. Which corresponds to 2% of the population.

You find that I was very old when I took the test. But to my surprise I solved all the problems at half the time. So I think you will manage it too.
