This test intends to measure your IQ.

The maximum IQ is 170.

In each item you can see two matrices.

These two matrices were logically organised but someone has exchanged two squares...

You must indicate which pair of squares (one square a matrice) was permuted.

LET'S SEE THREE EXAMPLES :

Solution = 76 (see below the way of answering)

because the seventh square in the left matrice should be exchanged with the sixth square of the right matrice to form two coherent matrices.

This picture shows how to indicate the squares to be exchanged.

Solution = 63

because the sixth square in the left matrice should be exchanged with the third square of the right matrice to form two coherent matrices.

Solution = 84

because the eigth square in the left matrice should be exchanged with the fourth square of the right matrice to form two coherent matrices.
