How keen is your memory and perception???
This is a good memory test for those who wonder if their memory is getting better or worse.
There are at least 5 differences between the two picture you will see.
First click on the "Superman #1" button and study it. Then click on the "Superman #2" button and see if you can spot the differences without looking back at the first picture.
If you score 1 you are below average intelligence, 2-3 average, 4 above average.
If you find 5 or more you are in the top 5 percent of recollective memory intelligence.
Don't cheat! You can study the first picture for as long as you like.
How well did you do on the test?
