Please note that this particular challenge is actually pretty tough! At the end of the test, if you don’t get a score of 100 or more, the automated answer will say, “Your score lies outside the range that the test is currently able to measure”.

Please also note that it’s common to get different scores on IQ tests, even if it’s the same test taken at different times. There are many reasons for this, like how you’re feeling that day — tired, hungry, or in a certain mood.

Of course you can take the practice test as many times as you want. Good luck!
