QB test is where they measure your movement, concentration and impulsiveness. You have to recognise shapes on a computer and indicate with a clicker when there are two of the same shapes right after each other. It's duration is 20min.

Hey there, I did the QB test today and was in total shocked over my results which showed significant numbers in hyperactivity and attention deficit (I guess that's why I'm using this app, haha). But I wonder if the coffee I drank before could have been the reason for the extreme results. Any thoughts on that?
