All these things that I have done

No, no. They ask you what your salary is and then calculate your IQ. The combination of the two is your quotient. So a quotient of 0 means you're being paid about enough for your IQ, positive says you should be paid more and negative less. I don't think the IQ test is very good though, as you're not timed (although it does tell you how long the control group had to complete it so you could time yourself).
