I discovered in grade 12 that IQ tests were graded taking time to complete the test into consideration.
One day after lunch, I realized a bathroom break before returning to class would have been a good idea. No problem, I would just get permission to leave the room for a few minutes.
Wrong. In walked the guidance counsellor and announced we were taking IQ tests. I asked for permission to leave but was denied. I would not be allowed to leave the room until I completed the test. The test was expected to take an hour. It's funny how that seems to increase the need.
I have benefited from reading quickly and knew I would have only a short time to avoid catastrophe.
I hit that test and went trough the entire thing in less than a half hour, passed it in and asked permission to leave. Granted!
A month later I was called to the counsellor's office and had my score revealed to me. The time factor boosted the score by about 30 points.
I didn't tell him why I had ripped through it so fast. It would have seemed dumb.
