Probably that you're getting older. Is the test calibrated for age? After I got a really nice score on my GREs, I never officially took another IQ test. Why mess with success? <^..^>
Yeah all of the tests I've taken are timed AND age is calculated into the test results.
But I can feel my mental faculties slowing.
I think it is due to the meds I need to take to function. Rx pain meds for severe arthritis in my knees and ankles.
