IQ doesnt test intelligence, it tests potential. The absolute ABILITY you COULD have. I was in a advanced schooling system called "Ables" from 1-8 grade (its an acronym i just dont remember what it stands for). To get in, i had to take a series of tests, the SAT which tested actual knowledge, a IQ test which was done over a series of 4 hours with a psychiatric expert, and a few others testing other states of logic, math, and problem solving skills (logic and problem solving kind of go hand in hand). I never received my actual IQ results, I only know to get into the program you were in the +140-145 range (3 students from each school in the region COULD go, but not necessarily always had 3 that met the standards) My good friend until high school was in the program with me and he surpassed most every student, now in 11th grade hes in the standard classes and failing all. The point is, technically hes a "genius" but he is not using pushing himself, and therefore not getting any smarter.
Spark notes: High IQ doesnt mean you are automatically smart.
Ables funding was cut 2-3 years ago.
