JustOne, it is absolutely NOT an IQ test and can be studied for. I will admit I did not study as hard as I could but my score from my the first time I took a practice ACT to my one and only real test was 6 points better on the composit, 4 points better on R, 10 points better in English and 6 points better in math. Plus it is very arbitrary, I know at least two people who went up 130 and 150 points to perfect scores based purely on a better curve. One took it 3 times and went up around 250 points or more from his first to his last test. However, it seems the English sections are easier to study for, the math is harder to master if you are not a math person, a boy in my class just never got it even though he is an amazing writer and really bright. One of my friends used to go to a GT school so knew his IQ but is a slacker. His IQ to get into the school was above 97%, his SAT score was not and he took it a bunch of times, just never did much to prepare. The SAT 2 Math 2 can be completely taught, it is about letting the calculator do the work for you and then using very simple math to answer the questions. Finally percentile wise some people do significantly better or worse on the graduate entrance exams. Does that mean you got smarter/stupider while in college. I doubt it
