I was reading at a college level by 5th. I never took a test in 4th grade for it. I just remember getting back this special reading test that I took and it said PHS (Past High School) on it. I wish our school would give us an official IQ test. I've always been curious as to what mine was but I've never taken the time to take one myself... Btw, the answer, 4. The problem was simple. I've always been good in math. Next year, in 10th grade, I plan on taking calculus. I'm taking algebra 2 right now and my teacher said that, if I keep things going the way they are, that I can skip pre-cal and just go on to calculus next year. The average student at my school doesn't even take calculus. They take pre-cal in 12th grade and then go to college.
