My son took it in 7th grader for fun. He loves taking standardized tests. He did really well on it and qualified for both math and verbal with Duke. They invited him to retake it 2 months later to compare his score with the old and new SAT and got basically the exact same score.
He took last summer a 5-week high school Geometry class last summer at the community college. He did really well in it and the teacher really encouraged him to skip out of Integrated Math 1 for 8th grade, which is what the accelerated 8th graders take.
Our school finally allowed him to do that, really because they were super impressed by his Duke TIP medal and math SAT scores! Although that wasn't why he took it in the first place.
He has a solid A in Integrated Math 2 as an 8th grader. He said he's very happy he skipped ahead
