Maybe it isn't about a harder test. Let's say that current perfect scores get you a group at a top school with IQs of 135+. Maybe it is 140+. With a different test, do you get 150+. But do you get a group that you want? Do they have the social skills to have a good mix, good clubs? There are factors that you want to have a certain type of school whether you are Harvard or Penn State. Harvard doesn't want a whole school that could pursue graduate work in Physics. They want fencing teams and rowing and a football team to play Yale. So for those of you wishing for a harder test, what does that mean to the student body, the college experience if you don't take into account all the other things. Because how much does it change if your roommate has an IQ of 175 in math, but 125 in ELA or 145 overall? I can see MIT wanting the 175 in math but Ivy's? Do you really want your kid going to a school where they just sit and have deep discussions about theories with other students?
