<p>"The prepping happened in the classroom."</p>
<p>You related this comment to the SAT II, but what you don't see is that this relates similarly to the SAT I. Again, it's about pedagogy in addition to ability. Reasoning is something that is taught. Also, test-taking is something that great schools teach. I don't mean "teaching to the test" (in either case). I mean general test-taking strategies, which the publics in my area, as well as the non-Catholic Christian-titled schools do <em>not</em> each. For lots of reasons way too boring to go into here, schools up & down my vast state tend to approach "learning" as a gas-station stop: Open brain, fill up with temporary facts, regurgitate said identical facts on a lame objective test, and move on to the next station.</p>
<p>It is not universally practiced in this country. There are some great schools & regions of schools in the MidWest & the East. There are fab privates in the east & west which begin grooming for the SAT I indirectly long before that test's season. By middle school the reasoning process is well established in the students' brains (as well it should be), so whatever the eventual score, it is likely to be reflective of the best that student would have been able to do on this (very left-brained) test. There is further direct teaching to the SAT I within some schools in the east (& not as a supplemental commercial program). </p>
<p>And do these disparities, when known, result in vicious competition to attend such schools -- be they public or private? (Something mammall alluded to.) Yes! And already. And the fewer such schools in whatever region, the more intense the competition. It's beyond the SAT I. It just <em>is</em>.</p>
<p>"Just read a lot and pay attention in math class."</p>
<p>No, not if you have a rotten math teacher -- a series of them -- which is the situation in my state. Maybe 5% of the math teachers in my region are capable of teaching the quantitative <em>reasoning</em> necessary to relate the <em>questions</em> on the SAT I quantitative to the <em>classroom material</em> being taught (& taught poorly). When you have 6-figure-earning careers for mathematicians next door to most of the suburban school districts, good luck finding willing, excellent teachers. They have to be both altruistic & competent to resist that.</p>
<p>Geometry is taught particularly poorly. This is true for most of the students I see. One public school in my area is lucky enough to have an "old school" geometry teacher that actually insists on proofs & teaches from theorems, but most do not, & almost no one teaches logic or teaches logically, which is essential. At my D's otherwise outstanding private, geometry was virtually untaught. Thus, while she aced the verbal, as well as the algebraic reasoning on the SAT I, the subscore on the geometric reasoning for her & all the classmates on her level hovered around 75%. (Many private schools base their core curriculum on "the State's standards." Well, that works when the standards are very high. Check out some states in the Union & you'll find the expectations are not so high.)</p>
<p>For these & other reasons, relying on an SAT I as the most important or winnowing factor for college admissions, is a poor decision. This is why SAT I is and should only be, one factor. It should be looked at in context of the students' other academic indicators. So although my own D & a couple of her classmates did not get perfect SAT I quantitative scores, 2 of them got 800 on the verbal and were offered promotion to AP Calc BC, over the math-type students who finished AB but were <em>not</em> promoted to BC. This is an example of reading everything in context (holistically), and why a data point in itself is meaningless, & it is also why those 2 students were admitted to 4 Ivies.</p>
