On the PSAT/SAT…. my twins took the old version of the SAT at 12yo and did quite well (if you ignore the writing score) with no prep whatsoever other than a single dry run with the sample exam provided by College Board. They will graduate h.s. in 2018 so are on track for the new version. I was thinking that the changes in the test could work in their favor because the test-prep machinery for the new version will take some time getting up to maximal performance. By 2018 maybe colleges won't take the old version any way, so perhaps this is a moot question, but would like opinions on this strategy?

Barring unforeseen disaster, I think at least one of the twins (they are both good test takers, but one has a clear edge) has a good shot at NMSF.
