<p>Some of the schools that require SAT II tests accept the ACT in lieu of both the SAT I and IIs. All of the reach schools my daughter applied to (including 3 Ivies and U Chicago) were this way. She liked the ACT format better and did much better in it in practice tests and so didn't take the SAT I. Her SAT IIs were lackluster (probably a combination of texts that didn't correspond well to the tests and nerves on test day), so she didn't even bother submitting those scores. Once acceptances came in, her choice came down to Brown versus Chicago.</p>
<p>Then again, there aren't any SAT IIs that relate to her chosen field. So schools weren't going, "Hmmm ... why didn't she take X?"</p>
