<p>Nightingale - According to my D the ACT has a different "feel" to it than the SAT. She preferred the ACT (and did a little better on it than on the SAT), but it took two attempts to achieve her good score. In her case it was the science portion that caused the most trouble. It was her strongest subject, and on the first attempt her worst subscore. Apparently this section contains quite a bit of graph interpretation. She polished those skills and did fine on the second attempt. I don't know what your ACT strategy is, but you may want to consider our D's experience.</p>
