<p>“It may be advantageous for a student to take both in junior year, since some students do better on one than the other. That also give a chance to retake the higher one after additional preparation in senior year if desired.”</p>
<p>While there is some east/west regional bias between the two tests, this is the optimal thing to do. Take both tests untutored spring of junior HS year. Figure out which test suits you better. Prep for just that one test over the summer and take it for real in Aug/Sept of senior HS year. The important thing is to post the best score (meaning highest percentile) possible Worked like a charm for all my kids.</p>
