<p>I've decided I only want to take SAT II Bio E, rather than Math II again. Can I not take it on the actual day without being penalized? </p>
<p>And can you replace, say, Math II with Lit on the day of the test? </p>
<p>Yes - my kids learned this and we were surprised. You can change your mind the day of, as long as you tell them which tests you want when you arrive that morning. You can also decide in what order you want to take them that day.</p>
