<p>I know this has been asked a number of times earlier, is there anyway I can take the Reasoning when I'm registered for the Subject Tests?</p>
<p>You cannot take both SAT I and SAT II during the same sitting. You'll have to choose one and pick a different date for the other.</p>
<p>I'm not sure if you can switch tests when you're already registered for one. My guess would be not.</p>
<p>...switch between SAT I and II, that is.</p>
