<p>Yup, you can take up to 3. Although every test is not offered every sitting. The most common ones are, but it used to be that a few (eg, world history) weren’t offered every single time. My kids both did 2 at a time (they didn’t have time to study for 3). But some of their friends did 3 in a sitting. You can’t take the regular SAT on that same day, though (just in case you were considering another sitting for that).</p>
