<p>My son took the ACT his sophomore year and got a 36; he figured he was done with these tests. Yet his school required him to take the PSAT the following October; he forgot about it and showed up without prepping or a calculator and still got the 240. Later he was told that he had to re-take the ACT as a junior to be allowed to graduate (state law), so he re-took the ACT and got another 36, again without prepping or a calculator. He did not bother to take the SAT.</p>
<p>If one takes the SAT first in an ACT-required state, it’s quite possible to end up with two perfect scores. Silverturtle got them and there have been others on CC. I would think that the vast majority of those who got a perfect score in one test could get to do so again on the other; it’s mostly a matter of being forced into a situation of needing to take both tests, either for graduation requirements or to maximize potential merit scholarships.</p>
