<li><p>An mistake done by Collegeboard
-> doubt it. they must have known beforehand</p></li>
<li><p>Collegeboard didn’t have time
-> doubtful. ETS has a LOT of resources and the experimental section existed forever.</p></li>
<li><p>The test was not released therefore it was safe
->it was not publisehd but the answers were to test takers.</p></li>
</ol>
<p>By the way the ESSAY prompt was different but I don’t think anything else was.</p>
<p>i believe they used the same test thinking it was never released by test takers. but unfortunately CCers have never lived up to the statement they rewrite on the test.</p>
