<p>What are some really good apps (free) to have on my TI-84 Plus for the SAT/ACT?</p>
<p>I cannot find SAT_OS.</p>
<p>Does anyone know any others?</p>
<p>Any one that can solve equations?</p>
<p>Anything would help!</p>
<p>There’s a thread on here somewhere, search for it.</p>
<p>They’re really not that helpful if you think about it though.</p>
