<p>No, TI-89's are not allowed. :(

<p>Nope, it's disheartening; I had to learn how to use the TI83 again.</p>
<p>TI 89s (to my dismay on my first ACT) are not allowed on the ACT. Foolish me had forgotten to check the banned calculator list...</p>
<p>Second time around, thank goodness (I suppose) my math teacher forced me to learn how to use a TI 83 even though I owned a TI 89, so I'm not too terribly alienated with the different calculator model.</p>
