<p>For the AP Calculus Exam (BC), could I use a TI-89 and a TI-84? I've used the TI-84 since middle school, but I like the TI-89's derivative, integral, and solve functions.</p>
<p>So does anyone know if I could use both on the AP exam?</p>
<p>Yes, you may.</p>
<p>But you may want to talk to your school’s AP coordinator in advance so that they know that this is the rule as well.</p>
