<p>Hello, I am taking AP Calc, Stat, and Chemistry this May. I realized that for all these exams I will need a calculator..</p>
<p>For AP Calc, I am aware that you are allowed to bring in two graphing calculators and use them interchangeably.</p>
<p>Is this the case with AP Stat and Chemistry? I would like to bring with me TI-84 and TI-89 as I am more comfortable with TI-84 but know how to use TI-89 in areas that the TI-84 are weak..</p>
<p>If I am allowed to bring in 2 calculators, would I be able to use them interchangeably?</p>
<p>Thanks in advance.</p>
