<p>So basically my sister is done with all her math classes from college and I've inherited a small collection of graphing calculators.</p>
<p>TI-83 Plus
TI-84 Plus Silver Edition (currently using)
TI-89 Titanium
I also have access to a TI-Nspire CAS with Clickpad, my calculus teacher gave these out to each student to use on the AP test. </p>
<p>I was just wondering which graphing calculator most people use in higher math classes and if I should switch to the TI-89 or Nspire or stay with the 84, which I'm really familiar with. I'm in Calculus BC right now and I want to be able to use the calculator on the AP exams and SAT.</p>
