<p>AP Stats is in 3 days.. And I was wondering if there were any programs out there for the TI-89 / TI-84 that would really help with the test?</p>
<p>Well the only stuff you need is already on both calcs. You just need to know when to use them.</p>
<p>There is a program called Catalog Help which tells you exactly what you need to press (lists the parameters) to do everything on the ti-83. Check the web, but in general everything you need should already be on the ti-83.</p>
<p>^ Okay thanks~ I mainly use a TI-89 though.. ;/</p>
