<p>bro, NO calculator program could be possibly worth 800 bucks no matter what it is, besides, as bman14 said you cant really use your calculator for half the test anyways so u might as well be studying, not to mention that your calculator could already be a good help on calc tests w/o any program (u could integrate, diffrentiate, implictly diffrenciate, download the Calclus flaash app from tii website for more.etc…)</p>
