<p>Any suggestions about which one will be the best for me on the test?</p>
<p>might want a graphing. Are you in middle school or something</p>
<p>No, I have a TI-89 but last time I checked you can not use it on the test.</p>
<p>there is no need for a graphing calculator, though you are allowed to use TI-83, TI-84, 84+</p>
<p>I would recommend TI-83/83Plus/84/84Plus.</p>
<p>TI-84+ has served me well</p>
<p>I, too, recommend a graphing calculator, if you know how to use one or have time to learn (since you have a TI-89, I'd think you'd be fine). There are lots of graphing calculators on eBay for reasonable prices; a lot of TI-85s are selling for the same price as that Casio.</p>
<p>With the two-line display and everything, that does look really nice for a scientific calculator.</p>
<p>i'd suggest a ti-83. ti-83's are allowed on practically every test you'll have in the future.</p>
