<p>I am planning to take the SAT II math 2c in October...
I haven;t started learning it yet...
At this moment I own 15 practive tests of meylani and the barrons book.</p>
<p>I am decent at math, but I wonder if it's possible to get 700+ with a Ti-84 if you are not a math genius... Or is it recommend in my situation to get a ti-89??</p>
<p>Have you taken a pre-calculus class (and done well in it)? If so, then you should be in decent shape for the test. The test is not "easy" per se, but if you put in the time and practice with the books you have, then you should do well. As for the 89, it's useful for the IIC, but I wouldn't go out and buy one just for this test. If you're going to be taking Calculus this year (or soon), then the 89 might be a good investment. That said, it's quite possible to do very well on the IIC with only a 83 (or 83+ or 84 - calculators without CAS). Take a test or two and see how you do with your 84 before you make any purchasing decisions</p>
<p>The TI-89, while more powerful then the 83 series, has an arcane OS that can make inputting simple functions time consuming. You shouldn't need anything higher then the 83 series at all. I used a TI-30 and got a 790, but then Im good at math. An 83/84 is an advantage, but anything higher is unnecessary.</p>
<p>Graphing calculator probably stopped me from answering all the questions. With functions such as graphing, it made me want to check my answers a lot, which was time consuming. One good thing about graphing calculators is the large display when doing simple arithmetic with multiple steps. It helps you keep track of what you're doing.</p>
<p>I agree that graphing calculators help. But don't check your answers until you've done all the problems you can. That's just logic.</p>
<p>Any graphing calculator will do. You just need the basic scientific calculator functions, and the graphing part helps a lot. The most important thing is that you are familiar with your calculator.</p>
