<p>Right??</p>
<p>i'm taking a retake SAT II math in october.
i'm also taking ap statistics and BC next year.
took calculus this year (i should have gotten it, but i didnt for some reason)</p>
<p>No, you won't need it. You may not even be able to use a calculator at all. You definately don't need it for the IIC. You definately don't need it for Stats or BC Calc either. An 83+ is just as good. It can evaluate integrals which is all you basically need it for in BC Calc.</p>
<p>The TI89 is AMAZING for standardized tests. BUT:
calc bc: your teacher probably will not allow you to use it (or any other calculator)
statistics: ti89 is abysmal here; an 83+ is the preferred option, in my opinion
multivar/other college calculus: professor most likely won't let u use any calculators</p>
<p>if u do decide to get it, make sure u learn how to use it, because your teachers sure won't tell you</p>
<p>actually i heard in college u don't get to use calcs even for calc!</p>
<p>Lies.</p>
<p>TI-89 is just the same for stats.
TI-89 is at least more useful on the BC AP exam than the TI-83, which is virtually useless except for integration with limits and explicit differentiation with a specified point.</p>
<p>Get it. It will be your best friend, if you master it.</p>
<p>I got through engineering at Rice without a TI-89. I used my 83 the whole time, and it was just fine. If you've already got an 83, I wouldn't burn money on a new calculator, especially if you won't be familiar with it by test day.</p>
<p>I have just gone through an entire year of AP Stats with my TI 89 and as long as you have the correct program, it is equal to if not better than the 83/84.</p>
<p>well the 89 is superior the 83 in terms of power, bells and wistles. The problem with stats it the 89 somtimes takes longer to do simple problems due to all the menus. I use both an 83+ and a 89 Titanium. I alter it up depending on the problem. I think I'm about the only person in the testing rooms that use 2 at a time on tests. lol</p>
<p>I, personally, find the menus in the 89 intuitive. But I will admit that the 83 is better at confidence intervals in particular (since it gives more significant figures in the output).</p>
<p>Regardless of whether or not you decide to buy the TI-89, DO NOT take a calculator that you aren't completely, 100% comfortable with, into a standardized testing situation. Unfamiliar room, unfamiliar test questions, unfamiliar setting... Last thing you want is an unfamiliar calculator. That little hunk of plastic and silicon is your only familiar friend in there.</p>
<p>I got an 89 this year... It has a heck of a learning curve if you're used to the 83. I still use the 83 on tests because I'm a lot more comfortable with it.</p>
<p>Is the TI-89 allowed on the SAT Math IIC? What about the ACT?</p>
<p>The TI-89 is allowed on the IIC but not on the ACT. You won't need it anyway, guys. I would recommend an 83+, 84, or whatever the equivalent is that's out now. The 89 isn't necessary. If you just want it and can afford it, go for it, but you don't need it.</p>
<p>Edit: And for the BC exam all your calculator really needs to be able to do is graph and find intersections and zeroes as well as graph definite integrals. That's it.</p>
<p>The TI-89 is godly - get it. Period.</p>
<p>You don't need it. Most people I know who got an 800 on the IIC did it with a normal, non-graphing, scientific calculator, as did I.</p>
<p>I got an 800 with an 89. Buy it. There is no reason NOT to have a better calculator, if you can spend the money.</p>
<p>I will say this: if you have any graphing calculator already, don't get the 89. If you don't have any graphing calculator already get an 83+. The 89 is overkill and you can't use it on the ACT so if you are planning to take that be aware you won't be able to use it.</p>
<p>If you can master the TI-89, it will be your best friend on standardized tests. It minimizes errors (by showing you your input how you'd write it) and can solve a number of problems you would have to do mostly by hand with an 83+. The 89 Titanium, more than anything else, allows you to do math much FASTER, which is critical on standardized tests (assuming, of course, that you're familiar with it).</p>
