<p>Hi!</p>
<p>I need good calculator for SAT Physics and Maths level 2. I will also use it during my education in college on tests etc. What should I get? I consider:</p>
<p>TI Nspire CX (there is a problem with this one because I can't find a shop which ships to Europe (Poland) and from ebay.com it will cost me about 200$)</p>
<p>TI Nspire (I can purchase easily from amazon.com for about 160$)</p>
<p>TI 89 Titanum (I'm afraid that it's too old calculator but has great opinions).</p>
<p>What would you recommend me considering prices I've written? Would I lose much if I take Nspire rather than Nspire CX?</p>
<p>And should I take CAS version? Is it allowed during college and on exams?</p>
<p>The SAT Physics Subject Test doesn’t allow calculators.</p>
<p>The Math II test allows calculators with CAS. As for college, the calculator policies of each professor vary: some allow no calculators while others allow laptop computers during exams.</p>
<p>The NSpire CX isn’t much different from the NSpire; the main difference is the color screen on the CX, which isn’t critical for a good calculator. Both the NSpire and the 89 are great calculators. The 89 certainly isn’t too old and has a built-in CAS. The NSpire comes in non-CAS and CAS versions. </p>
<p>Ultimately, I’d recommend the 89 (which I use with my TI-84+ SE) because I’ve heard that the NSpire’s interface is quite hard to pick up.</p>
<p>Like the above person stated, buy a TI 89.
I used that and supplemented it with a TI 84. The NSpire is a nice calculator but it takes a while to get used to. The 84 and 89 can be picked up and used with relative ease.</p>
<p>Also, the only SAT Subject tests that allow for calculators are the Math subject tests.</p>
<p>Hm, are you sure? Nspire has got much more RAM i larger screen, I had been thinking it’s better the TI 89…</p>
<p>And if TI 89, should I take Titanum version?</p>
<p>NSpire has (arguably) better technical specs, but it’s user interface is maddeningly complicated. And yes, get the TI-89 Titanium. Non-titanium also has a CAS, but I believe the Titanium has more RAM, runs faster, etc.</p>
<p>I’ve found good offer for TI Nspire CX CAS and I think I will get it. TI 89 Titanum’s lack of natural input will annoy me, so I would prefer CX. But thanks for advice!</p>
<p>I got an 800 with the TI-84 (I’m also pretty sure I had a raw of 50/50)</p>
<p>I would NOT use the 89.</p>
<p>Honestly, it has 29304820348 times more functions than you really need and it’s difficult to navigate through it for the first time.</p>
<p>Stick simply to an 84 Plus Silver from Costco.</p>
