Best calculator for aps!

<p>Hey guys,
I'm stuck deciding between these two calculators:
1. TI-89 Titanium
2. TI N Spire CX Cas</p>

<p>Now my main questions are:
1. are both allowed on the sat/ act/ all ap tests?
2. i understand that there are alot less programs available for the nspire so i wont be able to download many apps for the nspire for ap physics/ap calc/ ap chem.
however, is it still worth it to get the nspire?
3. is the nspire easier to learn than the 89? its super hard for me to get the hang of the 89..
4. will the nspire be usefull to me in multivariable and college physics?
5. is notefolio/similar programs available for the nspire?</p>

<p>if anyone else has made a similar decision, please let me know which calculator i should get.
if there is another calculator out there i missed out on, please let me know.
also, please do list the pros and cons for each calculator!</p>

<p>thanks so much!</p>

<p>I’m not familiar enough with the NSpire to answer questions 2-5 but I’m sure that the answer to your first question is partly yes/partly no. The ACT will not allow either calculator. The SAT and AP Exams (and Subject Tests) will allow both. Do note that calculators are only allowed for the Math Subject Tests and for certain science/math AP’s.</p>

<p>From what I’ve heard and my brother’s experienced, hardcore math doesn’t use calculators. Also, I never used any apps for AP chem or AP calc.</p>

<p>yeah but i mean alot of my friends who took ap calc, used the ap calculus apps and ap physics apps from ticalc.org on their 89. but if i get a nspire cx cas, does anyone know how to put those apps into the nspire cx cas?</p>

<p>Both are allowed on any AP where calculators are allowed. I believe both of those are banned on the ACT, but both can be used on any SAT/subject.</p>
