<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>
