<p>Assuming you mean the ti-84, don’t bother with that, instead search up the ti-nspire (go to this thread <a href=“http://talk.collegeconfidential.com/sat-subject-tests-preparation/1143919-what-sat-physics-math-level-2-books-should-i-get-sat-subject-test-book-reviews.html[/url]”>http://talk.collegeconfidential.com/sat-subject-tests-preparation/1143919-what-sat-physics-math-level-2-books-should-i-get-sat-subject-test-book-reviews.html</a> there’s a link to it).
Nspire is soooooo much better than the 84, i have used both. And you can get used to it in about 1 month (or even less), so you’ll be fine.</p>
