Actually, you can't use the Ti-89 on the SAT, how do I know this, because I couldn't use my
freakin Ti-89!! Same with ACT, damn bastards.
Not sure about AP Calc test though, but if you really can use it, it probably won't help much
anyway because the problems are less calculation oriented, and more logic oriented. But
it is a great learning tool in my opinion. I've figured out so many problems because it just
doing it for me, I could see where exactly I went wrong... Good stuff...
