I think it is a TI-30, or something with similar functionality that looks almost the same. I lost mine when I moved.

Besides the issued calculator, are we allowed to bring our own from home? Say a TI-84 for instance, and can we use it in class?

i forgot where it was but i remember reading something about calculators specifically at the academy and the rules ... it was something important but i'll post back as soon as i find it. i think it might be in the appointee instructions pdf

Some 4* classes will require use of the honorlator but most advanced classes don't care. I've been using my TI-84 as my primary calculator for the last three years.

I almost never used my honorlator. I brought a TI-89 from home and used it for most classes and tests. It is really just the basic core classes that require the honorlator (like chem 100/200, physics 110/210 (not honors), maybe calculus, but I'm not sure I think they use calc tool instead). In all my math and physics majors courses we could use whatever calculator we wanted.

is there any point in getting the 89 for later taken advanced classes if i already have an 84? only got the 84 last year because that's the one the teacher guaranteed they'd be able to show us how to use. a couple random kids with 89s were sorta on their own and the teacher had to look up how to do some stuff.

No need to get one beforehand. If you get here and decide you need one, go for it. I have always just used the 84 for basic math functions since it's much easier to make an error on the honorlator. For any advanced math, Matlab and Mathematica are pretty standard tools.

As a physics major, I can tell you the 89 was awesome to have because of the frequency with which we do integrals (they become as fundamental as algebra really) and I always preferred the user interface on the 89, but I was the exception and you by no means need one, it was just nice to have. I also use it a lot at work now, so it was a worthwhile investment for me.

The honorlator the freshmen are using this year is the TI30XIIS. Math 141, or Calc I, uses this calculator, in conjuction with a graphing program on your laptop called CalcTool, for the graded reviews. Our teacher lets us use a TI-84/86/89 for in class work.
