Perhaps you get those stares because you missed '14.'

Get the 89 and then give it a casemod so it looks like a inferior version. Then you can take it into exams

According to my friend, swapping the cases is really easy. The 89 almost exactly matches the 83+ and the 89 titanium almost exactly matches the 84+. So just get an 89 (+/- titanium) and the corresponding lesser calculator with a busted screen or something, so its cheap. And as my friend pointed out, its not likely the people handing out standardized tests are going to know the difference between the GUIs, or they wouldn't be handing out the tests.

What about the new TI Inspire? Is it any good?

How small are the guts of a graphing calculator compared to a normal one? Would it be possible to shove one in a normal calculator case, less batteries and some functions, and with a bigger screen hole?

Wow. That wouldn't work at all.
