How old are you? And, for that matter, how old is the person you're responding to? In 1998, at least up to a TI-81 was allowed on the AP Calculus Exam (possibly higher than that, but you couldn't use anything that was programmable). I have to think it's been a very long time since no calculators at all were allowed for math exams unless you're talking arithmetic exams in elementary school where the entire point is to test how well you've memorized times tables or can perform manual long division.
