Basic scientific calculator or a full feature graphic calculator? At a glance, I think I would have been able to prepare just fine for that test as a high school senior with a scientific calculator (means it has +-/*, and log, sqrt sin cos etc.), but it would have been a breeze with a TI-89 (which symbolically solves equations and simplifies expressions). If graphing calculators are allowed that would give a very big advantage to the rich or anyone that knows what a big advantage such a calculator gives.
