> Calculators are useless on the SAT anyway.

Graphing calculators can be used to quickly solve certain problems, like simultaneous equations or quadratics. They can also be used to plug in multiple-choice answers to see which one is correct, without knowing how to solve a problem the normal way (or not taking the time to, at any rate).

The new adaptive digital SAT complicates things a bit, in that some questions are not multiple choice.

When I took the SATs, it was still the slide rule daze. Graphing calculators didn't appear until many years later.

Fair enough. I'm just pointing out that calculators are not useless on the SAT. Knowing how to use the provided graphing calculator, or having your own and knowing how to use it, is very important if you want a top score.
