It'd be pretty tough to use it on the SAT if you take most of the allotted time trying to type out a function.

While you're right about how long it takes to type a function on a calculator like this, this calculator is a huge step up from the TIs kids use on the SAT right now.

That's valid.

You can use it just like a TI-84, its just that it uses Python (which programming curriculums in k-12 are increasingly using) instead of TI-Basic.
