Had to buy a CX for my high schooler. Schools require the CX because it can be used for standardized tests (such as the SAT). Apps, as well as the TI Nspire CX CAS (Computer Algebra System), aren't allowed.
Though the school may not allow it, I think SAT does allow CAS while ACT does not.

I graduated a year ago with a math/stats degree and I got through every class using a $20 TI-30XS multiview. That includes the typical high level math classes (multi-variable calc, Linear algebra, and the highest level probability and statistics courses). I didn't need any form of a graphing calculator once.

The teachers that require it are most likely uneducated high school math teachers. I remember my high school stats and calc teachers making me buy a graphing calc. What a waste of money
I agree that a TI-30XS is sufficient, but much preferred the larger screen for seeing multiple calculation steps at once.

For high school, you could not bring CAS. CX is the most advanced calculator you could use there.

FYI, this model is not allowed in ACT exams.
I think this one is, but the CAS versions are not.

Eh. There is something to having history and scrolling. I used my 89 15 years ago just to check as I went along. Sure, I could put in the full integral or differential, but that was just a bonus to double check.

Like you said, it is mostly used for arithmetic. Bun when you are knee deep in showing your work, you want to be able to scroll up and see where things went wrong if they did.
This.

CX is fine for any test in high school.
