Is it for you

Buy it if

  • You need a graphing calculator for one course and would rather not spend TI money
  • You want a backup calculator in the bag for test day
  • You'd rather swap AAA batteries than keep track of a charger

Skip it if

  • Your teacher will demonstrate every step on a TI-84 and you'll want the menus to match
  • You need a color screen to tell overlapping graphs apart

The fx-9750GIII does the work a high school course asks for: graphing, tables, regressions, statistics, and matrices. It does it on a low-resolution screen that shows its age next to a color TI. Owners call the icon-based menu fast once learned and confusing for the first week.

Used units cost little because the new price is already low, so condition matters more than model year. Check the battery compartment for leaked-AAA corrosion on the contacts. It’s the one real failure on a calculator that otherwise has nothing to break.

Its predecessor, the fx-9750GII, looks similar and doesn’t run Python. “GIII” is printed on the face.
