How to choose
- Check the rules first. Every model here is widely approved, but policies change, so confirm your class or test allows it.
- Graphing vs scientific. Get a graphing model only if your course actually needs graphs; otherwise a scientific calculator is lighter and cheaper.
- Stick with one. The best calculator is the one you know well, so practice on the same model you’ll use on test day.
- Screen and battery. Color is easier to read; a rechargeable battery means no dead AAAs mid-exam.
Any of these will do the job for most students. If you want a single safe pick, the TI-84 Plus CE is the dependable all-rounder, and the Casio fx-9750GIII is the one to grab when money is tight. Whatever you choose, get comfortable with it before it counts.
