Is it for you
Buy it if
- You are headed into calculus or engineering and want document-style work with graphs, tables, and notes linked together
- You are sitting the ACT and want the most capable calculator it permits
- Python is on the syllabus
Skip it if
- Your teacher teaches on a TI-84, since the menus share almost nothing
- The seller can't confirm whether it's the CX II or the CX II CAS
There are two calculators with nearly the same name. The CX II and the CX II CAS look almost identical, and only the CAS has symbolic algebra. That model is on the ACT’s prohibited list. The word “CAS” is printed above the screen. Check for it in the photo, not just the title.
The Nspire organizes work into documents with pages, closer to a notebook than to a calculator’s home screen. Students who settle into it rarely go back. Students whose teacher works on a TI-84 spend the year translating.
Press-to-Test leaves a blinking LED and locks out documents until it’s cleared from another Nspire or a computer. Ask the seller to reset the unit before shipping.
