unfortunate effect of TI's graphing calculator monopoly, but with Desmos gaining traction, it won’t last much longer[/quote]

[b]Desmos only works if connected to internet, a non starter for secure exams[/b]. The alternative is fenced off Desmos that require a technological solution, not easily implemented.

[b]Desmos is great for graphing, but sucks for very basic defining, manipulating and programming variables and functions[/b]. That’s critical for high level problem solving, and success at the AP exams.

Graphing calculators won’t go away soon in the educational market. For speed during an exam a physical button calculator is much faster, I’d rather have that instead of clicking through menus.[/quote]
It seems you're unaware that all SAT exams across the U.S. are now digital, and the same goes for AP exams via Bluebook—both of which require a stable internet connection. No internet, no exam. Desmos doesn’t need anything more than that same connection.

A basic Desmos tutorial would show you how to define variables and use a wide range of custom programming functions that the TI calculators simply can't compete with. TI is built on 30-year-old tech, while Desmos is a modern, cloud-based platform that's constantly evolving—there’s really no comparison.

It's a slow death but TI calcs will phase out of schools. But you can save yours and cherish it.

I would caution against relying on Desmos only. My son took MAP that has a built in Desmos calculator for some time, but he didn’t see the menu button during the test. Handheld calculators build more familiarity because they’ve been used for years on homework’s, quizzes, tests.

My kid has Desmos on his iPad, he’ll mostly use this first, graphing, short calculations, for taking screenshots it is very convenient. For more involving calculations he’ll use TI-Nspire. Faster data input, which in Desmos kind of sucks, like any virtual keyboard app. Try doing an expected value from a table in Desmos and you’ll end up pulling your hair. Much easier on TI spreadsheets.
