All of the exams listed are either already offered in a computerized format or in a transition phase, with the PSAT, SAT, APs, and ACT all already offering Desmos in their testing apps.
I love handheld calculators, but, especially in a time-sensitive environment, it's hard to beat a large screen and full keyboard.
Why are they still able to sell what is effectively a 30 year old computer for as much or more today than when it came out? Because they managed to get the family informally standardized as "The calculator every teacher in America understands well enough to manage students who use it. Therefore pretty much everything else that could be as or more advanced is effect banned."
It was an amazing piece of kit when it first came out. No doubt you could make something 100x better and 10x cheaper today if someone really tried. But, they would fail commercially because you can't design-in 30 years of legacy in the US school system.
tests like SAT, ACT, and some AP exams are using Desmos, yes
however:
- this means you have to fiddle with a popover window and can't always see the full problem (especially when the reference sheet is also online)
- you have less muscle memory and often take longer
- harder to multitask (you use paper anyways, and the paper to calculator friction is lower than the paper to trackpad friction
- trackpads on school computers are usually worse, which compounds the problem
- some specific functions just don't exist
essentially using Desmos is like using a physical mouse/trackpad, while using your calculator is like using VIM motions and keyboard shortcuts with a concave split keyboard. it's technically more intuitive and can help in certain scenarios, but it's useful to have both.
this sounds trivial, but it's not, especially on tests where you have about or less than a minute per question
ideally you have both a handheld calculator and Desmos though
For a lot of people it introduced them to TI-Basic which was quite capable, and for others you could get into Assembly which allowed for more powerful applications. There were 2 parts of the memory, BASIC programs were in regular memory that could be easily erased, and another part which was Flash Apps.
I later upgraded to the 89 which had a better CPU, screen resolution and processing power and it was phenomenal in helping me understand every single math class, including EE/EECS. It made me sad to see them banned in exams, because having a 83+/89/any calculator was in no way helpful in any of the exams I took, but it was more of a "control the students" thing in college. The Math department determined that because they couldn't prove that people were not using the internet/portable PC's in their calculators, that they could not guarantee the fairness of it all.
Weird argument to make knowing that a 20 year old student was engineering a full internet capable PC into a calculator at the time would have been the envy of the world (and every engineering program).
This all depends on the quality of education and not simply handing out problems that require rote memorization of the methods to solve an equation and instead derive or figure out the equation yourself after understanding the problem after which you're free to use the calculator to "plug and chug".
15 year old me in math class programming my loaned TI-82: CHALLENGE ACCEPTED!
Oh no.
…LLM-isms are like nails on chalkboard I swear. Instant turn off the moment I read them.
Even if they’re maybe not lol, doesn’t matter my visceral reaction is negative.
...which perhaps says a lot about the corpora that the models are trained on.
> The keypad layout removes clutter and makes commands and shortcuts easier to see, so you can work faster with fewer steps.
I don't see it. I compared a screenshot of one of these to a older T-84, and it looks like they have same number of buttons, and the buttons are just as cluttered (except the EVO has secondary labels on the keycaps instead of the case).
That's a good thing, since one of the best things about calculators is they typically have a ton of buttons for quick access to a lot of functions.

2 dinners out for a family of four would cover the cost of this calculator. If my kid's school required this for math, I wouldn't bat an eye at purchasing one.
I needed a Ti-83 for school in 1996-1998. If you couldn't afford one, the school would loan you one for the semester. Band instruments were the same way.
Well, it is ;) The Swiss Micros clones are pretty awesome:

These are clones of various older calculators.
With phone emulation, I probably need half a calculator. I have three.
That said, I find it really hard to believe that they can't provide better specs and feature set for the cost. User-available memory of 3.5MB is incredibly low, especially with Python support. These could be really cool handheld computers if TI put more effort into their devices that already have a massive install base.
Currently, most of their popularity in my experience is "lock in" effect from teachers who are familiar with TI calculators and lab / curriculum materials that are specifically built around teaching through TI calculators. At this rate they're charging a lot and resting on their near monopoly status in education, which I'm sure is very profitable for TI.
There used to be a great app called WabbitEmu that emulated these devices on Android. I think they got a cease and desist but it was pretty neat to have back in the day
