Calculators

I don’t know which calculator to get for senior year and possibly college. I’ve used the following calculators but I don’t know which will be best for my purposes.

Calculators: TI Nspire CE
TI 89 Titanium
TI 84+ CE

Next year, I am taking AP Physics C, and multi variate calc. I plan on majoring in engineering or something in STEM. I need a calculator now because I’m taking the SAT in August. I loved the 89 last year for the SAT because it factored for me and it was pretty nice, but I saw many college professors don’t like the 89 because of its capabilities. I don’t know if this matters but my top school is Carnegie Mellon followed by Cornell and Northeastern. Thanks!!
Sorry! I don’t know where to put this.

I’d get an 89 AND some cheap 4-function from Walmart or whatever. My calc teacher told me that college math classes will not allow an 89… or an 84… or anything better than a 4-function. The 89 is just so nice, especially if you’re taking Physics C, that I wouldn’t worry about it for college. The thing will last for years, and in the worst-case scenario, you could just resell it after you graduate HS.

Ok!
