As someone who also menu-3-1'd their way through the SAT, I'm surprised it was ever allowed. Super useful outside of school but knowing that a good portion of my classmates using Ti-84s were doing the same problems on paper felt rather unfair.
replyCollegeBoard only seemed to realize recently, the ban on CAS calculators on the SAT, PSAT, and AP exams came last September if I remember correctly, maybe August or October
replyI vaguely remember they were banned by a proxy that stopped working after the Ti-89 came out: no QWERTY keyboards
replyOriginally that blocked the Ti-92, but then the Ti-89 and Nspire line had numeric keypads + CAS
Ah yes, I had a 89 Titanium (bought with the funds from a math prize) that felt like sanctioned cheating for College Board exams. The year I took the AP physics test, there was a surreally difficult integral or differential equation that I owed completely to the calculator. I never did as well in math competitions since getting that thing, but no regrets.
