TI89 is allowed on both ACT and SAT. It does not have a QWERTY key format, nor wireless communication device, as for the algebra systems thing, u can put that on the 83 if u wanted. anyways, the proctors check calcs in both tests and clearly read the TI-89 on my calculator and approved accordingly.No, Ti 89 calculators are not allowed on the ACT niether are Ti 92s. Any calculator with a QWERTY key format or wireless communication device, as well as, calculators with built-in computer algebra systems are prohibited.
If you completely cover the infrared port on wireless communication devices they are allowed.
