We are transitioning to the new TI-Nspire CX CAS calculator. IT MUST BE A CX CAS

 TI-Nspire CX CAS.
ALL INCOMING FRESHMEN (Class of 2021) and Sophomores (Class of 2020) and Juniors (Class of 2019) are REQUIRED to purchase this calculator for use in their math and science courses throughout their four years at Cathedral.  This calculator will be especially helpful for AP courses such as Physics, Calculus, and Chemistry, and can be used on the SAT as well.  RETURNING SENIORS are NOT required to purchase this calculator, although they are welcome to if they wish.  All seniors may continue to use the TI-84 in their math and science courses.
Here are some links to purchase the TI-Nspire CX CAS
