Hello, I´m from Mexico, studying Mechatronics Engineering. I´ve got a TI CX a year ago. My university didn´t allowed TI during calculus exams, and I was cool with it. However, now I find myself using integrals and derivatives on a more regular basis throughout most of my classes, and I thought it might be useful to install CAS on my TI CX. So, I was wondering if mine would qualify to do the installation.
TI CX
serial: 2169008177 P-0612E
OS Version: 3.9.0.463
Thanks for the help 

Update:
Ok, I just read that A-I models can work, that´s great.
Now I don´t know if I need/can perform a downgrade...
