If you can get the college degree with your mom's financial support and maintain your sanity and well-being while doing it--great!
If you start to hate life due to the guilt and BS that your mom or other JWs might make you endure during college, don't allow it to get so bad that your grades go to shite, and don't otherwise allow the JW crap you might experience to manifest itself negatively in your actions or cause you to lose your will to live and thrive.
Good luck! :-)
