If you have a ba degree how long much longer would it take to get an AA degree?

If you are applying to a community college to take an AA, most have a transfer credit limit. They may transfer anywhere from 32 to 40 credits if they are usable toward the AA which could be 60 to 64 credits to complete. Still, I'm wondering why you would want to obtain an AA after already completing a BA. The AA degrees are typically designed to transfer to a four year college or university to pursue the BA or BS. Their are many with a BA and BS that take an associate in applied science being that it is very career oriented. In other words, nursing, physical therapy, etc., but rarely do I ever see someone taking the AA after having a BA or BS. Well, you most have your reasons.
