What is the difference between an AA and AS degree?

The AA degree is Associates of Arts

The AA degree is a two year program that fulfills the requirements leading up to the BA degree (an additional 2 years beyond the AA degree)

All the credits earned for the AA degree can transfer to a 4 year university.

The AS degree is Associates of Science

The AS degree is either a one or two year program depending on your course of study.

Some of the credits earned for the AS degree may be able to be transfered to a 4 year university.

The best route, for the serious student is to go for the AA. Attending a community college for the first 2 years is half as expensive as doing those first 2 years at a university.
