Find out the classes needed to transfer to a four-year university or college for the major you are interested in pursuing. Your community college can print out the classes you should take if pursuing a four-year degree after getting your AA. Talk to the counselors.
More than likely, you will need many general education classes (certain amount of English, math, history classes, electives, etc.) In addition, you can fulfill your pre-req classes before you transfer so that you don't have to take them later.
