Why are you getting two AA degrees? My concern is that you might have too many credits and the institutions may not accept you. You need to be on campus, at least two years-equivalent of courses, taken at the site where you hope to get your BA degree. What has your transfer counselor at your community college advised?
“Students will be granted up to 70 semester/105 quarter units of credit for lower-division coursework completed at any institution or any combination of institutions. For units beyond the maximum, subject credit for appropriate coursework taken in excess of this unit limitation will be granted and may be used to satisfy requirements.”
The UC‘s may give you some leeway, however, given that they are so tight for spaces for incoming students you’re risking your admission chances.
How are you funding your education? If you’re using financial aid from the State, they may limit how many years you can access financial aid credit-like the CalGrants. If you use it up, you won’t have any money left over to pay your final years at the university level.
Speak to your transferred admissions counselor at both your community college as well as at your target UCs. All the UC’s are different in how much leeway they’ll give you.
Getting two AAs won’t significantly improve your chances.
Also, something else to consider is where these universities are located and what their housing issues are. Because California is such an expensive real estate market, the competition for housing can be brutal in certain university areas. Your financial aid dollars will only stretch so far.
Another thing to consider is what you hope to do with your degrees? Are you planning on continuing at the graduate level? Then what? Those of us with degrees in the humanities, have it a little bit rougher. Have you researched your occupational marketability?
