Transfer classes from university to community college?

I took a year's worth of classes at a 4-year university before high school. My high school transcripts aren't that great, I would not be able to apply straight off to a 4-year university without transferring in from a community college.

I'm now in my second semester in community college.

Can I transfer my university coursework to the community college toward completion of my AA? ...toward transferring to a 4-year university?

Should I complete the rest of the transfer coursework and apply to a third school later on, combining coursework from both schools to meet transfer requirements? (But then skipping the AA.)

I would rather not re-take classes... but since I was 13 when I took them, I have some Cs at the university that would bring my cumulative GPA down. What's your advice?
