If it was 7-10 years ago since you took classes, and you do not have a degree (Associates, Bachelors), then most likely it does not count for transfers, so "retakes" don't apply, so to speak, because the course has "expired" so by default, you would take it over because the course in itself has evolved...so it would be a clean slate.
In my area, that was how it was explained to me. I had an AA, the classes I took at another university were not counted because they were 10 years old when I went back for my nursing degree, so I had to take over my "arts" in order to complete my degree, and they did not transfer over.
As far as my science classes, I needed to get an A and a B in at least 3 of my classes, so I was recommended a CLEP-like process through Excelsior college. I self studied and took a test to get a passing grade. I did A&P parts I & II (one test) and Microbiology (I). I got an A and B respectively.
Find out from the schools directly, be upfront about your situation. If you were a dependent (under 24) when you first went to school, and are above 24, you are an independent student, and the qualifications may change. Ask each program to clarify. If it matches up, you have a chance for a "clean slate." Most places have no issue for giving in the information, and pointing you in the right direction, financial aid waivers, etc. when you explain you situation, provide clarity, and have a plan to follow out your goals. Good luck!!!
