I am not sure you can retake at a CC. Here's why.
I'm currently at ARC, planning to go to UC Davis when I finish my prereqs. You can take a class up to three time IF YOU FAIL/WITHDRAW. That is, unless you failed the course, withdrew from it, or for some other reason were unable to complete it, then you can take it again, up to three tries. If you complete the course with a grade of a C or above, you're done. Can't take it anymore. This is how I remember it. Of course, try to get a counsellor to get some sort of exception or whatnot. Also, I'm not sure taking it at Davis affects your ability to take the same course at a CC level. I think the rule only applies within the CC system because the government foots massive amounts of the bill through the bog waiver, whereas you pay to go to UC Davis.
