retake a C and transfer unit limit?

<p>Hello~ i just have 2 questions i was wondering if someone can answer</p>

<p>1)is there a unit limit when applying to the Uc's from a private college (not a cc)
cause i know for a Uc to Uc transfer student you can't exceed a certain # of units like 80 or 90 units. i just don't like my private school so need to get out! i use to be a cc student just last year, i just made the wrong decision for my school</p>

<p>2) so i received a C in one of my cc classes so i was wondering if you can retake that course at a different cc.. i know you can't but i just want to show them i can do better..i don't want it to be considered into my GPA or anything but is that possible </p>

<p>Thank you</p>
