Withdrawal....?

ok so i am in southern california and right now it is almost IMPOSSIBLE to get into an ADN program unless you have like a 4.0 right?

well some schools also look at retaking classes/withdrawals and they will negatively affect you.

well see i have a withdrawal but it was more of a mistake then a withdrawal

heres the story:

i had taken the first class of a bio major biology series at JC then i transferred to 4-yr university and have to finish the biology series (2 more classes because i was a bio major at a quarter system college) well they told me that i had to take the first of the biology series, well i thought i already started the first of the series at the JC, but maybe it transferred differently. So i started class at the university when i look at my transfer progress report and it says i repeated the first class of the biology series.

i was like wow i have been in class (i have already taken, no wonder it was boring and very familiar lol) for 2 weeks past the add/drop period so i knew i would have to take a W.

so now i am worried because i don't want it to reflect negatively to the NS's i want to apply for

anyone have advice or experience in this (or in applying to a so cal ADN schools

much appreciated!!
