Withdrawn admissions offers?

<p>Is there a specific GPA where colleges draw the line? From the looks of it, my GPA at the end of the 1st semester this year will have dropped about .6 from the cumulative GPA's from freshman, sophomore, and junior year. I might receive a C and three B's, and they're all regular classes. I'm applying to nursing school too, so do you think they're stricter? If I get acceptance letters from colleges this December, will they probably withdraw my admission offer once they see the mid year report / transcript at the end of 1st semester??</p>
