I did not ask them about that. My case is, I ruined my first two years of college so my cumulative GPA on NursingCas is 2.86. And after all the retakes, it shows 3.56 on my undergrad transcript. Thats what makes me think GPA is not a big factor, but personal statement is. And you are right that not all prereqs have to be done at the time you apply. I am personally taking Micro this upcoming Spring to fulfill.
