As Dixielo said, you are fine. I know folks who got in with a few C's. Again, it all depends on who you are competing with and how well they have done.
And you are right about the deadlines being screwy. I was really waiting on SW to call me first but another school replied faster so I went with it-and their deadline for acceptance was way before SW even called me. I CAN'T SAY WHICH SCHOOL BECAUSE IT IRRITATES CERTAIN PEOPLE THAT I AM EVEN ON HERE! But I was waiting on SW up until a few weeks ago. My major factor was cost and didn't want to dive in the MSN program not knowing what I was getting into! SW is cheaper but since you can't work full-time realistically, you will need assistance with day-to- day expenses like gas,food, and a tent. So that is why I went to THE OTHER SCHOOL!
And each school does have different criteria. IMO, SW has a good setup so a person knows what to achieve to get in. With UT, UM, etc. it is a cum G.P.A. and a grade of C or higher in sciences with the disclaimer that those are the minimum requirements but to be competitive you need ....
And people for some reason need to let everyone know their NLN score and grades- I guess it is good for people to get some idea of what is needed to get in, but I think you have an excellent chance! What are your thoughts on getting a BSN?
