bmcc Nursing program 2015

Hello future Nurses:)

1- Im very confused with the whole calculating of the 4 prerequisites. can some one explain to me in a very detailed manner how it actually works? I'm transferring over but every time I call the nursing department they seemed bothered to answered any questions. They were just rude and not helpful. The lady I spoke to told me that the GPA is based on Everything I have taken and that its an overall GPA that they look at (every class). Now after reading all these forums I understood that the GPA is calculated by only the 4 prerequisite classes. so really what is it??? my understanding from reviews students have shared is that if I get As on all 4 prerequisites that my GPA is a 4.0. is this correct? Now what the lady in the nursing department gave me to understand is that it is not this way. My GPA is going to be calculated from every class i've taken. Is she right or are the students right? PLEASE HELP !

2- im currently going in with a 2.0 GPA but im retaking my 4 prerequisites to ace them with As. If I pull this off and I ace the HESI A2 exam with a high grade do I have a shot at entering the night/weekend Nursing program even though my grades from my other schools weren't good???

3- If the students are correct and the GPA is based on the 4 prerequisites is it the same for the night program? for instance they calculate your GPA on the 4 prerequisites like the morning program or does the extra classes the night program requires get factored in ? for instance the 4 prerequisites plus CHEM,BIO, and the other classes? example(As on 4 prerequisites and A in chemistry, A in BIO2, A in the other classes = 4.0) or is it (As in all 4 prerequisites =4.0) is the GPA calculated the same as the Day time nusing program?
