diphthong

From what I understand, most schools require a minimum of a 2.5 science GPA but I only have a 2.3. My overall college GPA is around 3.4 but it seems like it doesn't matter as much as the science GPA. I already finished all the prerequisite courses so there aren't anymore classes for me to take. People always tell me I can raise the science GPA by retaking those classes, however I already retook one of them once and that was the maximum times I can retake it. I've made a lot of mistakes around 2009 (which happens to be around the time I took those classes) so that's the reason for my low GPA but I've became a much better student since then. Right now I'm trying to find every remaining option I have left, so I was just wondering if there's anything else I can do or where I can go to even apply to a nursing program. I really don't want to give up on nursing and I want to make this work. Thanks.
