I'm done with the pre-req courses and get GPA 2.66 for anatomy, physiology and micro, I have 3.5 for my overall GPA. I study in CA, in my case, do I need to retake one of the sciences to improve my GPA? As far as I know, the community college will evaluate students by the pre-req and overall GPA, but I have no idea that which one is more important. My frineds told me that even if you retake one course and get A, the school will still calculate ur old GPA, they never use ur new GPA. I have no idea whether I should retake or not. I've already meet an ice, please help me, I don't wanner give up the hope of becoming R.N. Please help me!
