Keep in mind that Stony Brook doesn't only look at your gpa, but they look at your overall application. The essay part of it is what sells you and it presents to the admissions committee who you are and why you want to go to SBU...not all incoming students have stellar gpas. If nursing is what you want to do, then go for it. We all have "bumps" in the road, but that shouldn't stop you from pursuing your dreams. Best of luck!
