Hi hdak! Good luck with your continuing studies and I hope you have a good shot at getting in! I believe a large part of why I got in was my grade trend and how I talked about my experience working with patients. On my transcript is shows all As and then a few Bs before the summer of 2016. Then I got a C in anatomy that summer! I was absolutely devastated and thought my chances of getting into any BSN program were gone! So, I buckled down and worked my butt off. Every single class after that summer I got an A in, including Physio and Microbio. I know in the online info session they mention that they really look at your grade trend, so I like to think my improvement was a large reason for my acceptance.
Additionally, I'm only an intern/volunteer at a hospital and had about 400+ hours over the course a year and a half when I applied. I believe what made me stand out was using my experiences with patients in my essays and conveying why those experiences confirmed I wanted to be a nurse/what I got out of those specific experiences. So, make sure you're really getting everything you can out of your job, and maybe even write down those unique experiences so you can write about them later! When I had my interview, there was an opportunity for me to really go into depth about what I did as an intern at the hospital and they really seemed impressed with how much I was able to do. My impression is that explaining that bit on my resume really enforced my experience because they didn't seem to realize I could do as much as I did when just glancing at my resume. So, make sure to emphasize points that you think make you really stand out if you get to the interview portion!
Sorry for the long response, but I really hope this helped! Good luck with your studies!
