Advice on how to get into BSN program

I was originally a mechanical engineering student, accepted into the program. I joined the national guard to gain some experience and to help pay for school. I became a 68 W Health Care Specialist/ Medic and am a medic with an infantry line unit. With this I got my NREMT-B out of the way, and upon returning home, got my Colorado EMT-B, started school right away switching majors to Nursing, to apply to get into the BSN program. I have one more semester before I can apply (I need A&P 2, Organic Chem, and Developmental Psych), and to take the HESI A2. Before I left my GPA suffered somewhat from an AP Calc 1 class from high school, where I did not know I would start out with a 2.0 GPA if I transferred that credit. My first semester, I took Calc 2, and and engineering class, as well as an elective. I got a D in Calc 2, but a B+ in one and an A in the other. The Calc classes are not applicable to my degree, but my Cumulative GPA is still suffering as a result. I need a 3.0 minimum to even be accepted. I have also been trying to get a job as an ER tech on the civilian side, but have had no luck so far, but I am volunteer firefighting and doing medical calls as an EMT with the department to further my background. I am also going to start volunteering with one of the hospitals to increase my volunteer hours. I have been knocking out Pre-Reqs for the program the last 2 semesters, bringing my GPA up to almost a 3.0. It currently sits at a 2.98. I am getting B's and A's in all my classes so I bring it up. What I'm really trying to get at here is, aside from my not the best GPA, will my volunteering, having my medical background, and continually striving to bringing my GPA up, as well as a good HESI score, likely help me get accepted to the program?
