Thanksgiving

I am currentally finishing up my junior year of college, and I have to start applying to colleges this fall. I really want to go to nursing school, and possibly join the army or navy nurse corps when I graduate. But unfortunatly, I didn't apply myself very well in high school, expecially my freshman year, and have only a 2.8 gpa. I have been researching a lot of schools, and everyone says they reccomend at least a 3.0 gpa. My SATs are good enough, they reccomend 1000 math and reading, I got 1100. I have done a few extra-curriculars, including community service clubs, and school newspaper, and I have voulnteered in the hospital here all my junior year. Also, my school has a tougher grading system (92,83,74,65 scale). Will that be taken into consideration? Do you think I still have a shot at a four year nursing program? If I don't get in my freshman year, I was thinking that I could try my sophomore year, after I got a lot of my core classes out of the way, and hopefully did really well in them. Would that work? Thank you!
