I'm currently in my 2nd year in UF's Acute Care DNP program. It's a great program. Honestly, GRE scores are not incredibly important for the program. As long as you accomplish at least a 500 on both sections, that's all the care about. I made a 530 on the English and a 570 on the Math. I know of people who have made lower. I also know of people in other UF nursing programs
who scored below the 500 and were accepted to those programs.
I would say the most important parts of admission would be the your admission letter (statement of goals). Make it interesting. Everyone puts the same thing, there looking for something special. I'm not sure if you're considering going all the way for the DNP (you can still opt out at the MSN level til like 2017) but you should say your are. They love their DNP program. They also love their PhD programs. I'm not saying you should lie, but you should make one of your goals a DNP. They also love people who want to teach and give back. So, consider those things in your letter. Mostly really bring out yourself, because I'm sure there is something interesting about you.
Furthermore, I would actually go all the way for the DNP. Most people don't. In fact, I can't think of one other than myself who is going for it. You have to spend another year in the program but, they do give you scholarships... something none of my MSN classmates are getting. My scholarships pay for about 1/4 to 1/2 of tuition each semester, depending on the semester.
Honestly, I think you'll have no problem getting in. The Acute Care program is still relatively small in comparison to the Family program, which can be very difficult to get into. The AC program grows a lot each year, but their very eager to keep expanding it.
Good luck. Let me know if you have any other questions.
