I think you will get in! But UF is turning into a crapshoot, more competitive each year, so you never know but I do think you are at level.
Yes, I believe they do give preference to veterans and their families, but I’m not 100% about that.
And also, they prefer AP/IB over dual enrollment because it’s more standardized, but they won’t discredit you or put you at a disadvantage if you did DE.
I hope this helped and if you get in, say hi to me on campus next year! Lol I’m class of 2020 
also, if you have any specific questions about regular admission, honors admission, or anything an incoming freshman would know, feel free to message me!
