What are my chances for UF, FSU, and UCF?

[imstressedlol]

So I am currently a junior in the IB program, and looking at my stats I really am not doing too hot. For starters, my unweighted gpa is sitting at about a 3.3 and my weighted a 3.7. My first and only SAT score so far is just at a 1130 (which I know is extremely low, I am a very bad test taker), but I plan on retaking it multiple times and hopefully getting to at least a 1300. As for my extracurriculars, I have done theatre and been a thespian for all of high school, I have done the school dance team, and I am in Rho Kappa honors society. I also do have a YouTube channel which I will be trying to concentrate more on in the summer. I am fully aware that I don’t have anything too good to offer and that being in IB is not going to automatically get me into any school I apply to. In fact, I also wanted to ask if getting one D for a semester grade in IB SL Biology will completely kill my chances of getting into any decent college (because that has been especially worrying me.) Anyways, I plan on applying to UF, FSU, and UCF and would like to know my chances for getting accepted into these schools and what I could do to increase them. I am willing to hear any feedback anyone has to give me, thank you!
