I just need an outsiders opinion on my chances of getting into these schools

I chose the schools I did basing them around the QuestBridge partner schools. In the very likely chance that I am not a finalist or a match for any of these schools, my plan is to go to UGA and then transfer into GA Tech. Additionally, I am extremely up to the challenge of taking on the extreme rigor of these courses. My school does not measure up to the schools that fellow applicants attend. We have had one person in the 9 years my school has been open accepted into an Ivy League. Our school does a relatively atrocious job of preparing us for college, and their goal seems to be to send everyone to public Georgia University and neglect considering anything else. I am retaking ACT in September, and I am also taking Biology E and Math II subject tests on October 1.
