Will I get into Georgia Tech?

I'm a junior this year and I'm currently taking AP Chemistry, AP Calc AB, AP U.S. History, and AP Lang./Comp.; however, I am not performing successfully in APUSH and now possibly including math. Last year, I took AP World History (ped the AP exam w/ a 4) and all honors cles. I'm failing APUSH right now. I have an 89 in math right now but I REALLY BOMBED a test recently and I'm pretty sure I'm failing now. I'm scared my chances are limited now in getting into GT. Yet, I am involved in Math team, Science Olympiad, French Club, Science National Honor Society, Beta Club, and Medical Bowl. Nationally, I got nominated for Leadership of America and People to People Ambador Program. I am a member of National Society for High School Students. Despite all these, I am declining in my SAT scores each year and now my failing grade will drop my GPA by MANY POINTS. So, judging by this, will I have a chance to get into GT? My dad went there and I really want to go there. Thanks.
