Can I make it to an ivy league school ?

I really want to go to UCLA or and Ivy League school like Princeton (dad wen't there) or Columbia (mom wen't there). Im not sure if i can do it though. I'm a junior and i've already taken five AP cles and 2 advanced cles. I plan to take three more AP cles next year and I volunteer at my local hospital and have been number one on my varsity tennis team since i was a freshman. I've also been to Africa with my parents twice to help in a childrens hospital (not sure if that helps)... My current GPA is a 4.5 and my ulative total is a 4.15 and im third in my cl. I'm president of the National Honor Society, Vice President of Black Students United, and a member of the California Scholarship Federation...So do you think I can do it?
