Can I get into Stanford,MIT, ect...?

I would like to major in engineering, and I am wondering if i actually have a chance of getting into some of these schools. My freshman year GPA was 4.375, sopre year GPA 4.375, Junior year 4.5, and senior year (potentially) 4.8. I took the maximum of 8 cles each semester. I have only received 2 b's (1 in an honors course and 1 in an AP). I have taken 5 math and 5 science course and received high marks in them. I've taken relative electives (CAD - computer aided drafting - for instance) I have not been involved in sports or leadership through school , however I have been highly involved in community service (Key Club, issteens, food drives, tutoring at a center weekly) as well as church activities (missions work and such). I have high test scores. I am extremely nervous about getting into college. I would love to get into MIT, but I don't think that will happen. Princeton, Carnegie Mellon, Stanford and NYU are my top schools (I have backups!!). Do I have a chance?
