Finding Colleges

Hi, I’m a sophomore in high school and I’ve been looking at colleges for a few months now, just to for figure out were I should aim. I’m interested in mechanical and aerospace engineering, but I’m open to other majors do I would like the schools on my list to be good all around. Is prefer it to be east of the Mississippi, smaller than 10,000 undergrad students, and a contiguous campus. The top schools on my list right now are Northwestern, Duke, Princeton, and Carnegie Mellon. I don’t really have any stats but I’m doing sat and act prep, I’m in all of my schools ap sand honors classes offered for 10th grade, and I have all A’s sand hopefully this will continue as I take even more aps and honors courses over the next 2 years. I feel like I don’t have enough options where else should I look?
