You might want to apply to a few more schools, to add redundancy to the process; i.e. more than one reach school. But for the schools you’ve stated thus far, your chances seem reasonable. Colleges receive a report from your guidance counselor about the nature of your high school, so they’ll be pretty understanding about your difficulty regarding involvement in extracurriculars. For Cornell, you’ll need a higher ACT score, but for the others, your scores are good. Good luck!
