Sure you have a chance. I’d suggest you pick out a few elite schools that fit your academic interests, preferred environment etc. and craft thoughtful applications.
But understand that the top schools, with single digit acceptance rates, must be considered reaches for any unhooked applicant. There are simply more well qualified candidates than spots available.
Do the research and create a well balanced application list with reach, match, and safety schools that appear affordable and that you would be excited to attend.
