Unless one is a hooked applicant (recruited athlete, legacy although this may go, donor child, or underrepresented minority although who knows what will happen with that after recent court decision), one really must have something special that the college is looking for. Your grades and scores and AP rigor are good enough, but there are thousands of applicants with similarly good grades and scores. Is there anything else you are really good at, that sets you above the other applicants? That is what you need to get into the highly selective schools.
