<p>I’m not seeing much in common among the safeties. It looks like you would prefer a more conservative campus (Pepperdine, Belmont). In that case, among the safeties just keep Belmont and whatever is your in-state (Kentucky? Pennsylvania? Illinois?). </p>
<p>Lots of people apply to 15 or more schools but there tends to be a theme or thread connecting them. In your case, applying to 15 schools may take more effort if they require supplemental essays, simply because these essays may not overlap much. You’ll be writing 15 (or more) individual essays, instead of tweaking two or three essays to fit the school.</p>
