<p>I would caution against overt optimism in the admissions process, as it can lead to disappointment (my sister thought she would make it in at Brown after positive feedback from CC, but was waitlisted, and then rejected. She was very upset but ended up loving the LAC she went to!)</p>
<p>That being said you are the applicant type each of the schools dreams of, so I think you will likely make it in at more than one.</p>
<p>Perhaps add Cornell, Columbia, and Hopkins/WUSTL/Northwestern to your list? That way you have some wonderful options in case HYPS falls through.</p>
