<p>for supplementary recs on the common application, do we have to mark it supplementary so the colleges know?</p>
<p>i think it would make sense. For the colleges that provide supp rec forms, they are always clearly marked supplementary.</p>
<p>for common app, since it does not have specific supplementary rec forms, i think a recommendation on an institution letterhead should be fine. colleges will be able to tell that it's a recommendation.</p>
